玻纤增强聚酰胺6／蒙脱土复合材料的制备及其力学性能研究

摘要

通过螺杆挤出法制备了玻璃纤维增强聚酰胺6／蒙脱土复合材料，利用电子万能试验机对复合材料的力学性能进行了测量，并对实验结果进行了分析。结果表明，随着玻璃纤维含量的增加，聚酰胺6／蒙脱土／玻璃纤维复合材料的拉伸强度和冲击强度相应地增大，且长度为12mm的玻璃纤维增强的复合材料比6mm玻璃纤维增强的复合材料高；当玻璃纤维含量为10％（质量分数，下同）时，12iTIIll玻璃纤维增强的复合材料的拉伸强度和冲击强度分别比聚酰胺6／蒙脱土复合材料提高了17．4％和84．1％。%Glass fibers reinforced polyamide 6/montmorillonite composites were prepared via screw extruding method. Their mechanical properties were measured by an electronic all-powerful tester. It was observed that the tensile and impact strengths of the composites increased with increasing content of glass fiber. At a same loading, the strengths based on 12 mm glass fiber were higher than those on 6 mm glass fiber. When the content of glass fibers was 10 % （12 ram）,the tensile strength and impact strength of the composites respectively improved 17. 4% and 84. 1 compared with those of the plain polyamide 6/montmorillonite composites.
