Abstract

Composites are the most important materials in transportation and automotive sector. In the present work the composites were prepared by bus body building method known as hand layup technique. Using this technique the polymers namely epoxy resin and polyester resin were applied seperately on chopped strand matt powdered type glass fibres and compared. Sandwich laminate panels were prepared and investigated the nature of moisture absorbance on 60 days. The properties were found to be higher in moisture absorbance for polyester resin compared to epoxy resin. The elimination of resin accessories such as gelcoat, pva, wax, accelerator in epoxy resin, improved in proportion and percentage of epoxy resin with hardener as (90:10) and 70%, glass fiber consumption of 30%, and at last the standard fixed ratio of 1:1.50:2 for 450:300:225 category of three different combined stack grades of chopped strand matt powdered type glass fibre were the only reasons for the less moisture absorbance of epoxy resin than polyester resin in these observations.
