초록
In this study, the effect of applied load and sliding speed on friction and wear characteristics of side plate materials of FRP ship, which were composed of glass fiber and unsaturated polyester resin composites(GFRP composites), were investigated at ambient temperature by pin-on-disc friction test. The cumulative wear volume, friction coefficient and wear rate of this materials against SiC abrasive paper were determined experimentally. The cumulative wear volume tended to increase nonlinearly with increase of sliding distance and depended on applied load and sliding speed for this composites. The friction coefficient of GFRP composites were increased as applied load at same sliding speed in wear test increased. It could be verified by SEM photograph of worn surface that major failure mechanisms were microfracture, deformation of resin, cutting and cracking.
Abstract

The cumulative wear volume tended to increase nonlinearly with increase of sliding distance and depended on applied load and sliding speed for this composites. The friction coefficient of GFRP composites were increased as applied load at same sliding speed in wear test increased. It could be verified by SEM photograph of worn surface that major failure mechanisms were microfracture, deformation of resin, cutting and cracking.
