一、前言作者于1986年第1期已介绍了耐热耐蚀复合材料,并谈及碳纤增强新酚Ⅱ型树脂、仿Xylok 225及聚苯硫醚在<120℃的31%HC1、50%H_2SO_4·5%NaOH和30%H2CrO_4溶液中的腐蚀试验。试验结果表明聚苯硫醚的耐蚀性最好,即使在强氧化性介质中,经受500小时的腐蚀,弯曲强度保留值仍达98.5%,其他两种不耐蚀。但在前三种介质 I. INTRODUCTION The author introduced the heat-resisting and anticorrosive composite material in the first period of 1986, and also talked about the carbon fiber-reinforced new phenol type II resin, imitation Xylok 225 and polyphenylene sulfide in 31% HC1 <120 ℃, 50% H_2SO_4 · 5% NaOH and 30% H2CrO_4 solution corrosion test. The results show that the best corrosion resistance of polyphenylene sulfide, even in a strong oxidizing medium, after 500 hours of corrosion, the retention of the flexural strength still reached 98.5%, the other two are not corrosion. But in the first three media
