摘    要:通过对普通聚氨酯泡沫塑料和纤维束增强聚氨酯泡沫塑料的准静态拉伸和压缩实验,研究了不同密度和纤维束质量填充比对材料力学性能的影响.实验观察表明,拉伸试件沿垂直载荷方向断裂,呈脆性破坏特征;而压缩破坏试件表面存在着斜向裂开的小块体.实验结果表明,纤维束增强泡沫塑料的应力-应变曲线具有与普通泡沫塑料相同的特征;纤维束能够有效提高材料的模量和强度;材料密度越大,纤维束和树脂基体的体积含量越高,增强效果越好.

关 键 词:玻璃纤维束  泡沫塑料  准静态  拉伸性能  压缩性能

Abstract:The quasi-static tensile and compressive experiments were performed in order to investigate the mechanical properties of conventional polyurethane foam plastics and reinforced ones by glass fiber bundles.The influence of material density and mass content of glass fiber bundles on mechanical properties was analyzed.It is observed from tests that the tensile samples happen to fracture suddenly along perpendicular direction with loading,which appears to be a brittle break.And the compressive rupture samples ex...
Keywords:glass fiber bundles  foam plastics  quasi-static  tensile properties  compressive properties
