notched impact strength

Study on Influencing Factors of Notched Impact Strength of PC/ ABS Blends System

PC/ABS共混体系缺口冲击强度影响因素的研究

After ultraviolet irradiating, the Young's modulus and tensile yield strength of HDPE are increased; its elongation at break and notched Izod impact strength are decreased.

紫外辐照后，HDPE的杨氏模量和拉伸屈服强度提高，但断裂伸长率和缺口冲击强度下降。

Results indicated that the integrated mechanical property of HDPE/ E-TMB blends was best with notched izod impact strength increasing 5.65 times, retention rates of tensile yield strength and flexural modulus being respectively 90.8% and 73.7% when elastomer content of E-TMB was 44%.

结果表明，当E-TMB中弹性体含量为44%时，共混物的综合力学性能最好，悬臂梁缺口冲击强度是HDPE的5.65倍，拉伸屈服强度和弯曲弹性模量保留率分别为90.8%和73.7%；

Although the addition of PTFE causes a decrease in notched impact strength of the blends, as compared to pure PA, the absorbed water has little effects on the notched impact strength of the blends.

两种共混物的冲击强度比纯PA明显降低，但是吸收水对两种共混物冲击强度的影响不显著。

TEM and SEM analysis showed that the phase structure of AEMS and AOMS were co-continue structure and the toughening machenism was severe shear yielding when the blends reached their highest notched Izod impact strength.

TEM和SEM分析表明，缺口冲击强度达到最高值的AEMS和AOMS，其相结构为近连续相结构，增韧机理为剪切屈服机理。
