Qu. 5 Composite materials are becoming more widely used in aircraft industry due to their high strength, low weight and excellent corrosion resistant properties. As an engineer who is given task to design the I beam section of an aircraft (see Figure 7) please, answer the following questions given the material properties in Table 3. (a) Determine the Moduli of Elasticity of Carbon/Epoxy, Aramid/Epoxy, and Boron /Epoxy composites in the longitudinal direction, given that the composites consist of 25 vol% epoxy and 75 vol% fiber. (b) What are the specific moduli of each of these composites? (c) What are the specific strengths (i.e. specific UTS) of each of these composites? (d) What is the final cost of each of these composites?
