Surface Modified Abaca Fibers: Physico-Mechanical, Morphological and Degradation Properties Evaluation
Abstract: Lignocellulosic fibers are used as cost-cutting fillers in plastics factories. Amid several factors, the ultimate performance of composite ingredients depends on the bond between the matrix resin and the filler, and hence on the quality of the interface. To acquire optimal performance of the end product, adequate interaction between the matrix and the lignocellulosic ingredient is preferred. This is often acquired through surface modification of the matrix or filler. Abaca …
