Mat Yesimbi Yakachekwa vs Mat Yakarukwa (uye Mat Yekubatanidza): Maitiro Ekuvaka Laminate Yako

CSM inotanga segirazi rinogara richichekwa kuita machira mapfupi — kazhinji 25–50 mm — uye rinoiswa sewebhu isina kurongeka, rozobatanidzwa nepolyester binder ine upfu kana emulsion iyo inonyungudika mu resin panguva yekuumba. Nekuti hapana fiber inomhanya kumucheto kuenda kumucheto, simba rinopararira zvakaenzana kumativi ese, uye pepa racho rinoenderana nemakombere akabatanidzwa ayo jira rakarukwa raizobatanidza kana kusimudza. Rinonyorovesa nyore nyore, rinobatana zvakanaka pakati pezvikamu zvakasimba, uye rinoenderana nepolyester, vinyl ester uye epoxy resin systems pakuisa maoko, kupfapfaidza uye kupinza.

Magadzirirwo akafanana iwayo echinyakare ndiwo anochinjana. Dandemutande rakapfava rinobata resin yakawanda kupfuura yakagadzirwa nejira rakarukwa, saka kushandiswa kweresin pa millimeter imwe neimwe kwakakwira uye simba rayo rakaderera pane fiber inoenderera mberi - nyaya yekufungidzira resin zvechokwadi, kwete chikanganiso. CSM ndiyo inonyanya kukosha pane kunaka kwayo: gel-coat backup layers, corrosion-barrier liners, molding complex shapes, uye interlayer bonding pakati pewound plies.

Zvinhu zvitatu, patafura imwe chete

Bvunza kuti ndechipi chakasimba — jira rakachekwa kana jira rakarukwa — uye unowana mhinduro ine chivimbo kubva kune dzinenge dzese forum dzevatengesi. Mubvunzo wekutanga wakashata zvakare. Laminate haisi murwi wemapepa "akasimba"; iboka remachira, rimwe nerimwe rine basa: kuvaka ukobvu, kutakura mutoro munzira inozivikanwa, kubatanidza makomba akaomarara, kana kuchengetedza pamusoro. Kana wangopa mabasa acho, sarudzo yezvinhu inowanzoita yega: dzimwe nguva ijira rakachekwa, dzimwe nguva jira rakarukwa, kazhinji richichinjana, uye dzimwe nguva jira rakasonerwa rinoita mabasa maviri panguva imwe chete.

Gwaro iri rinoenzanisa mhuri nhatu dzezvinhu zvinogadzirwa nenzira iyo mapoka ekugadzira nekutenga anozvitsanangura nayo - nechimiro, maitiro eresin uye maitiro - uye rinoshandisa data rehuremu rakaburitswa chairo kwete generic ranges. Rinoguma nemuenzaniso wakashanda uye RFQ checklist yaunogona kutumira zvakananga kumutengesi.

Matavi akachekwa: kufukidza, kuenderana uye ukobvu hwayo

Kufamba-famba kwakarukwa: simba rekutungamira

Kuruka kwakarukwa ndiro jira rinorema renyika yeFRP: mabundle efilaments dzinoramba dzichishanda — maroving akafanana anoshandiswa mukukombama kwefilaments, uko common tex values inosvika 2,400 kusvika 9,600 — akabatanidzwa kuita jira rakakombama, rinogona kuputirwa. Nekuti mafibre aya anomhanya nguva dzose pamwe chete newarp neweft, mutoro unofamba usingapindiki nepakati pelayer, ndosaka kuruka kwakarukwa kuchiita mabasa ekuvaka muzvikepe, matangi, mapaneru uye maprofiles nepo CSM ichibata shanduko nebasa repamusoro rakaipoteredza.

Kana basa rejira riri rekushongedza kana kudzora ngura, iro ibasa rejira repamusoro, kwete remachira anorema - jira reshinda diki (20–90 g/m²) riripo kuti rigadzire pamusoro wakapfuma neresin inovanza simba rayo guru.

Kugadzira laminate: muenzaniso wakashanda

Heino maitiro anoita mabasa acho kuita murwi.

1. Kuburitswa kwemould / gel jasi— nzvimbo yekunze yakapedzwa.
2. Chifukidziro chepamusoro(zvakanaka, 20–90 g/m² kirasi) — inogadzira mukati memukati mune resin yakawanda kuitira kuti shinda dzakaoma dzisabate nzvimbo yakachengetwa.
3. CSM liner plies— kuvaka ukobvu hwe liner ne isotropic, ine resin yakawanda.
4. Kufamba-famba kwakarukwa— takura mutoro wechimiro munzira mbiri dzejira.
5.CSM— sunga jira rakarukwa rinotevera woenzanisa pepa rakarukwa.
Dzokorora 4–5 kuti usvike pakukora kwedhizaini; vhara neCSM apo divi rekumashure rinoonekwa.

Mukubatanidza pultrusion ne filament, pfungwa imwe chete inoshanda kune vatambi vakasiyana: machira ekusona e veil combo anogona kutsiva machira akasiyana e veil-plus-mat, uye kufamba zvakananga kunotsiva jira rakarukwa sechinotakura fiber chinoenderera mberi.

Mibvunzo Inowanzo bvunzwa

Ndeipi jira rakasimba, rakachekwa kana kuti rakarukwa?

Kurema kweyuniti imwe neimwe, kurongeka kwakarukwa — machira ayo anoenderera mberi anotakura mutoro pamwe chete nemaaxes ejira, nepo CSM ichiparadzira machira mapfupi kumativi ese. Asi kuenzanisa kunongoreva chimwe chinhu chine huremu hwakaenzana, huwandu hwakaenzana hwe resin uye divi rimwe chete remutoro. Mukuita, mubvunzo hausi wekuti: CSM inopa kufukidza, kubatana uye basa repamusoro, kurongeka kwakarukwa kunopa simba rekutungamira, uye akawanda ma lay-up anoshandisa zvese zviri zviviri.

Ndingashandisa CSM nerukwa pamwe chete here mulaminate imwe chete?

Ehe — kuchinjanisa ndiwo maitiro akajairika ekurongedza nemaoko nekuti chimwe nechimwe chinofukidza kusasimba kwechimwe: CSM inogadzirisa kukweshana kwakaoma, inovandudza kubatana kwepakati pezvikamu uye inononoka kutevedza mvura iri kufamba-famba; kufamba-famba kwakarukwa kunotakura mutoro. Mati ekubatanidza anosona maviri aya kuita jira rimwe chete kana nguva yekurongedza ichikosha kupfuura kudzora ply-by-ply.

Ko rudzi rwebinder muCSM runokosha here?

Ehe. Zvisungo zveupfu ne emulsion zvinonyungudika mu resin panguva yekuumba, izvo zvinoita kuti CSM ienderane uye ibatane — asi zvinosungawo mat kune masisitimu e resin anoenderana uye maitiro. Kana maitiro ako ari ekupinza, kupwanya kana kumonera pane kurongedza nemaoko, mat isina kumonera inobvisa danho rekunyungudika zvachose.
