E-Glass/phenolic matrix/APP laminate as a potential candidate for battery casing of e-vehicle - experimental investigations

The prime purpose of the current research is to investigate the influence of Intumescent flame retardant (IFR)-Ammonium polyphosphate (APP) on the mechanical properties of Phenolic resin/E-Glass hybrid configurations and suitability of hybrid configuration for battery casing in E-vehicle. Varying weight fractions viz. 2, 4, 6, 8, 10 wt% of APP were used to fabricate -Phenolic resin/E-Glass/APP polymer composites. Tensile, flexural, low velocity impact, and quasi static indentation tests were conducted and analyzed. Among the developed hybrid configurations 6 wt% APP filled laminate shows the better tensile and flexural properties than other configurations. It is understood from low velocity Izod impact test, falling weight impact test and quasi static indentation tests that APP filled hybrid configurations have more energy absorption. 6 wt% APP filled laminate has high deformation in elastic phase and low deformation in plastic phase. Morphology and fracture mechanism of polymer laminates are also presented and discussed. It is concluded from the investigations that E-Glass/Phenolic matrix/APP laminate is found as a potential candidate for battery casings of E-vehicle. (paper)
