Kuumbwa kwayo kune zvikamu zvitatu: matrix, reinforcement, uye additives, zvine mabasa akajeka. Zvinhu zvematrix,resin yephenolic, inoumba 40%-60%, ichiumba "skeleton" yechigadzirwa ichi uye ichipa kudzivirira kupisa kwakanyanya, kudzivirira ngura, uye kunamira, zvichiratidza hunhu hwechinhu chacho. Chigadzirwa chekusimbisa, fiber yegirazi, chinoumba 30%-50%, kazhinji fibers dzakapfupika (1-5mm pakureba), dzinoshanda se "simbi" kuti dzivandudze simba rekusimba uye kusimba kwechimiro uye kudzivirira kuputsika kwechinhu. Sisitimu yekuwedzera inosanganisira zvinhu zvinogadzirisa, mafuta, zvinozadza, uye zvinobatanidza, zvine huwandu hwe5%-10%, zvichivimbisa kugadziriswa uye kushanda zvakanaka.

Phenolic girazi fiber molding compoundchinhu chinoumbwa nekushandisa phenolic resin sematrix, girazi fiber sekusimbisa, uye kuwedzera zvimwe zvinhu zvakaita sema curing agents, mafuta ekuisa muchimiro, uye zvinozadza, kuburikidza nemaitiro chaiwo anosanganisira kusanganisa, kuisa mudumbu, uye kuomesa. Ine mabhenefiti maviri ephenolic resin negirazi fiber. Phenolic resin ine simba rakanaka rekudzivirira kupisa, kuramba ngura, uye kuputira, nepo girazi fiber richivandudza zvakanyanya hunhu hwemuchina wechinhu ichi, senge simba, kuomarara, uye kuramba kukanganiswa. Chinhu ichi chinogona kugadziriswa kuita maumbirwo akasiyana-siyana akaomarara kuburikidza nemaitiro ekuumba akadai sekumanikidza kugadzira uye kupinza injection, uye chinoshandiswa zvakanyanya muminda yakawanda senge magetsi, mota, michina, uye makemikari maindasitiri. Muminda yemagetsi, inogona kushandiswa kugadzira maswichi ekudzivirira kupisa, masoketi, uye zvikamu zvemota; mumunda wemotokari, inogona kushandiswa kugadzira zvikamu zvisingapfeki senge clutch faces uye brake pads; mumunda wemichina, inogona kugadzira zvikamu zvechimiro senge magiya nemabheyaringi. Maitiro ayo ekuumba ari nyore, kushanda kwayo kwakakwira, uye zvigadzirwa zvayo zvine kugadzikana kwakanaka uye mutengo unonzwisisika. Icho chinhu cheinjiniya chine mashandiro akanaka kwazvo, chinogona kusangana nezvinodiwa zvakasiyana-siyana zvekushanda kwezvinhu zvemaindasitiri akasiyana uye kupa rutsigiro rwakavimbika rwezvinhu zvekutsvaga nekugadzira nekugadzira zvigadzirwa zvine chekuita nazvo.
