ANALYSIS OF THERMAL DEGRADATION OF GLASS REINFORCED PHENOLIC AND EPOXY LAMINATES

摘要

Thermo gravimetric analyses were made on Resin ox SC-1008 silicone modified phenolic resin and 75% glass laminate and compared with similar samples of Epon 828 epoxy resin. The effects of atmosphere, sample geometry, inclusion of sized glass fabric, and instrument variables on the degradation kinetics of these materials were investi¬gated. Kinetic constants were calculated for the materials from thermo gravimetric analysis results and an empirical method of kinetic calculations is discussed. The thermal endurance limit of Resin ox glass laminate was also calculated.nDifferential thermal analyses were carried out on Resin ox and Epon laminates and theoretical kinetic relationships were used to facilitate their interpretation,nThis technical documentary report has been reviewed and is approved.
