Kapangidwe kake kali ndi magulu atatu: matrix, reinforcement, ndi zowonjezera, zomwe zili ndi ntchito zomveka bwino.utomoni wa phenolic, imakhala ndi 40%-60%, zomwe zimapangitsa kuti "chigoba" cha chinthucho chikhale cholimba komanso chimapereka kukana kutentha kwambiri, kukana dzimbiri, komanso kumamatira, zomwe zimatsimikiza makhalidwe oyambira a chinthucho. Zipangizo zolimbikitsira, ulusi wagalasi, zimakhala ndi 30%-50%, makamaka ulusi wodulidwa mwachidule (1-5mm m'litali), womwe umagwira ntchito ngati "mipiringidzo yachitsulo" kuti ukhale wolimba komanso wolimba komanso kupewa kusweka kwa chinthucho. Dongosolo lowonjezera limaphatikizapo zinthu zochiritsira, mafuta odzola, zodzaza, ndi zinthu zolumikizira, zomwe zimakhala ndi gawo lonse la 5%-10%, kuonetsetsa kuti ntchito yake ikuyenda bwino.

Phenolic galasi fiber kupanga phalandi chinthu chopangira utomoni chomwe chimapangidwa pogwiritsa ntchito phenolic resin ngati matrix, utomoni wagalasi ngati cholimbikitsira, ndikuwonjezera zinthu zina monga zophikira, mafuta, ndi zodzaza, kudzera munjira zinazake kuphatikizapo kusakaniza, kuyika, ndi kuumitsa. Chili ndi ubwino wowirikiza wa phenolic resin ndi utomoni wagalasi. Phenolic resin ili ndi kukana kutentha, kukana dzimbiri, komanso kutchinjiriza, pomwe utomoni wagalasi umawongolera kwambiri mawonekedwe a makina a chinthucho, monga mphamvu, kuuma, ndi kukana kukhudza. Zinthuzi zimatha kukonzedwa m'mawonekedwe osiyanasiyana ovuta kudzera munjira zopangira utomoni monga kupondereza utomoni ndi kupangira jekeseni, ndipo zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana monga zamagetsi, zamagalimoto, makina, ndi mankhwala. M'mafakitale amagetsi, chingagwiritsidwe ntchito popanga ma switch oteteza kutentha, sockets, ndi motor; m'mafakitale agalimoto, chingagwiritsidwe ntchito kupanga zinthu zosawonongeka monga ma clutch faces ndi ma brake pads; m'mafakitale, chimatha kupanga zinthu zomangira monga magiya ndi ma bearing cages. Njira yake yopangira utomoni ndi yosavuta, kupanga kwake ndi kwakukulu, ndipo zinthu zake zimakhala ndi kukhazikika kwabwino komanso mtengo wake ndi wokwera. Ndi zipangizo zamakono zomwe zimagwira ntchito bwino kwambiri, zomwe zimatha kukwaniritsa zofunikira zosiyanasiyana pakugwira ntchito kwa zipangizo zosiyanasiyana m'mafakitale osiyanasiyana ndikupereka chithandizo chodalirika cha zipangizo zofufuzira, kupanga ndi kupanga zinthu zina zokhudzana nazo.
