Filastik ƙarfafa yankakken carbon fiber
Yankakken carbon fiber
Short-cut carbon fibers suna da ruwa mai kyau, kuma mafi guntu tsawon, mafi kyawun ruwa. Ta hanyar haɗa filayen carbon da aka yanke tare da resin da granulating, sannan yin amfani da gyare-gyaren allura don yin samfura daban-daban, ana iya samun samarwa mai girma.
A cikin masana'antar kayan haɗin gwiwa, bisa ga kewayon amfani da resin matrix, ana buƙatar cewa wakili mai ƙima dole ne ya dace da matrix na ƙarshe yayin aikin masana'anta. A cikin 'yan shekarun nan, ci gaban da aka samu a cikin abubuwan sinadarai na slurry ya haifar da masana'antu don canzawa daga slurries na tushen ƙarfi zuwa slurries na tushen ruwa, yana sa tsarin sikelin ya zama mafi tsabta kuma mafi kyawun muhalli.
Akwai nau'ikan filaye guda huɗu na gajerun zaruruwan carbon: mai siffa, silinda, marar ka'ida, da marasa girma. Ƙarfin ciyar da kayan aikin tagwaye shine: Silinda > Siffar takarda> mara daidaituwa> maras girma (ba a ba da shawarar filaye masu gajeren gajere ba don amfani da kayan aikin tagwaye).
Thermoplastic carbon fiber barbashi tare da PI/PEEK
Daga cikin su, cylindrical short-cut carbon fibers suna da mafi girman buƙatun don albarkatun ƙasa da kayan aiki, amma aikin su kuma ya fi kyau.
A ƙasa akwai wasu ma'aunin fasaha na yankakken fiber carbon ɗin mu don tunani.
