The Impact

The present study concentrates on development of conceptual proof for sisal reinforced polymer matrix composite for structural applications subjected to low velocity impact using a finite element (FE) approach. The proposed sisal-epoxy composite of various thicknesses of 3.2 mm, 4 mm and 4.8 mm is subjected to different impact velocities of 1 m/s, 2 m/s and 3 m/s ranging in the low velocity impact regime to study the energy absorbed and damage mitigation behaviour of the proposed composite. The consequence of velocity of impact and thickness of laminate on the sisal epoxy composite’s impact behaviour is assessed statistically using Taguchi’s experimental design. Outcome of the present study discloses that the energy absorption increases with increased impact velocity and laminate thickness. However, the statistical study shows that impact velocity is predominant factor affecting the impact response of sisal epoxy composite laminate compared to laminate thickness. The role of matrix and fiber in damage initiation is studied using Hashin criteria and it is found that matrix failure is predominant over the fiber failure.

The Impact

This paper demonstrates both low velocity impact and mechanical test results of glass/epoxy composites at room and high temperatures. Square specimens of glass/epoxy composite laminates with lay-ups [0/0/90]s, [90/0/0]s, [0/90/45]s were subjected to low velocity impact energy range of 4 J to 22 J using an impact test machine at temperatures of 20°C, 50°C and 90°C. Load-deflection and energy profile diagrams were plotted for each stacking sequence and temperature. After impact, a high-intensity light was used to measure the projected delamination areas in the impacted glass/epoxy composite laminates. In order to investigate effects of temperature on mechanical properties and impact resistance, mechanical tests were also performed using unidirectional glass/epoxy composite plates composed of eight plies produced according to ASTM Standards. In addition, to understand the contribution of thermal residual stresses occurring during and after manufacturing of composite laminates on impact-induced delamination, SX and SY stresses in the composite laminates at 20, 50 and 90°C were determined by using ANSYS software. It can be concluded from this study that temperature has significant effects on the impact behaviour and mechanical properties of glass fibre-reinforced epoxy composite laminates. Besides, an increase in temperature decreases both the delamination area and the contribution of thermal residual stresses on delamination under the same impact loading.
