Resin Transfer Molding process (RTM)
1. Tsanangudzo yenzira: Mafibhi akaomeswa akaiswa muhutu hwezasi, iyo inogona kunge yakagara yakamanikidzwa kuita kuti mafibhi aenderane nechimiro chechimiro sezvinobvira uye kusungirirwa zvakasimba; ipapo, mold yepamusoro inogadziriswa pazasi kuti iite mhango, uye ipapo resin inobaiwa mugomba. Vacuum-inobatsira resin jekiseni uye kupinza kwemafiber, inozivikanwa seVacuum-Assisted Resin Injection (VARI), inowanzoshandiswa. Kana iyo fiber infiltration yapera, resin introduction valve yakavharwa uye iyo composite inorapwa. Jekiseni resin uye kurapa kunogona kuitwa pamhepo tembiricha kana pasi pemamiriro ekupisa.
2. Kusarudzwa kwezvinhu:
Resin: kazhinji epoxy, polyester, polyvinyl ester uye phenolic resin, bismaleimide resin inogona kushandiswa pakupisa kwakanyanya.
Fiber: hapana chinodiwa. Sewn fiber inonyanya kukodzera kuita uku, nekuti mukaha uripo pakati pefiber bundle unobatsira kuendesa resin; kune dzakanyanya kugadzirwa fiber dzinogona kukurudzira resin kuyerera
Core material: cellular foam haina kukodzera, nekuti masero euchi achazadzwa neresin, uye kudzvanywa kuchaitawo kuti furo riputsike.
3. zvakakosha zvakanakira:
(1) Yakakwira fiber vhoriyamu chikamu, yakaderera porosity
(2) Hutano nekuchengetedzeka, yakachena uye yakarongeka nharaunda yekushanda sezvo resin yakavharwa zvachose.
(3) Kuderedza kushandiswa kwebasa
(4) Mativi ekumusoro uye ezasi ezvikamu zvemaitiro akaumbwa akaumbwa, izvo zviri nyore kune zvinotevera kurapwa kwepamusoro.
4. Kukanganisa kukuru:
(1) Zviumbwa zvinoshandiswa pamwe chete zvinodhura, zvinorema uye zvakati wandei kuitira kuti zvikwanise kukurira dzvinyiriro huru.
(2) inogumira pakugadzirwa kwezvikamu zvidiki
(3) Nzvimbo dzisina kunyorova dzinogona kuitika nyore, zvichikonzera kuwanda kwezvimedu
5. Mashandisirwo akajairika: diki uye yakaoma space shuttle uye zvikamu zvemotokari, zvigaro zvechitima.
