FIBER SURFACE MODIFICATION EFFECTS ON TRIBO PROPERTIES OF LUFFA/USP COMPOSITES
Keywords:
Luffa composite , alkali, Ca (OH)2 , silane, wearAbstract
Tribology investigation is one of the most important studies in natural fibers. In this studies using pin - on - disc wear tester the tribological behavior were tested and also mechanical, dry sliding wear behaviors of unsaturated polyester resin (USP), reinforced with natural luffa fibers were experimentally investigated. The chemical, physical and mechanical properties for luffa fiber were studied. For the luffa fiber composites the wear rate differentiations of 2, 3, 4m/s velocity for the 10N, 20N, 30N varying load with the different speed of 318rpm, 477rpm, and 637rpm for the same distance 3000m was determined. Wear rate, hardness, density difference between the NaOH, Trichlorovinyl Silane and Ca (OH)2 treated fiber composites are tabulated. Wear condition in tribological system and the wear mechanism in wear process these both things mainly depends on the analysis of surface topographies of wear components. Surface topographies are interface separation, inclined fracture of fibers, loss of matrix and etc.
