Abstract : Thermogravimetric analyses were made on Resinox 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 investigated. Kinetic constants were calculated for the materials from thermogravimetric analysis results and an empirical method of kinetic calculations is discussed. The thermal endurance limit of Resinox glass laminate was also calculated. Differential thermal analyses were carried out on Resinox and Epon laminates and theoretical kinetic relationships were used to facilitate their interpretation. This technical documentary report has been reviewed and is approved. p5
