Girazi fiber reinforcement zvinhu, sengeContinuous filament mat (CFM)uyeakachekwa tambo mat (CSM), tamba mabasa akakosha mukugadzira mubatanidzwa. Nepo ese ari maviri achishanda sezvinhu zvekutanga zve-resin-based process, maitiro avo ekugadzira uye nzira dzekugadzira zvinosiyana zvakanyanya, zvichitungamira kune akasiyana mabhenefiti ekuita mumaindasitiri ekushandisa.
1. Fiber Architecture uye Manufacturing Process
Continuous filament mat inoumbwa nezvakango tenderera asi zvisingapindiki mafiber bundles, yakasungwa pamwe chete uchishandisa mabhinda emakemikari kana nzira dzemuchina. Kuenderera mberi kwemaitiro emafibhi kunovimbisa kuti mat inochengetedza tambo refu, isina kuparara, ichigadzira network yakabatana. Uku kutendeseka kwechimiro kunobvumira kuenderera mberi kwema filament mats kuti akwanise kumirisana nemakanika zvinobudirira, zvichiita kuti ive yakanakira.high-pressure molding process. Kusiyana neizvi, tambo yakachekwa mat inepfupi, discrete fiber zvikamukugovaniswa zvisina tsarukano uye kusungirirwa nehupfu kana emulsion binders. Iyo discontinuous fibers inoguma mune isina kuomarara chimiro, icho chinoisa pamberi nyore kubata uye kuchinjika pamusoro pesimba mbishi.
2. Mechanical uye Processing Performance
Iyo inoenderera mberi fiber alignment muCFM inopaisotropic mechanical propertiesnekuwedzerwa simba rekusimba uye kuramba kune resin washout. Izvi zvinoita kuti kunyanya kukodzerayakavharwa-mold maitirokufanana neRTM (Resin Transfer Molding) kana SRIM (Structural Reaction Injection Molding), apo resin inofanira kuyerera zvakafanana pasi pekumanikidzwa pasina kubvisa fiber. Kugona kwayo kuchengetedza dimensional kugadzikana panguva resin infusion inoderedza kuremara mune yakaoma geometries. Chepped strand mat, zvisinei, inokunda mukatikukurumidza resin saturationuye kuenderana nezvimiro zvisina kujairika. Iwo mapfupi fiber anobvumira kukurumidza kunyorova-kunze uye zvirinani kuburitswa kwemhepo panguva yekugadzika ruoko kana kuvhurika kuumbwa, zvichiita kuti ive sarudzo inosarudzika yezvakareruka, zvisingadhure maapplication senge bathware kana mota mapaneru.
3. Kushandisa-Chaiyo Yakanakira
Continuous filament mats akagadzirirwayepamusoro-performance compositeszvinoda kusimba, senge zvinhu zvemuchadenga kana mablades eturbine yemhepo. Kupokana kwavo kune delamination uye kwepamusoro kuneta kuramba kunovimbisa hupenyu hurefu pasi pemitoro yecyclic. Akachekwa tambo mats, kune rumwe rutivi, akagadziridzwakugadzirwa kwakawandauko kumhanya uye kushanda zvakanaka kwezvinhu zvine basa. Ukobvu hwadzo yunifomu uye kuenderana nemhando dzakasiyana resins dzinoita kuti dzive dzakanakira kuumbwa kwemashizha (SMC) kana kugadzira pombi. Pamusoro pezvo, akachekwa tambo mameti anogona kugadziridzwa mu density uye binder mhando kuti ienderane nemamiriro chaiwo ekurapa, ichipa kuchinjika kune vanogadzira.
Mhedziso
Sarudzo pakati peinoenderera mberi filament mat uye yakachekwa tambo mats inotsamira pakuenzanisa zvimiro zvezvinodiwa, kumhanya kwekugadzira, uye mutengo. Inoenderera mberi filament mats inopa simba risingaenzaniswi kune epamberi macomposites, nepo akachekwa tambo mats anoisa pamberi pekuita zvakasiyana-siyana uye hupfumi mune yakakwirira-vhoriyamu maapplication.
