Replacing stitching and weaving in natural fiber reinforcement manufacturing, part 2: mechanical behavior of flax fiber composite laminates

ABSTRACT

Replacing weaving and stitching used in textile-based reinforcements by using short fibers as a binder was discussed based on the tensile and compressive properties of [0], [± 45], and [0/90] laminates. A slight decrease in the longitudinal properties of the [0] composites was accompanied by a significant reduction of the properties of variability. In the case of [± 45] laminates, the presence of the short flax fiber shows a positive effect on the tensile, shear, and compressive properties. The mechanical properties of [0/90] laminates have shown a limited effect of the short fibers, with a slight decrease of both modulus and strength.

摘要

以短纤维为粘结剂，在短纤维为粘接剂的基础上，以拉伸强度和压缩性能代替[1]，（±45）和（0/90）层合板，讨论了在织物增强材料中取代织造和缝合的方法。（0）复合材料的纵向性能略有下降伴随着性能变异性的显著降低。在（±45）层压板的情况下，短亚麻纤维的存在对拉伸、剪切和压缩性能都有积极的影响。[0/90]层合板的力学性能显示出短纤维的有限作用，模量和强度都略有下降。
