| 摘 要： | 玻璃纤维毡种类及其结构对熔体浸渍、片材孔隙率、力学性能及预热膨化有着很大影响。实验研究表明,PP熔体浸渍连续针刺玻纤毡的渗透率较大,所得片材孔隙率最低,且具有均衡的力学性能。说明连续玻璃纤维原丝针刺毡的立体弹性结构有利于熔体的浸渍和气泡的排除,是较理想的GMT增强材料。

| Abstract: | The types of glass fiber mats and their configuration strongly affect the melt impregnation, void content, mechanical properties of GMT sheets, and the loft ratio of sheets during the preheating process. The configuration of the snitched continuous glass fiber mat is elastic structure, and that is good for melt impregnation and elimination of the air in the sheets. The experimental results show that the snitched continuous glass fiber mat is an ideal reinforcement for GMT sheets, and it has higher permeability over the chopped and complex glass fiber mat. The sheets reinforced by the snitched continuous glass fiber mat have lower void content, and their mechanical properties are balanced. |
