简支梁冲击强度

结果显示，苯乙烯类树脂具有最好的增韧效果，当其含量达到40份时，能使PS体系的简支梁缺口冲击强度达到42.1kJ/m2。

Experimental results indicated that styrene resins have the best toughening effect and the notched Charpy impact strength was up to 42.1 kJ / m 2 when its content is 40 phr .

在β成核剂质量分数为0.6%时，β晶相对含量最高，简支梁缺口冲击强度和断裂伸长率达到最大值，皆为纯PP的2倍多。

When 0.6 % β nucleating agent was added , the relative β crystalline fraction was the highest , so the Charpy notched impact strength and the elongation at break came up to the highest level , being more than two times of that of pure PP.

研究表明，纳米SiO2质量分数为4%的复合材料性能提高较为明显，其中简支梁缺口冲击强度提高51.3%，断裂伸长率提高47.3%，弹性模量提高23.8%；

The results show that the properties of composite material ( mass fraction of SiO_2 is 4 % ) are improved obviously , the impact strength breakage elongation and elastic modulus of the composites are improved by 51.3 % , 47.3 % and 23.8 % , respectively .

材料力学性能优异，拉伸强度和简支梁缺口冲击强度分别达104MPa和6.1kJ/m2。

The tensile and Charpy notched impact strength of the sample were 104 MPa and 6.1kJ / m2 , respectively .
