Mpweya wa carbon fiber composite material (CFRP), pogwiritsa ntchito phenolic resin monga matrix resin, imakhala ndi kutentha kwakukulu, ndipo katundu wake sangachepetse ngakhale pa 300 ° C.

CFRP imaphatikiza kulemera kwake ndi mphamvu, ndipo ikuyembekezeka kugwiritsidwa ntchito kwambiri pamagalimoto am'manja ndi makina amakampani omwe amatsata zofunikira zochepetsera thupi komanso kupanga bwino. Komabe, CFRP yochokera pazambiri-cholinga epoxy utomoni ali ndi vuto kukana kutentha ndipo sangathe kukwaniritsa zosowa zosiyanasiyana za makasitomala. Kutentha kosagwira kutentha kwa CFRP ndi Mitsubishi Chemical's epoxy resin monga maziko a 100-200 ℃, ndipo chatsopanocho chinapangidwa nthawi ino ndi phenolic resin monga maziko ake ali ndi kukana kutentha kwakukulu, ndipo katundu wake sali ngakhale kutentha kwakukulu kwa 300 ℃. kuchepetsa.

Kuwonjezera pa makhalidwe a mkulu matenthedwe madutsidwe, kuuma mkulu, ndi kulemera kuwala, CFRP nayenso bwinobwino anapereka mkulu kutentha kukana, amene akuyembekezeka kuthandiza makasitomala kuthetsa mavuto amene anali ovuta kuthetsa kale. Tsopano makasitomala ena aganiza zoyesera ndipo alimbikitsanso kugwiritsa ntchito zinthuzo mundege, magalimoto, mayendedwe anjanji, mafakitale ndi magawo ena mtsogolo.
