Stability of Glass Fiber-Plastic Composites
Abstract
Exploratory research was conducted to determine the stages and nature of degradation of glass fiber-plastic composite systems under various environmental conditions. Glass fiber-epoxy structural composites have many characteristics that are desirable in Army materiel; however, they suffer appreciable losses in strength on storage in high humidity-high temperature conditions. A number of mechanical, physical and chemical tests were performed on the individual components in the system and on samples of composites made of these components. It was found that the glass filaments are a reactive component and lose their strength rapidly on direct exposure to water at elevated temperatures. Magnesium is a particularly active component. It was also found that the silane coupling agent that is incorporated in standard commercial glass finishes is a possible reactive component.
