模压石英/酚醛复合材料的力学和热物理性能

Thermal and Mechanical Properties of Moulded Quartz Phenolic Composites

采用力学、热物理等测试方法,研究模压成型石英/酚醛复合材料制品性能,并与模压成型高硅氧/酚醛复合材料制品进行了对比分析。结果表明,模压石英/酚醛复合材料具有较好的力学性能,而且其线胀系数是模压高硅氧/酚醛复合材料的一半,在中低焓值、较低热流、较长烧蚀时间条件下具有很小的热变形。

The properties of moulded quartz phenolic composites are studied by the methods of mechanical and physical tests, comparing with moulded high silica phenolic composites. The result shows that moulded quartz phenolic composite not only has good mechanical property, but also has much more lower thermal deformation in the environ- ment of low enthalpy,low heat flux and long-time ablation as the property of half linear expansion coefficient compa- ring with moulded high silica phenolic composite.
