Chinhu chinogadzira firimu ndicho chinhu chikuru chinopinda mugirazi fiber, chinowanzoita 2% kusvika 15% yechikamu chehukuru hwemusanganiswa wemafuta, basa rayo nderekubatanidza fiber yegirazi kuita mabundles, mukugadzira dziviriro yemafibers, kuitira kuti mabundles efiber ave nehupamhi hwakanaka hwekuoma, agglomeration, kuti asangane nezvinodiwa zvinotevera muzvigadzirwa zvegirazi fibers. Zvinhu zvinowanzoshandiswa mukugadzira mafirimu mukugadzirwa kwegirazi fiber infiltrant mapolymers, anosanganisira epoxy resins, polyurethane, polyester, phenolic resins, modified polypropylene dispersions, kana emulsions. Kushanda kwezvinogadzira mafirimu kunonyanya kuenderana nechimiro chemamorekuru uye huremu hwemamorekuru epolymer. Kune chinhu chimwe chete chinogadzira mafirimu, kuomarara kwegirazi faibhainogona kudzorwa nehuremu hwemamorekuru echinhu chinogadzira firimu, uye chinhu chinogadzira firimu chine huremu hwakawanda chichava nekuomarara kwakanyanya kwegirazi fiber, iyo yakakodzera kurapwa pamusoro pechinhu ichi.kusimbisa zvigadzirwa zvegirazi zvakachekwa-chekwa zvethermoplastic, nepo chinhu chinogadzira firimu chine huremu hwakaderera chinokodzera kugadzirwa kweshinda dzinoshandiswa mukumonera nekudhonza. Mapolymer epoxy resin ane mapoka e aliphatic hydroxyl, ether, uye epoxy, uye kune kukwezvana kwakasimba kwemakemikari pakati pemapoka e polar mu epoxy film-forming agents, saka ane hukama hwakanaka uye mhedzisiro yekubatanidza pafiber yegirazi;

Pamusoro pezvo, boka re epoxy riri mu epoxy film-forming agent rinogona kuita ne terminal hydroxyl group, terminal carboxyl group, terminal amino group, nemamwe mapoka anoshanda mumapurasitiki einjiniya akadai sePBT, PET, PA, PC, nezvimwewo, kuti vavandudze simba rekubatanidza pakati pegirazi fiber ne resin. Polyester film-forming agents dzine akawanda ester groups, unsaturated chemical bonds, uye hydrophilic groups mu main chain, uye mashandiro adzo anoenderana nerudzi rwe acid ne alcohol zvinoshandiswa mukugadzirwa kwe polyester uye ratio. Kana base resin iri unsaturated polyester resin, unsaturated double bonds mu polyester film-forming agent inogona polymerize uye cross-link ne double bonds mu base resin kuti igadzire strong chemical bond kana physical entanglement, izvo zvinovandudza interfacial bonding strength. Polyester film-forming agents dzinowanzova ne wetting uye penetration properties dzakanaka uye saka dzinoshandiswa se wetting agents mu pultrusion, winding, spraying, chevron, nezvimwe zvigadzirwa. Mushonga wePolyurethane unoita firimu une chimiro checarbamate chinodzokororwa, kuvapo kwemapoka aya epolar kunoita kuti polyurethane kuenda kugirazi fiber ive nekubatana kwakanaka kwazvo, zvikamu zvakapfava uye zvakaoma zvemamorekuru zvemusanganiswa we elasticity yakanyanya uye abrasion resistance, panguva imwe chete, polyurethane iri muboka re isocyanate inogona kupindirwa ne amino coupling agent uye matrix resin mu chemical reaction, kukurudzira interfacial bonding, kuvandudza mashandiro ezvinhu zvakasanganiswazvigadzirwa.
