Filament Winding Precision Resin Impregnation System

摘要

This report presents the results of a program to develop and evaluate a precision resin impregnation system. The program objective was to develop a resin impregnator capable of consistently wetting S-glass, Kevlar and graphite roving with resin controlled within plus or minius 2% by weight. The tests conducted demonstrate the ability of the developed equipment to meet resin content control objectives. The effect of the process variables of fiber temperature, resin temperature and winding speed on impregnation quality were evaluated. Short beam shear tests and microstructure analysis were the primary evaluation tests conducted. (Author)
