Nzira Dzakakosha Dzekuwedzera Simba reKubatana kweInterfacial muFiberglass Composites

Muzvinhu zvakasanganiswa, mashandiro e fiberglass sechinhu chakakosha chekusimbisa anonyanya kuenderana nekugona kwekubatanidza pakati pe fiber ne matrix. Simba rekubatana uku kunosarudza kugona kwekufambisa kushushikana kana fiber yegirazi iri pasi pemutoro, pamwe nekugadzikana kwe fiber yegirazi kana simba rayo rakakwirira. Kazhinji, kubatana pakati pe fiberglass ne matrix hakuna kusimba, izvo zvinotadzisa kushandiswa kwe fiberglass muzvinhu zvakasanganiswa zvine simba guru. Nokudaro, kushandisa nzira yekuvhara saizi ye agent kuti uvandudze chimiro che interfacial uye kusimbisa kubatana kwe interfacial inzira yakakosha yekuvandudza mashandiro e glass fiber composites.

Chinhu chinoumba saizi inoumba denderedzwa remamorekuru pamusoro pefiberglass, izvo zvinogona kuderedza kushushikana kweinterfacial, zvichiita kuti fiberglass surface ive inonyungudika zvakanyanya kana kuti inonyungudika zvakanyanya kuti ienderane ne matrix. Semuenzaniso, kushandisa saizi ine mapoka anoshanda nemakemikari kunogona kugadzira zvisungo zvemakemikari nefiberglass surface, zvichiwedzera simba reinterfacial bond.

Tsvagiridzo yakaratidza kuti zvinhu zvinoumba saizi ye nano-level zvinogona kufukidza pamusoro pe fiberglass zvakaenzana uye kusimbisa kubatana kwemakemikari nemakemikari pakati pe fiber ne matrix, nokudaro zvichivandudza zvinobudirira hunhu hwe fiber. Panguva imwe chete, fomura yakakodzera ye saizi inogona kugadzirisa simba repamusoro pe fiber uye kuchinja kunyorova kwe fiberglass, zvichiita kuti fiberglass ibatane zvakasimba pakati pe fiber nezvinhu zvakasiyana zve matrix.

Maitiro akasiyana ekuputira anewo simba guru pakuvandudza simba rekubatana kwemukati memuviri. Semuenzaniso, purasitiki-assisted coating inogona kushandisa ionized gas kurapagirazi faibhapamusoro, kubvisa zvinhu zvipenyu netsvina, kuwedzera kushanda kwenzvimbo, uye nokudaro kuvandudza kubatana kwechinhu chinoisa saizi pamusoro pefaibha.

Zvinhu zvematrix pachazvo zvine basa rakakosha mukubatana kwemukati megirazi. Kugadzira ma matrix formulations matsva ane hukama hwakasimba hwemakemikari kune fibers dzegirazi dzakagadziriswa kunogona kutungamira mukuvandudzwa kukuru. Semuenzaniso, ma matrix ane huwandu hwakawanda hwemapoka anogamuchira anogona kuumba ma covalent bonds akasimba ne saizi agent pamusoro pe fiber. Uyezve, kugadzirisa viscosity uye flow properties yezvinhu zvematrix kunogona kuve nechokwadi chekuti fiber bundle inopinda zviri nani, zvichideredza ma voids uye zvikanganiso pa interface, izvo zvinowanzo kukonzera kusasimba.

Maitiro ekugadzira pachawo anogona kugadziriswa kuti awedzere kubatana kwemukati memadziro.kuisirwa kwevacuumkanakuumbwa kwe resin transfer (RTM)inogona kuve nechokwadi chekuti mvura inonyoroveswa zvakaenzana uye zvakakwanamagirazi egirazine matrix, zvichibvisa mapombi emhepo anogona kushayisa simba chisungo. Pamusoro pezvo, kushandisa kumanikidzwa kwekunze kana kushandisa tembiricha inodzorwa panguva yekupisa kunogona kukurudzira kubatana kwepedyo pakati pefiber ne matrix, zvichikonzera mwero wepamusoro wekubatanidza uye interface yakasimba.

Kuvandudza simba rekubatanidza magirazi fiber composites inzvimbo yakakosha yekutsvaga ine mashandisirwo akakosha. Kunyange hazvo kushandiswa kwezvinhu zvinoisa saizi uye maitiro akasiyana-siyana ekuputira ari iwo musimboti wekuedza uku, kune dzimwe nzira dzakawanda dziri kuongororwa kuti dziwedzere kushanda zvakanaka.
