Sebopeho sa yona se na le mekhahlelo e meraro: matrix, matlafatso, le di-additives, tse nang le mesebetsi e hlalositsweng ka ho hlaka. Thepa ya matrix,resin ea phenolic, e ikarabella bakeng sa 40%-60%, e leng se etsang "skeleton" ea thepa le ho fana ka khanyetso ea mocheso o phahameng, khanyetso ea mafome, le ho khomarela, e leng se khethollang litšobotsi tsa motheo tsa thepa. Thepa ea ho matlafatsa, fiber ea khalase, e ikarabella bakeng sa 30%-50%, boholo ba likhoele tse khutšoane (bolelele ba 1-5mm), tse sebetsang joalo ka "li-bar tsa tšepe" ho ntlafatsa matla a ho tsikinyeha le ho kobeha le ho thibela ho robeha ha thepa. Sistimi ea tlatsetso e kenyelletsa li-agent tse phekolang, li-lubricant, li-filler, le li-agent tse kopanyang, ka karolo e felletseng ea 5%-10%, ho netefatsa ts'ebetso le ts'ebetso.

Phenolic khalase faeba bōpa motsoakoke thepa ea ho bopa e entsoeng ka ho sebelisa phenolic resin e le matrix, fiber ea khalase e le matlafatso, le ho eketsa likarolo tse thusang tse kang li-curing agents, li-lubricants le li-fillers, ka mekhoa e itseng ho kenyeletsoa ho kopanya, ho kenya le ho omisa. E na le melemo e 'meli ea phenolic resin le fiber ea khalase. Phenolic resin e na le ho hanyetsa mocheso hantle, ho hanyetsa mafome le ho thibela ho ruruha, ha fiber ea khalase e ntlafatsa haholo thepa ea mechini ea thepa, joalo ka matla, ho tiea le ho hanyetsa tšusumetso. Thepa ena e ka sebetsoa ka libopeho tse fapaneng tse rarahaneng ka mekhoa ea ho bopa joalo ka ho bopa ka khatello le ho bopa ka ente, 'me e sebelisoa haholo masimong a mangata joalo ka indasteri ea motlakase, ea likoloi, ea mechini le ea lik'hemik'hale. Tšimong ea motlakase, e ka sebelisoa ho etsa li-switch tsa ho thibela ho ruruha, li-socket le likarolo tsa enjene; ​​tšimong ea likoloi, e ka sebelisoa ho etsa likarolo tse sa tsofaleng tse kang lifahleho tsa clutch le li-brake pad; tšimong ea mechini, e ka hlahisa likarolo tsa sebopeho tse kang li-gear le li-bearing cage. Mokhoa oa eona oa ho bopa o bonolo, katleho ea eona ea tlhahiso e phahame, 'me lihlahisoa tsa eona li na le botsitso bo botle ba litekanyo le litšenyehelo tse utloahalang. Ke thepa ea boenjiniere e nang le ts'ebetso e ntle e felletseng, e ka fihlelang litlhoko tse fapaneng tsa ts'ebetso ea thepa ea liindasteri tse fapaneng le ho fana ka tšehetso e tšepahalang ea thepa bakeng sa lipatlisiso le nts'etsopele le tlhahiso ea lihlahisoa tse amanang.
