The forming fasaha na high yi thermoplastic composites aka yafi dashi daga thermosetting guduro composites da karfe forming fasahar. A cewar daban-daban kayan aiki, shi za a iya raba gyare-gyaren, biyu film gyare-gyaren, autoclave gyare-gyaren, injin jakar gyare-gyaren, filament winding gyare-gyaren, calendering gyare-gyaren, da dai sauransu A cikin wadannan hanyoyin, za mu zabi wasu 'yan more amfani gyare-gyaren hanyoyin da za a ba ka a takaice. Gabatarwa, ta yadda za ku iya samun ƙarin fahimtar abubuwan da ake amfani da su na thermoplastic carbon fiber composites.

1. Biyu film kafa
Sau biyu gyare-gyaren membrane, wanda kuma aka sani da resin membrane infiltration gyare-gyaren, hanya ce da kamfanin ICI ya ƙera don shirya sassa masu haɗaka tare da prepreg. Wannan hanya tana da amfani ga gyare-gyare da sarrafa sassa masu rikitarwa.

A cikin nau'i-nau'i na fim guda biyu, an sanya prepreg da aka yanke a tsakanin nau'i biyu na fim din resin m mai lalacewa da fim din karfe, kuma an rufe gefen fim din da karfe ko wasu kayan. A cikin tsari, bayan dumama zuwa yanayin zafi, ana amfani da wani nau'i na nau'i na nau'i, kuma sassan sun lalace daidai da siffar karfe, a karshe kuma a kwantar da su kuma su yi siffar.

A cikin aikin samar da fim sau biyu, sassan da fina-finai yawanci ana tattara su kuma a shafe su. Saboda nakasar fim ɗin, ƙuntatawar guduro ya fi na ƙaƙƙarfan mold nesa ba kusa ba. A gefe guda kuma, fim ɗin da aka lalata a ƙarƙashin injin zai iya yin matsin lamba iri ɗaya a kan sassan, wanda zai iya inganta bambance-bambancen matsa lamba na sassan kuma tabbatar da ingancin samarwa.

2. Pultrusion gyare-gyare
Pultrusion tsari ne mai ci gaba na masana'anta na haɗe-haɗen bayanan martaba tare da sashin giciye akai-akai. Da farko, an yi amfani da shi don kera samfurori masu sauƙi tare da fiber unidirectional yana ƙarfafa sashin giciye mai ƙarfi, kuma a hankali ya haɓaka zuwa samfura masu ƙarfi, fashe da sassa daban-daban na giciye. Haka kuma, ana iya tsara kaddarorin bayanan martaba don biyan buƙatun tsarin injiniya daban-daban.

Yin gyare-gyaren ɓarna shine don ƙarfafa tef ɗin prepreg (yarn) a cikin rukuni na gyare-gyaren pultrusion. Prepreg yana ko dai pultruded da prepreg, ko ciki daban. Hanyoyi na gaba ɗaya sune fiber blending impregnation da foda liquefying gado impregnation.

3. Gyaran Matsi
An yanke takardar prepreg bisa ga girman mold, mai tsanani a cikin tanderun dumama zuwa zafin jiki mafi girma fiye da zafin jiki na narkewa na guduro, sa'an nan kuma aika zuwa babban mutu don saurin matsawa mai zafi. Ana kammala zagayowar gyare-gyaren a cikin dubun daƙiƙai zuwa ƴan mintuna. Irin wannan hanyar gyare-gyaren yana da ƙarancin amfani da makamashi, ƙarancin samarwa da yawan aiki. Ita ce hanyar gyare-gyaren da aka fi sani da ita a cikin tsarin gyare-gyare na thermoplastic composites.

4. Yin iska
Bambance-bambancen da ke tsakanin filament winding na thermoplastic composites da thermosetting composites shi ne cewa prepreg yarn (tef) ya kamata a mai tsanani zuwa taushi batu da kuma mai tsanani a lamba batu na mandrel.

Hanyoyin zafi na gama gari sun haɗa da dumama gudanarwa, dumama dielectric, dumama lantarki, dumama hasken lantarki, da sauransu. na electromagnetic kalaman. A cikin 'yan shekarun nan, Laser dumama da ultrasonic dumama tsarin an kuma ɓullo da.

A cikin 'yan shekarun nan, an ɓullo da sabon tsarin iska, wanda ya haɗa da hanyar gyare-gyaren mataki ɗaya, wato, ana yin fiber a cikin yarn prepreg (tef) ta hanyar tafasa gadon liquefaction na thermoplastic resin foda, sa'an nan kuma kai tsaye rauni a kan mandrel; Bugu da ƙari, ta hanyar tsarin dumama, wato, carbon fiber prepreg yarn (tef) yana ba da wutar lantarki kai tsaye, kuma resin thermoplastic yana narkewa ta hanyar lantarki da dumama, ta yadda za a iya raunata zaren fiber (tef) a cikin samfurori; Na uku shi ne yin amfani da mutum-mutumi don yin iska, da inganta daidaito da sarrafa samfuran iska, don haka ya sami kulawa sosai.
