摘　　要：为了研究玻璃纤维长度及含量对酚醛泡沫性能的影响,分别将微米级玻纤粉、3mm短切玻纤和6mm短切玻纤按照一定比例添加到酚醛泡沫体系中,利用Instron万能材料试验机,分别测试玻纤增强酚醛泡沫的压缩、拉伸强度,并利用扫描电镜观察酚醛泡沫的微观形貌。结果表明,添加了12%的3mm短切玻纤增强酚醛泡沫压缩性能最好,其压缩强度比纯酚醛泡沫增加了38%;添加了8%的6mm短切玻纤增强酚醛泡沫拉伸性能最好,其拉伸强度比纯酚醛泡沫增加47%;添加了12%的3mm短切玻纤增强酚醛泡沫的阻燃性能最好,其极限氧指数为44.1。In order to study the influence of glass-fiber length and content to the properties of phenolic foams, micro glass-fiber powder, 3mm chopped glass-fibers and 6mm chopped glass-fibers were added into phenolic foams in accordance with some proportion in the paper. Compression and tension properties of glass-fiber reinforced phe- nolic foams were tested by using Instron universal material tester and micromorphology was observed by SEM too. The result shows that compressive properties of phenolic foam were best when the content of glass-fiber is 12%, with a chop length of 3mm, and compression increased 38% than that of pure phenolic foams. Tensile properties of phe- nolic foam were best when the content of glass-fiber is 8%, with a chop length of 6mm, and tension increased 47% than that of pure phenolic foams. Flame retardant properties of phenolic foam was best when the content of glass-fi- ber is 12% , with a chop length of 3mm, and the LOI of phenolic foam was 44. 1.
