Zinthu zopangidwa ndi ulusi wa kaboni (CFRP), pogwiritsa ntchito phenolic resin ngati matrix resin, zimakhala ndi kukana kutentha kwambiri, ndipo mphamvu zake zakuthupi sizingachepe ngakhale pa 300°C.

CFRP imaphatikiza kulemera kopepuka ndi mphamvu, ndipo ikuyembekezeka kugwiritsidwa ntchito kwambiri pamayendedwe oyenda ndi mafakitale omwe amatsatira zofunikira zochepetsera kulemera komanso magwiridwe antchito opanga. Komabe, CFRP yochokera ku ma epoxy resins ogwiritsidwa ntchito nthawi zonse ili ndi mavuto pakukana kutentha ndipo singakwaniritse zosowa zosiyanasiyana za makasitomala. Kutentha kwa CFRP kosatha kutentha ndi epoxy resin ya Mitsubishi Chemical ngati maziko ndi 100-200℃, ndipo chinthu chatsopano chomwe chapangidwa nthawi ino ndi phenolic resin chifukwa maziko ake ali ndi kutentha kwambiri, ndipo mawonekedwe ake enieni sali ngakhale kutentha kwakukulu kwa 300℃.

Kuwonjezera pa makhalidwe a kutentha kwambiri, kulimba kwambiri, komanso kulemera kopepuka, CFRP yathandizanso kukana kutentha kwambiri, zomwe zikuyembekezeka kuthandiza makasitomala kuthetsa mavuto omwe anali ovuta kuthetsa kale. Tsopano makasitomala ena asankha kuyesa ndipo adzalimbikitsa kugwiritsa ntchito zinthuzo mu ndege, magalimoto, sitima, mafakitale ndi madera ena mtsogolo.
