Manufacturing of composites is different from metals and requires special techniques. Therefore, this paper is dedicated to explaining in detail the manufacturing process for preparing the composite GFRP (glass fiber reinforced plastic) crash boxes. In this research paper, step by step procedure for manufacturing of the specimens is presented with details. The various steps involved in the manufacturing technique require design of moulds, estimation of curing time, techniques of curing and the methods of removal of the specimens from the moulds. Hand lay-up technique is used for making all the GFRP composite crash boxes in the present research paper. Manufacturing of mould for the specimen, precautions while dealing with glass fibers, hardening agents and resins. Wrapping techniques and curing time prediction, use of releasing agents for pull out of specimens are explained.
