Studies On The Properties Of Pultruded Kenaf Fiber Reinforced Unsaturated Polyester Composites

Kenaf fiber reinforced unsaturated polyester composites (KFRPC) consisting of kenaf fiber (KF) and unsaturated polyester were produced by pultrusion machine, molded into rod specimens. KF and unsaturated polyester was being analyzed and characterized in terms of degradation, physical and mechanic...
