A composite is made up of C-fiber/Polyester. The weight fraction of C-fiber is 55% in final composite. If the modulus fir C-fiber and polyester resin is respectively 400 GN/m ² and 3.45 GPa, find out the modulus of C-fiber/Polyester laminate. Also calculate the fraction of externally applied load taken by the C-fiber. Also find out the longitudinal tensile strength (σ _LTU ) for the laminate. The tensile stress at fiber breaking elongation is 2.1 GPa for C-fiber and 0.045 GPa for Polyester. (ρ _C-fiber = 1800 Kg/m ³ and ρ _Polyester = 1100 Kg/m ³ )
