I-Direct Roving Tex: Ukukhetha i-2400, 4800 okanye i-9600 ye-Pultrusion kunye ne-Filament Winding

Umgca we-pultrusion ongahlali ucocekile udla ngokuba nengxaki ye-tex, kungekhona ingxaki ye-resin. Iprofayili iphuma ineziqwenga ezomileyo ezikoneni kwangoko nje ukuba unyuse isantya. Okanye umxholo weglasi ungaphantsi kwento efunwa ngumzobo, kwaye akukho bushushu bokufa buvala umsantsa. Okanye yonke indawo kwi-creel ihlalwa kwaye icandelo lisaswele i-fiber. Akukho nanye kwezi ebonakala njengempazamo yephepha ledatha, kuba akukho nto kwiphepha ledatha engalunganga. Zibonakala kuba i-tex ikhethwe kwikhathalogu endaweni yomgca.

Esi sikhokelo sisebenza ngokukhetha phakathi kwe-2400, 4800 kunye ne-9600 tex ngendlela injineli yenkqubo ehlangabezana ngayo nayo: ukuba inani lilinganisa ntoni, kutheni ii-roving ezimbini ezine-tex efanayo zingatshintshi, zingaphi iziphelo ezifunekayo kwiprofayili ethile, kunye nokuba inyathelo ngalinye liya kubiza malini.

Yintoni i-tex eyilinganisayo ngokwenene (kunye nenani le-yield elingasemva kwayo)

I-Tex yi-linear density: iigrams kwi-1,000 yeemitha. I-2400 tex roving inobunzima obuyi-2.4 g kwimitha nganye oyitsalayo; i-4800 tex inobunzima obuyi-4.8 g; i-9600 tex inobunzima obuyi-9.6 g. Yiyo loo nkcazelo ipheleleyo, kwaye kufanelekile ukuyichaza ngokucacileyo kuba i-tex isetyenziswa njengesifinyezo segama elithi "ukutyeba" ngendlela efihla izinto ezimbini engazichaziyo: ububanzi be-filament ngaphakathi kwintambo, kunye namandla e-laminate oza kuyakha kuyo.

Ukuba imizobo yakho okanye isebe lakho lokuthenga lisebenza kwiiyunithi zase-US, inkcazelo efanayo ibonakala njenge-yield kwiiyadi ngepawundi, echaza ipropati efanayo kwelinye icala:

Kumgca omnye:yd/lb = 496,055 ÷ tex.

iteksi	g/m	≈ yd/lb
1200	1.2	413
2400	2.4	207
4800	4.8	103
9600	9.6	52

Ukuguqulwa yi-arithmetic, kungekhona uqikelelo lokuziphatha kwezinto: 1 lb = 453.592 g kunye ne-1 yd = 0.9144 m, kwaye i-constant iyaphuma kwezo zibakala zimbini. Kubalulekile kuba umsasazi wase-US ucaphula "206 yield" kunye nedatha ye-mill ethi "2400 tex" zichaza ukuzulazula okufanayo kwiinotations ezimbini. Guqula ngaphambi kokuba uthelekise, kwaye ungaze ubeke umfanekiso we-tex kunye nomfanekiso we-yield kwitheyibhile enye ngaphandle kokubhala ilebheli yeyiphi ikholamu.

Iteksi efanayo, umsonto owahlukileyo

Ababoneleli ababini banokucaphula i-4800 tex baze bathumele imicu eziphatha ngendlela eyahlukileyo, kuba i-tex sisiphumo sezigqibo ezibini ezizimeleyo: ukuba zingaphi iifilaments ezithwalwa yi-bushing, kunye nokuba ifilament nganye ityebile kangakanani.

I-filament enye ye-E-glass kwi-17 µm ithwala malunga ne-0.58 tex; kwi-24 µm, malunga ne-1.15 tex, kubuninzi beglasi obuqikelelweyo be-2.55 g/cm³. Sebenzisa loo manani kwaye kuvela into eluncedo: i-bushing yemingxuma eyi-4,000 edwetshwe kwi-17 µm emhlabeni kufutshane ne-2,315 tex, ngelixa i-bushing yemingxuma eyi-2,000 kwi-24 µm umhlaba kufutshane ne-2,307 tex. I-tex efanayo, isiqingatha senani lemingxuma, ii-filaments zinkulu malunga ne-40% ububanzi.

Ezi ntambo zimbini azilingani kangako ngezantsi. Inqwaba yeentambo ezininzi ezintle inika indawo engaphezulu kakhulu kwi-resin kwaye isasazeka ibe yibhanti ethe tyaba, enceda ekumanziseni nasekuzaliseni umngxuma obanzi nobhityileyo. Inqwaba yeentambo ezimbalwa, eziqinileyo ziyaphuma kwaye zifunxe ngokwahlukileyo, zimelana nokuvuleka emnyango wedayi, kwaye ziguqulela amandla azo kwi-laminate ngokwahlukileyo. Akukho nanye kwezi zingcono kwi-abstract; zizixhobo ezahlukeneyo.

Isenzo esithethwa yile nto sincinci kwaye singabizi kakhulu: cela ububanzi be-filament kunye nenani leembobo ze-bushing ecaleni kwe-tex. Abathengisi bapapasha i-tex kunye nobubanzi njengeekholamu ezahlukeneyo ngenxa yesi sizathu, kwaye yeyona ndlela ikhawulezayo yokufumana ukuba i-4800 engabizi kakhulu yi-reinforcement efanayo okanye linani elifanayo.

Ibhalansi yobunzima: ukusuka kwiprofayili ukuya eziphelweni

Olu lubalo oluguqula umzobo ube yi-creel layout. Amanyathelo amathathu, kwaye uqikelelo lubalulekile njengezibalo.

Inyathelo 1 - ubunzima beglasi ngemitha nganye.Thabatha indawo enqamlezileyo kwi-cm², uphindaphinde nge-100 ukuze ufumane ivolumu yemitha enye yeprofayili, uphindaphinde ngeqhekeza levolumu yefayibha ekujoliswe kuyo, uze uphindaphinde nge-glass density. Kwi-density, i-2.55 g/cm³ lixabiso elisetyenzisiweyo apha.

Inyathelo lesi-2 — liyaphela.Yahlula ubunzima beglasi ngemitha nganye ngobunzima obuvela kwisiphelo esinye ngemitha nganye, oko kukuthi i-tex ÷ 1,000.

Inyathelo lesi-3 — jikeleza uze uphinde ujonge.Iziphelo zii-integer. Sondeza phezulu, uze ubale umxholo wefayibha oza kuyakha, kuba yiprofayili oza kuyithumela.

Iingcinga, ezichazwe kanye ukuze ukwazi ukutshintsha ezakho: zonke izinto eziqinisayo ziyajikeleza (akukho mat, veil okanye filler kwicandelo), i-target Vf yi-volume fraction endaweni ye-weight fraction, kwaye i-die clearance kunye ne-resin bleed-back azinakwa. Tshintsha nayiphi na kwezo kwaye amanani ayashukuma.

Umzekelo osebenzayo: iprofayili ethe tyaba eyi-100 mm × 6 mm kwi-Vf ekujoliswe kuyo eyi-0.60.

Ummandla = 6.00 cm², ngoko ke imitha enye yeprofayili iqulethe i-600 cm³ yezinto

Umthamo weglasi = 600 × 0.60 = 360 cm³

Ubunzima beglasi = 360 × 2.55 =918 g/m

iteksi	g/m isiphelo ngasinye	iziphelo ezifunekayo (ngokuthe ngqo)	iphela kwi-odolo	g/m ihanjisiwe	I-Vf yakhiwe ngokwenene
2400	2.4	382.5	383	919.2	0.601
4800	4.8	191.3	192	921.6	0.602
9600	9.6	95.6	96	921.6	0.602

Zonke iindlela ezintathu ze-tex zifikelele kwithagethi ngaphakathi kwe-rounding. Yiyo le ingongoma: kweli nqanaba lokubala i-tex ibonakala ngathi lukhetho olukhululekileyo. Umahluko ogqiba ukuba ayikho kule theyibhile.

Oko ukuzuzayo noko ukuhlawulayo xa unyuka inyathelo

Iziphelo ezingamakhulu amathathu anamashumi asibhozo anesithathu ziba yi-192, zize zibe yi-96. Loo mlinganiselo umnye uqhuba iiakhawunti ezine ezahlukeneyo, kwaye azihambi zonke kwicala elinye.

Iindawo zokubumba kunye nexesha lokufaka imisonto.Ixabiso leCreel likwindawo nganye, kwaye kunjalo nomsebenzi wokuyidibanisa. Ukwahlula iziphelo zibe zisiqingatha zombini. Kumgca apho ubude beCreel bungumqobo wokubopha — olona luninzi lwemigca ye-pultrusion — esi sisizathu sokwenyani sokunyuka inyathelo, kwaye asinanto yakwenza nezinto.

Utshintsho lweephakheji kunye nee-slices.Isiqingatha seziphelo sithetha isiqingatha seepakeji, ngoko ke isiqingatha see-doffs kunye nesiqingatha see-splices ngeshifti nganye. Kwi-run eqhubekayo, ukuphazamiseka okuncinci kubaluleke ngaphezu kwe-wet-out figure engcono kancinci, kuba i-splice nganye yindawo apho into inokungahambi kakuhle.

Ukumanzisa.Kulapho ibango lekhathalogu lifuna khona isichazi-magama. I-tex ephezulu inyusa i-fiber throughput ngesiphelo ngasinye, kwaye iphepha lemveliso litsho ngokuthe ngqo: inani le-tex eliphezulu lithetha umsonto otyebileyo, onokusetyenziselwa ukwandisa umxholo we-fiber kunye nokukhawulezisa imveliso. Oko kuyinyani, kwaye sisivakalisi malunga ne-throughput ngesiphelo ngasinye. Akusiso isithembiso sokuba i-impregnation yakho iya kuhlala injalo.

Ixesha lokuhlala ebhafini libude bebhafu obahlulwe ngesantya somgca. Ibhafu eyi-0.6 m esebenza kwi-0.3 m/min inika umsonto ngamnye imizuzu emibini kwi-resin; kwi-0.6 m/min inika umzuzu omnye; kwi-1.2 m/min, imizuzwana engamashumi amathathu. I-bundle erhabaxa ineengqimba ezingaphezulu ze-filament ukuze i-resin ingene, ngoko ke ixesha elifanayo lokuhlala lithenga ukungena okuncinci. Phakamisa isantya se-tex kunye nomgca kunye - nto leyo kanye impikiswano ye-throughput ekhuthazayo - kwaye ezi ziphumo zimbini zidibene nxamnye nokuphuma kwamanzi.

Isisombululo somxholo wefayibha.Isiphelo esinye se-2400 tex sitshintsha i-Vf malunga neepesenti eziyi-0.16 kule phrofayili. Isiphelo esinye se-4800 tex sitshintsha i-0.31; isiphelo esinye se-9600 tex, yi-0.63. Ukuba iinkcukacha zakho ziyi-60 ± 1%, zonke ezi zintathu ziyasebenza. Ukuba usika ngaphakathi kwefestile enenqaku elinye - ukusuka kwi-62% ukuya kwi-63%, okanye uthelekisa ikhuphoni yomthengi - i-2400 tex ikunika amanyathelo amathandathu ukunqumla kuyo, i-9600 tex incinci kakhulu.

Xa zizonke, le ndlela iyafana: iindonga ezincinci, iindawo ezincinci kunye nokunyamezelana okuqinileyo kwefayibha kukutyhalela kwi-tex ecolekileyo, apho iziphelo ezongezelelweyo zithenga isisombululo kwaye zisasazeke. Iindawo ezixineneyo, imijikelo emide kunye nemigca enomda we-creel ikutyhalela kwi-tex eqobayo, apho iziphelo ezimbalwa zithenga ubulula. Imigca embalwa kakhulu inqunyelwe zizo zone ngaxeshanye, yiyo loo nto impendulo yahlukile phakathi kwezityalo ezimbini ezisebenzisa iprofayili efanayo.

Ukuxinana kwe-pultrusion kunye ne-filament: i-tex efanayo, iisilingi ezimbini

I-tex efanayo iziphatha ngendlela eyahlukileyo kwezi nkqubo zimbini kuba umda othintelayo awufani.

In i-pultrusion, isilingi yindlela yokungena ngedayi. Zonke iziphelo kufuneka zisasazwe zibe yibhanti ezalisa umngxuma ngokulinganayo, ngaphandle kwezithuba kwaye ngaphandle kokugqithana. Okungakumbi, iziphelo ezincinci zisasazeka lula kwaye zizalise indawo ebanzi, enganzulu ngcono; iziphelo ezincinci, ezityebileyo ziqinile, ziyamelana nokuvuleka, kwaye zinokushiya iikona zilambile. Ngoko ke iteksi esebenzayo imiselwa kukuba zingaphi iziphelo zakho ezibambe idayi yakho kunye nokuba isebenza kakuhle kangakanani na i-pre-die spreading yakho - kungekhona oko kunikezelwa yidathasheet.

In ukujika kwentambo, isilingi sihamba nge-bandwidth kunye noxinzelelo. Xa i-throughput ilingana, iziphelo ezingama-48 ze-2400 tex kunye neziphelo ezili-12 ze-9600 tex zinika ubunzima obufanayo ngeyure. Iziphelo ezilishumi elinambini zithetha indlela emfutshane yoxinzelelo kunye nezikhokelo ezimbalwa, okulula ukuzilawula kwaye kulula ukuziphinda uzifake. Kodwa nganye kwezo phakheji zilishumi elinambini ngoku ithwala ukugeleza kobunzima okuphindwe kane, ngoko ke i-snag enye, iphakheji enye embi okanye i-tension spike enye ibonakala njengesiphene sebhendi kwindawo ebanzi. Ukujika kukwakhathalela ububanzi bebhendi nge-pass nganye, etshintsha nge-tex: ukuhambahamba okurhabaxa kugubungela ububanzi obuninzi kwi-traverse enye, okutshintsha inani lama-pass avala umaleko.

Ukuzulazula okufanelekileyo kwiiphelo ezingama-383 ngedayisi ye-pultrusion kunokuba lukhetho olungalunganga kwiiphelo ezili-12 kwi-mandrel. Inani elifanayo, isilingi eyahlukileyo.

Inombolo yokukhupha elinganisa ubungakanani be-creel yakho

Ngaphambi kokuba uzibophelele kwi-tex, jonga ukuba yintoni ekufuneka inikelwe yi-creel yakho:

Izibalo zingumgca omnye:kg/h = iziphelo × (tex ÷ 1000) × isantya somgca (m/min) × 0.06.

Kwi-25 m/min, ukuhambisa i-172.8 kg/h kuthatha iziphelo ezingama-48 ze-2400 tex, iziphelo ezingama-24 ze-4800 tex, okanye iziphelo ezili-12 ze-9600 tex.

iteksi	iphela nge-172.8 kg/h kwi-25 m/min	iphela nge-345.6 kg/h kwi-25 m/min
2400	48	96
4800	24	48
9600	12	24

Eli linani elibeka ubungakanani be-creel, ubunzima bephakheji kunye nexesha lokuphuma. Alikuxeleli ukuba umgca uza kumanzisa na - oko kukuthi ukubalwa kwexesha lokuhlala apha ngasentla - kwaye alikuxeleli ukuba iprofayili iza kuzalisa na. Lisebenzisele ukwenza ubungakanani be-creel, uze usebenzise ezinye ezimbini ukujonga ukuba ubungakanani be-creel obulinganisileyo bunokusebenza ngokwenene na.

Akunjalo ngokuyimfuneko. Cela ububanzi be-filament, inani leembobo ze-bushing kunye nenkqubo yobukhulu. I-tex efanayo enolwakhiwo olwahlukileyo lwentambo iya kumanzisa ngendlela eyahlukileyo kwaye ayizukuguqulela amandla kwi-laminate ngendlela efanayo.

Ingaba i-4800 tex "iphakathi" kwe-2400 kunye ne-9600?

Ngobunzima, ewe: kabini kanye nesiqingatha. Ngokwemigaqo yenkqubo, hayi. Inqumla iziphelo ngaphandle kokunciphisa inani lamanyathelo okulungisa, kwaye iphinda kabini ukuhamba kobunzima ngephakheji nganye endaweni yokuyiphinda kane. Ii-trade-offs azikho ngqo, yiyo loo nto ukhetho oluphakathi ludla ngokuba lolo luhambelana nomgca one-creel esisigxina kunye nokunyamezelana okuqinileyo.

Khetha iteksi onokuyibamba umgca wakho

I-Tex sisigqibo somgca esinxiba iimpahla zephepha ledatha. Qala kwicandelo kunye nomxholo wefayibha ekujoliswe kuyo, uguqulele kwiigrama ngemitha nganye, wahlule nge-tex ukuze ufumane iziphelo, uze ujonge izinto ezintathu ikhathalogu engenakuxelela zona: ukuba i-creel inendawo, ingaba ibhafu inexesha, kwaye ingaba isiphelo esinye silungelelaniswe kakuhle.Khangela iimveliso zokuqinisa i-fiberglass zeRuifiberukubona uluhlu lokuqinisa ecaleni kwalo mgca wokuzulazula, kwaye ufundeukuzulazula ngqo ukuze kuqhutywe i-pultrusion kunye ne-filament windingiphepha ngaphambi kokuba uthumele i-RFQ echaza inkqubo yakho, icandelo, i-Vf ekujoliswe kuyo kunye ne-resin — okukhona uchaza ezo zininzi, kokukhona impendulo ibuya sele ihambelana nomgca wakho.
