Epoxy Resin Development for Composite Field Repair.
Abstract
An evaluation was conducted to determine the optimum polymer matrix material to be used for composite repair. The material must have room temperature storage and adequate strength at elevated temperatures. Mechanical property degradation due to moisture absorption was also a consideration. Differential scanning calorimetry and dynamic mechanical analyses were performed on the candidate resin systems. Short beam shear and flexural strengths were examined for each system. The most promising resin systems proved to be stable at room temperature in the B-stage condition. These systems incorporated a sterically hindered amine hardener that provided latency. The effects of cloth style on void content and shear properties were also examined. (Author)
