Unformatted text preview: properties: Ef = 70 GPa, Em = 6 GPa; Ecomposite = 9 GPa for an isostress condition . a. Calculate Ecomposite for an isostrain condition. (Ans. Ecl = 29 GPa) b. In this case, which of the two components, matrix or fibre, is more likely to be a ceramic material? Explain you answer. (Ans. Fibre) σ = F/A σ =E ε ε = Δ l/l Ecl = EmVm + EfVf 1/Ect= Vm/Em + Vf/Ef Ecd = KEmVm + EfVf Pcomposite = Pmatrix Vmatrix + Preinforcement Vreinforcement M. McDill AERO3700...
