Analyses Of Pultruded Polyester/ E-Glass Composites Subjected To Environmental Degradation, Cameron Bosley

Electronic Theses and Dissertations

This paper evaluates the response of experimental mold releases for a pultruded glass fiber reinforced polymer (gfrp). The initial assessment criteria include comparisons between pull forces and surface appearances for each mold release. Composites fabricated using experimental mold releases that exhibited acceptable properties for both were used for further mechanical characterization that included environmental aging for two different exposure lengths (500 hours and 1000 hours) in five different environments: UV, bleach, hydrochloric acid, distilled water at 125â°f, and room temperature salt water. Three-point flexural bending and short beam strength tests were undertaken to determine the effects these environments would have …
