Composite are structural materials made up of two or more materials such that each component remains separate on microscopic level within the finished material, but for which the composite properties are superior to those of the individual component materials alone. The term “hybrid composites” represents a composite having at least two different types of fibres reinforced in the single matrix, or blends of polymer mechanical properties. The purpose of this study was to fabricate a sago fibre composites and sago fibre reinforced with white sacks as car door panel. Ansys Software is used for structure testing for each of these specimens. The software will show the structure strengths either is it strong enough to be a good material or not. The purpose also is to reduce the use of plastic by using a hybrid polymer composite and also to utilize waste like sago fibre and white sacks to be made into something useful. In conclusion, this project will provide a good material to be a car door panel. Hence, the environment also will be better in the future.
