Study of Elastic Behavior of Polylactic Acid with Yanchama Fibers Composite Simulated as Elastic Orthotropic Material

ABSTRACT

A new biocomposite material based on polylactic acid (PLA) with meshes of Yanchama fibers is introduced. This bio-based composite was fabricated by compression molding and film-staking process. This new biocomposite material was tested by tensile tests in different directions and was numerically simulated. The composite was simulated as an elastic orthotropic material. The nine constants of elastic orthotropic behavior are calculated from modules of Young measured experimentally. The experiment results and simulations are the same. The results show that the mechanical behavior of the PLA-Yanchama composite under different load solicitudes can be predicted if it is simulated as an orthotropic elastic material.

抽象

介绍了一种以聚乳酸(PLA)为基料,以盐沼纤维为网孔的新型生物复合材料. 该生物基复合材料是通过模压成型和涂膜工艺制备的. 对这种新型生物复合材料进行了不同方向的拉伸试验,并进行了数值模拟. 将复合材料模拟为弹性正交各向异性材料。根据实验测得的杨氏模量,计算了正交各向异性弹性行为的9个常数. 实验结果与仿真结果一致. 结果表明,将复合材料模拟为正交异性弹性材料,可以预测其在不同载荷下的力学行为.
