高硅氧纤维增强苯并噁嗪树脂复合材料的制备及性能
Preparation and properties of high silica glass fiber reinforced benzoxazine composite①
摘要
Abstract
A novel composite composed of polybenzoxazines and high silica glass fiber was prepared successfully. Thermal prop-erties, curing kinetics and mechanical properties were studied in this paper. The results show that controllable curing window change indistinctively with the increae of heating rate. Curing kinetic parameters of cured mixture were calculated by the methods of Kissin-ger and Crane, and the activation energy is 69.619 kJ/mol, reaction order is 0.95. The tensile strength of composite is 35.5 MPa, compressive strength is 196 MPa, and ablation rate is 0.14 mm /s.关键词
