分别采用小麦秸秆、玉米秸秆纤维对聚己内酯进行改性,利用热压工艺得到了秸秆纤维/PCL复合材料;分别研究了小麦秸秆、玉米秸秆纤维的添加量对复合材料力学性能、降解性能的影响。研究结果表明:2种复合材料的断裂伸长率、拉伸强度呈现先增大后减小的趋势,通过比较2种复合材料的力学性能及降解性能,玉米秸秆纤维/PCL复合材料的性能相对较优。
The polycaprolactone was modified by wheat straw and corn stalk fiber, respectively. The straw fiber / PCL composite material was obtained by hot pressing process. The effects of the addition amount of wheat straw and corn stalk fiber on the mechanical properties, Impact. The results show that the elongation at break and the tensile strength of the two composites first increase and then decrease. By comparing the mechanical properties and degradation properties of the two composites, the properties of corn stalk fiber / PCL composites are relatively Better.
