Investigation of Material and Manufacturing Process to Develop High Pedestrian Safety Composite Bonnet

Abstract

Cost reduction, light weighting, quality and safety are the basis for all design and development of automobile component manufacturing. Low cost with high quality components can be produced by proper material selection, material cost, production volume, manufacturing process. This paper investigates the existing metallic bonnet with a new low cost and light weight composite bonnet. Fibers such as glass and jute along with matrixes of polyester and epoxy resin are selected for part fabrication. Using reverse engineering process design is extracted from original metallic bonnet and is redesigned for FRP application. Hand lay-up and VARTM manufacturing process are compared to fabricate FRP bonnet. Important factors that involve in bonnet under real time damages are impact of child head-form during accident is analyzed as per Euro-NCAP standard. From the result VARTM based glass/ polyester composite is found to be a better candidate for fabrication. Keywords: Predestrain safety, Reverse enginneering, hand layup, VARTM, Analysis.

Electrical Power Generation Using Speed Breaker

“…The blowing of wind, the formation of clouds and the flow of water are some examples that bear witness to this fact. The extensive use of energy has resulted in an energy crisis and there is a need to develop optimal usage patterns that not only ease the crisis but also protect the environment [3]. The idea is basic physics, replacing the usual bitumen and stone chip rumble strip with five meter long metal plates welded to the speed-breaker.…”
