HA porous prepreg reinforced PMMA composites were prepared byimpregnation method and in situ mass polymerization. Viscosity of PMMAprepolymer and temperature of in situ mass polymerization were critical to thepreparation of composites.

• HA多孔坯体增强有机玻璃(PMMA)复合材料可以采用坯体预浸渍PMMA低粘度预聚体后,再原位聚合的方法制备,PMMA预聚体的粘度、原位本体聚合的温度是复合材料制备的关键因素。
