中温固化树脂／碳布复合材料工艺性能研究

采用树脂的粘度-温度曲线、凝胶时间-温度曲线、DSC法确定了树脂的固化工艺.比较了溶液法和热熔法制备的预浸料复合材料力学性能.结果表明,热熔预浸料复合材料湿热性能高于溶液预浸料.对复合材料断面进行扫描电镜分析,断面的纤维和树脂粘接良好.

Study on Processability Properties of Resin /Carbon Cloth Composite Curing at Moderate Temperature

It has been reported in this paper that the curing process parameters of the resin were determined by the methods of the curves of viscosity-temperature and gel time-temperature as well DSC of the resin.The mechanical properties of the composites made of the prepregs impregnated in both solvent and hot-melt methods were compared.The results showed that the "hot-wet" environments-resistance of the letter was better than the former.The analysis of the SEM on the fracture surfaces of composite showed that bonding between the fiber and resin of composite was good.
