ＬＰ－１５聚酰亚胺是一种不含ＭＤＡ的新型ＰＭＲ聚酰亚胺树脂。本文研究了ＬＰ－１５复合材料的耐热氧化稳定性。结果表明，ＬＰ－１５复合材料在２８０℃以下具有良好的热氧化稳定性以及较高的性能保持率，可在２８０℃以下替代ＰＭＲ－１５长期使用。
LP-15 polyimide is a new MDA-free PMR polyimide resin. In this paper, the thermal stability of LP-15 composites was investigated. The results show that LP-15 composite has better thermal oxidation stability and higher performance retention below 280 ℃, which can be used as a long-term alternative to PMR-15 below 280 ℃.
