摘要:
Methactylate epoxy resin of 1,1'-bis(4-hydroxyphenyl)cyclohexane (EBCMA)was synthesized and mixed with 40% styrene as a reactive diluent. The structure of EBCMA was characterized by IR and (HNMR)-H-1 techniques. Cured and uncured resins are thermally stable up to about 322-326 degrees C and followed two and three steps degradation reactions, respectively. Jute (J-EBCMASt) and glass(G-EBCMASt) showed respectively 34.5 and 220.9 MPa tensile strength; 32.3 and 101.6 MPa flexural strength; 1.6 and 2.1 kVmm(-1) electric strength and 5.9 X 10(12) and 4.5 X 10(13) ohm.cm volume resistivity. Both the composites showed excellent chemical resistance against harsh environmental conditions. Good thermal, mechanical and electrical properties and good environmental stability of the composites signified their industrial importance in construction, electrical and marine applications.
