Pressure Induced Variations in Mode II Behaviour of Uni-Directional Kenaf Reinforced Polymers
Main Article Content
Abstract
The purpose of this study is to determine how the gas cure pressure affects the Mode II interfacial brittle material behaviour of undergrad Kenaf fibre reinforced polymers. Ending-notch deformation experiments were used to examine the shifts in materials and geometric characteristics caused by the use of pressure on uni-directional kenaf samples. When the rigidity of several composite structures hardened at elevated pressure was investigated, it was discovered that both material and geometrical rigidity contributed to the strength of the laminate, although their contributions to overall rigidity varied. It is demonstrated that micro hardness levels, GIIC, are unchanged by rigidity because they are exclusively connected to the forces generated by the initiation and propagation of cracks. It is demonstrated that the depth of a character affects all attributes, particularly toughness. The relative shatter strength of composite material treated at 6 psi, 300 psi, and 700 psi varies. An optimal height of a core layer provides combined cohesive and adhesion barriers to fracture development, resulting in good fracture toughness.
