DEVELOPMENT OF IMPROVED HIGH-STRENGTH PREIM PREGNATED MATERIALS FOR FILAMENT WINDING
Abstract
Results from a program which studied the processes used in the manufacture of fiberglass roving and preimpregnated roving made from it are presented. The program was composed of two independent phases. Phase I was a critical analysis of the various steps involved in the manufacture of glass roving from the point of drawing glass filaments to packaging and shipment of the product. The purpose was to establish optimum procedures which would lead to a retention of a greater proportion of the fiber's virgin strength. Test results for eight experimental lots of roving produced for this study include gravimetric measurements and tensile strength. Phase II was a prepreg manufacturing process variable study. A clearer and more quantitative understanding of the effects of preimpregnation manufacturing parameters on the properties of prepreg roving were obtained. Experimental runs were made to investigate seven process variables. The data include gravimetric measurements (volatile, resin content, and weight per linear yard), resin flow, gel time, viscosity index, and tensile strength (both AeroROVE strands and NOL rings.
