Fasahar kere -kere na kayan aikin thermoplastic mai ƙarfi mafi girma an dasa shi ne daga kayan haɗin resin na thermosetting da fasahar kera ƙarfe. Dangane da kayan aiki daban -daban, ana iya raba shi zuwa gyare -gyare, gyare -gyaren fim guda biyu, gyare -gyaren autoclave, gyaran jakar injin, filament winding molding, calendering molding, da sauransu. gabatarwa, domin ku sami cikakkiyar fa'ida game da abubuwan da ke tattare da fiber carbon thermoplastic.

1. Yin fim sau biyu
Yin gyare -gyaren membrane sau biyu, wanda kuma aka sani da gyare -gyaren ɓoyayyen membrane, hanya ce da kamfanin ICI ya haɓaka don shirya sassan haɗin tare da prepreg. Wannan hanyar tana da kyau don ƙerawa da sarrafa sassa masu rikitarwa.

A cikin yin fim sau biyu, ana sanya prepreg ɗin da aka yanke tsakanin yadudduka biyu na fim ɗin resin mai canzawa da fim ɗin ƙarfe, kuma an rufe gefen fim ɗin da ƙarfe ko wasu kayan. A cikin tsari, bayan dumama zuwa zafin zafin da ake samu, ana amfani da wani matsin lamba, kuma sassan suna gurɓata gwargwadon ƙirar ƙirar ƙarfe, kuma a ƙarshe sanyaya da siffa.

Yayin aiwatar da yin fim sau biyu, galibin sassan da fina -finan ana kunshe da su. Saboda lalacewar fim ɗin, ƙuntatawar kwararar resin ta yi ƙasa da ta m. A gefe guda, fim ɗin da ya lalace a ƙarƙashin injin zai iya yin matsin lamba iri ɗaya akan sassan, wanda zai iya inganta bambancin matsin lamba na sassan kuma tabbatar da ingancin ƙira.

2. Pultrusion molding
Pultrusion shine ci gaba da ƙera masana'antun bayanan martaba tare da gicciye. Da farko, an yi amfani da shi don ƙera samfura masu sauƙi tare da filayen unidirectional wanda aka ƙarfafa m giciye, kuma sannu a hankali ya haɓaka zuwa samfura tare da m, m da sassa daban-daban masu rikitarwa. Haka kuma, ana iya tsara kaddarorin bayanan martaba don biyan buƙatun tsarin injiniya daban -daban.

Gyara pultrusion shine don haɗa tef ɗin prepreg (yarn) a cikin gungumen ƙirar pultrusion. An riga an yi prepreg kuma an yi prepreg, ko an yi masa ciki daban. Hanyoyin shigar ciki gabaɗaya sune haɗaɗɗen fiber na ciki da foda mai ruɓewa na gado.

3. Molding Matsa lamba
An yanke takardar prepreg gwargwadon girman ƙirar, mai zafi a cikin murhun dumama zuwa zafin jiki mafi girma fiye da narkewar zafin resin, sannan a aika zuwa babban mutu don saurin matsawa da sauri. Yawanci ana yin jujjuyawar juzu'i a cikin dubun sakanni zuwa mintuna kaɗan. Irin wannan hanyar gyare -gyaren yana da ƙarancin kuzarin kuzari, ƙarancin ƙimar samarwa da yawan aiki. Ita ce hanyar da aka fi amfani da ita ta yau da kullun a cikin tsarin kera abubuwan haɗin thermoplastic.

4. Tuddan kafa
Bambanci tsakanin filament winding na thermoplastic composites da thermosetting composites shi ne cewa prepreg yarn (tef) ya kamata a mai da shi zuwa wuri mai laushi da zafi a wurin tuntuɓar mandrel.

Hanyoyin zafi na yau da kullun sun haɗa da dumama madaidaiciya, dumama dielectric, dumama electromagnetic, dumama wutar lantarki, da sauransu. na electromagnetic kalaman. A cikin 'yan shekarun nan, an kuma inganta tsarin dumama laser da tsarin dumama na ultrasonic.

A cikin 'yan shekarun nan, an ƙirƙiri sabon tsarin murƙushewa, gami da hanyar yin gyare-gyaren mataki ɗaya, wato, an sanya fiber ɗin cikin prepreg yarn (tef) ta hanyar tafasa gadon liquefaction na thermoplastic resin foda, sannan a kai tsaye rauni a kan mandrel; Bugu da kari, ta hanyar hanyar samar da dumama, wato, carbon fiber prepreg yarn (tef) ana samun wutar lantarki kai tsaye, kuma an narkar da resin na thermoplastic ta hanyar wutan lantarki da dumama, ta yadda za a iya raunana yarn (tef) cikin samfura; Na uku shine yin amfani da robot don murƙushewa, inganta daidaituwa da sarrafa kayan samfuran iska, don haka ya sami babban kulawa.
