Development of Improved Environmental Resistant Organic-Reinforced Materials Systems
Abstract
Commercially available matrix resins were identified and a list of resin criteria along with target goals for properties and performance was established. A screening program consisting of dimensional change measurements, water pickup determinations, and TMA curves before and after 24-hour boil was run on a series of castings and/or moldings prepared from the various candidate resins. Several systems emerged which exhibited moisture resistance superior to that of commercially available epoxy systems. Process and cure studies were carried out on glass reinforced laminates which also exhibited excellent moisture resistance. Prepreg parameter and compatibility studies along with tape and laminate fabrication and testing were carried out on the most promising candidate systems. Severe difficulties were finally encountered in achieving both high quality laminates and adequate performance at elevated temperature. The difficulties were identified and alternate means of overcoming these problems were suggested.
