OPTIMASI KEKUATAN TARIK KOMPOSIT POLYESTER DIPERKUAT SERAT SISAL DENGAN FILLE…

Composites is an engineering material which is made from combination of two or more different materials into a new material with new properties. The aim of this research is to investigate optimum composition of sisal fiber reinforced sawdust sengon filled polyester composites on the tensile strength using respon surface methodology. The testing of tensile strength is based on ASTM D 3039 stand…
