针对天然纤维增强复合材料弹性力学性能的计算问题，提出了一种多尺度数值模型--投影纤维法（PF法）。它使用一个特定的有限元程序，这是与随机分布的短纤维。它考虑了复合材料部件的几何形状和力学性能。采用细观桁架有限元法模拟短纤维增强体。将相应的自由度投影到树脂基体的自由度上。增强大麻纤维聚丙烯复合材料的弹性性能的数值结果进行了比较，从实验中获得的。
Motivated by computing elastic properties of reinforced natural fibre composites, a multi-scale numerical model, named ‘the Projected Fibre approach (PF)’, is proposed. It uses a specific finite element procedure which is associated with a random distribution of short fibres. It takes into account of the geometry and the mechanical properties of composite’s components. A microscopic truss finite element is used to model the short fibre reinforcements. The corresponding degrees of freedom are projected on those of the resin matrix. Numerical results of the elastic properties of a reinforced hemp fibre polypropylene composite are compared to those obtained from the experiment.
