Title

Affordable Composites Using Renewable Materials

Abstract

Bio-based composite products are finding widespread applications due to their low cost and environmental acceptability. Development of new bio-based raw material and automated composite manufacturing is the focus of the present study. Pultrusion is the fastest and the most cost-effective composite manufacturing processes, and is well suited for high volume production for structural applications. with growing opportunities to use pultruded composites, the development of cost effective pultrudable resin system is of great interest. A novel soy-based epoxy resin namely epoxidized allyl soyate is synthesized at the University of Missouri-Rolla. This resin forms co-polymers with the base Shell Epon epoxy resin in varied proportions to yield a family of polymeric networks. Glass fiber reinforced composite specimens are manufactured using a Durapul 6000 Labstar Pultrusion machine. The lubricity of soy-based resin significantly reduces the pull force. Mechanical tests show that pultruded composites with soy-based co-resin systems possess comparable or improved structural performance characteristics such as flexural strength, modulus and impact resistance.
