notched izod impact strength

The notched Izod impact strength of alloy increases with the increasing of EMG content in the condition of keeping other mechanical properties.

而随着EM G含量的增加，材料的冲击强度显著提高，且其它的力学性能基本保持不变。

The results show that the addition of mica can enhance the flexural strength, flexural modulus, notched Izod impact strength and heat deformation temperature of the composites;

结果表明：云母可有效提高PP的弯曲强度及模量、悬臂梁缺口冲击强度和耐热性能；

Many round voids which result in stress concentration easily are found on SEM micrographs of fracture surface after heat-treatment, so the notched izod impact strength of the sample decreases.

由热处理后试样冲击断面的SEM照片可见水分挥发留下的空洞，这些空洞容易形成应力集中点，因而导致冲击韧性降低。
