Epoxy/Phenol resins have been widely used in many engineering areas due to their excellent properties in insulation, adhesion, chemical resistance and moisture absorption. However, they had a relatively high coefficient of thermal expansion(CTE) as a drawback. In order to improve the CTE of epoxy/phenol resin system, making composites with glass fiber(GF) has been generally performed. In this study, We tried to restrict the segmental chain motion of matrix resin by modifying the interface between matrix and glass fiber reinforcement. Allylated phenol novolac resin was synthesized and surface treatment of GF was performed. Thermo-properties of the composites were examined by using DSC, TMA, and TGA, respectively and the results were addressed with a viewpoint of interfacial modification. |
