Glass Reinforced-Diallylbisphenol/Maleimide Composites with Modified Interphases

Abstract

A silane coupling agent, based on the reaction between gamma aminopropyltrethoxysilane (APS) and maleic anhydride (MA), was prepared. The coupling agent, maleamidopropylsilane (MAPS), was chemisorbed onto E-glass cloth. TGA analysis of the treated glass cloth showed 0.8% weight loss (silane loading), when heated to 700 degree C in an air atmosphere. The treated glass cloths were used in the fabrication of composite laminates having approximately 60 + or - 1 wt% glass reinforcement, with the matrix being a thermosetting system based on diallylbisphenol (DAP) / bismaleimide (BMI). DMTA analysis of the cured composite laminates showed unexpected 10-20 GPA increased in the modulus and a 30-40 deg C increase in the Tg for the treated versus untreated glass cloths.
