高分子材料力学性能测试综合实验是高分子材料与工程专业学生的专业综合实验课程中的重要实验项目。在分析专业综合实验课程教学大纲的基础上,结合实验课程教学改革实践,提出了新的高分子材料力学性能测试综合实验教学方案。在学生完成塑料增韧配方设计实验的前提下,结合实验配方对增韧塑料的拉伸强度,断裂伸长率以及冲击强度进行综合分析,从而找出拉伸强度,断裂伸长率及冲击强度随增韧剂的变化规律,进而使学生真正理解塑料增韧机理,掌握塑料增韧配方设计思想。
Mechanical properties of polymer materials test Comprehensive experiment is a major experimental project of professional comprehensive experimental course of polymer materials and engineering students. Based on the analysis of the teaching outline of the comprehensive experimental course of the specialty and the practice of teaching reform in the experimental course, a new comprehensive experimental teaching plan for the mechanical properties testing of the polymeric material is put forward. Tensile strength, elongation at break and impact strength of the toughened plastic were comprehensively analyzed with the experimental formula on the premise of students completing the plastic toughening formula design experiment to find out the tensile strength, elongation at break and impact strength With the law of toughening, and then to enable students to truly understand the plastic toughening mechanism, master plastic toughening formula design.
