Modelling of Void Reduction in Two Dimensional Cantala Fiber/Recycled HDPE Composites Using FEM

摘要

The presence of void effect on the decrease in the mechanical properties of composites so the controlling of voids needs to be done. The aim of this research is to simulate the controlling of voids in composites by setting the displacement of the upper plate of hot press. The simulation was described in two-dimensional design by ANSYS software. The comparison of fiber, matrix, and void were set of 45%, 45%, and 10% respectively, while the geometry of the fiber was the diameter of 0.12 mm and length of 2.5 mm. Displacements of upper plate were varied 0.1 mm, 0.1075 mm, 0.115 mm, 0.1225 and 0.13 mm. The simulation results showed that increasing the displacement upper plate would be followed by decreasing of void content. The displacement of the top plate of 0.13 mm caused voids in the composite to be minimum, a tensile stress on the fibers of 2393.13 kPa and a tensile stress on the matrix of 285.43 kPa.
