研制了一种耐低温耐腐蚀树脂基复合材料,记为S2/EpD。该材料在低温-40℃的两种氟碳化合物(记为Fa、Fb)里分别浸泡1000h后,其层间剪切强度保持率均大于85%,且复合材料外观无显著变化。S2/EpD复合材料单向环在Fa氟碳化合物里浸泡1000h后,层间剪切强度保持率为86.4%;在Fb氟碳化合物里浸泡1000h后,层间剪切强度保持率为90.3%。S2/EpD复合材料采用自制环氧/酸酐配方,以高强玻璃纤维(S2)为增强材料,通过湿法纤维缠绕成型制作。
Developed a low temperature corrosion-resistant resin-based composites, denoted S2 / EpD. After being soaked in two fluorocarbons (denoted as Fa and Fb) at low temperature of -40 ° C for 1000h, the interlaminar shear strength retention rates of the two materials all exceeded 85%, and the appearance of the composites did not change significantly. After unidirectional ring of S2 / EpD composite was immersed in Fa fluorocarbon for 1000 h, the interlaminar shear strength retention was 86.4%. After being soaked in Fb fluorocarbon for 1000 h, the interlaminar shear strength retention was 90.3%. S2 / EpD composites made of self-made epoxy / anhydride formulations, high-strength glass fiber (S2) as a reinforcing material, through the wet-fiber winding production.
