Abstract

Weight is one of the important aspects in the aerospace engineering because the increase of weight will make the needed of lift force also increase. In order to reduce weight of air spoiler on the airplane, the method of manufacturing material is the crucial factor to consider. The goal of this study is to fabricate composite specimen for hinge spoiler A320 airplane, by using Resin Transfer Molding technique. The composite material is chosen because of its characteristics such as light in weight and resist to corrosion. Initially, the hinge of the spoiler was made of metal, which have their own advantages and disadvantages. The research starts by fabricating the specimen by using Resin Transfer Molding (RTM). RTM is chosen because of low of volatiles released to the atmosphere, lower tooling cost compare to other competitive processes and has a good quality of product in term of surface finish and accuracy of the dimension. The process fabrication starts with lie the dry carbon in the mold and clamp the mold before inject the resin in the mold. Flow of the resin in the mold is by gravity pressure, to avoid formation of bubbles or porosity on specimen. Injected mold will be left to rest in the cooling process. Then the specimen will undergo testing process to obtained mechanical properties of material. Two types of specimens were designed with one and two plies of dry carbon respectively. The result of testing will be compared to the Hand Lay Up method. The result shows that the strength of the two plies of dry carbon has higher strength compared to one plies of dry carbon. The strength of the material is similar while using RTM method or Hand Lay Up method.
