Pengaruh Komposisi Serat Kelapa terhadap Karakter Dinamis dan Waktu Gesek Bahan Kopling Gesek Kendaraan

Abstract

The aim of this research is to stud y coconut fiber compo site with copp er po wder, fiberglass and ph enolic resin as matrice, due to wear and its hardness. The compo site will be used for clutch, then compare with existing produ ct material. The clutch material consist of coconu t fiber compo site with copper powder, fiberglass and phenolic resin as matrice. Clutch material pressed in a dies with 2 tonag e, with 60 minutes pressing time an d 80 0 C sintering temperature with 40 minute ho lding time. The resul were compo site with co mpo sition coconu t fiber 40 % weight, copper po wder 20 %, fiberglass 2 0 % and phenolic resin 20% its hardness is 4,098 kg/mm2, d ry wearness is 0,14 mm/hr and wet oil wearness is 0,19 mm/hr. The result is near with existing cluthc that ha rdness is 3,974 k g/mm2, dry wearness 0,15 mm/hr and wet wea rness is 0,20 mm/hr.
