The Strength of Flax/Epoxy and Glass/Epoxy Composites: Fiber s Orientations

In this research, the tensile behavior of epoxy matrix composites is investigated in different orientations. The composites are reinforced with bio and synthetic fibers. Four different types of composites, with five layers, are constructed by epoxy- E glass and epoxy- flax composites in two different arrangements, i.e. (0 0 0 0 0) and (45 30 0 30 45). All composites strengthened with woven fibers are made by Vacuum Infusion Process (VIP) method. In addition to the experimental tensile results, the mechanical behavior of these composites is predicted with a Matlab code. It is found that there is an appropriate correlation between the experimental and numerical procedures. Alongside, the role of the fiber s orientation on the mechanical properties of bio-composite and epoxy-E glass specimens are compared. The compassion shows that the tensile behavior of glass/epoxy composite is more sensitive to fibers’ orientation than that of flax/epoxy composites.
