Abstract

Current production units of the Airbus A320 family are using metal hinge for their spoiler centre hinge which is both heavy and susceptible to corrosion over time. Composite materials are lighter in weight and less susceptible to environmental factors. To address this problem, a new composite hinge design will be developed using composite materials. The objective of this project is to determine tensile properties of dry carbon reinforced epoxy composite using hand layup method which will be compared to specimen from RTM method. The advantage of using hand layup method is that the more complex shape can be produced relatively easier when compared to other production method such as resin transfer moulding (RTM). The properties of dry carbon reinforced epoxy composite will be tested using tensile test methods according to ASTM D3039 standards. Due to the complex nature of the centre hinge design, hand layup is a very promising method of production. It can be said that based on the tensile test conducted, the higher the number of woven carbon fibre used to higher the strength of the composite. However, the RTM was able to fabricate specimen with a better surface finishing and shows better tensile properties when compared to hand layup and thus it more desirable method to produce the composite hinge.
