将环氧树脂固化实验打造为综合设计性实验
|
摘要
讨论了将实验"环氧树脂固化"验证性实验改造为综合性设计实验的内容和过程,采用拉-挤成型法制备连续纤维增强环氧树脂复合材料,并进行力学性能测试;讨论连续纤维的分布状况变化对复合材料力学性能的影响趋势。通过本综合性设计实验,学生能够熟练掌握拉-挤成型法制备纤维增强热固性树脂基复合材料的原理及方法,提高了学生的综合实验技能,激发了学生对科学研究的兴趣。
In this paper, the content and process of transforming the validation experiment "epoxy resin curing and performance test" into a comprehensive design experiment were discussed, and the continuous fiber reinforced epoxy resin composite was prepared by pull-extrusion molding method, and the mechanical properties were tested. Then the effects of the different distribution of fibers in the resin matrix on the mechanical properties of the composites were discussed. Through this comprehensive design experiment, students can master the preparation principle and method of fiber reinforced thermosetting resin matrix composites, improve their comprehensive experimental skills, and stimulate their interest in scientific research.
