Abstract

The purpose of this research is to develop new material of building partition wall and to determine the material properties of the new material. The new material is consist of coconut fiber as the reinforcement and mixture of epoxy resin and cornstarch as the binder. The mass scale use of synthetic fibers and synthetic binders in industry have a negative impact towards environment. Moreover, it also can impact human health and animal health. The use of natural binder and natural fiber can reduce the dependency on the synthetic binder and synthetic fiber as well as reduce the negative impact towards the environment, humans and animals health. Coconut fibers are extracted from the outer shell of a coconut. Coconut trees or its scientific name, Cocos nucifera are commonly found planted non-commercially in Malaysia especially in rural areas. The epoxy resin is a thermosetting matrix or resin that have more than one of epoxide groups that consist in the molecule. Epoxy resin is widely used as a versatile adhesive that can be used with several materials including wood, fabric, glass or metal. Cornstarch is a biodegradable polymers that can be used in many application including cooking ingredients, used as thickening agent and adhesive purpose. The specimen samples are prepared by mixing the coconut fiber and the mixture of epoxy resin and cornstarch by using hand lay-up technique. The prepared specimen samples are tested for tensile test and flexural test using Instron 5969 Series Universal Testing Machine (UTM). All the test was adhered to ASTM D3039 and ASTM D790 respectively. Based on the obtained results, it was found out that the specimen samples of 20% coconut fiber + 80% epoxy resin and cornstarch showed the best result for the tensile test and flexural test. By using the 20% coconut fiber + 80 epoxy resin and cornstarch composition, the building partition wall was fabricated. Lastly, all the objectives of this research have been met where the new material of building partition wall has been developed and the material properties of the new material have been determined
