With the increase in ha content, the flexural strength and flexuremodulusof composites had been greatly increased and the tensile strength of composites had only a little change.
随着复合材料中ha含量的增加，材料的弯曲强度、弯曲模量有大幅提高，而材料的抗拉强度即韧性降低不大。

The flexuremodulus test results shows, the flexuremodulusof the middle layer group PMMA strengthening material has no obvious difference with the same thickness group (P>0.05);
