Question

• An E-glass fiber (E_f = 1.0x10⁷ psi, Tensile strength S_ften = 5x10⁵ psi, r=2.6 gm/cm³) unidirectional fabric (600 gm/m²) has a volume fiber fraction of 0.4. The matrix is vinyl ester resin (E_m = 4x10⁵ psi, Tensile strength S_mten = 1.2x10⁴ psi, r = 1.15 gm/cm³).

1. What is the density of the laminate?
2. What is the Mass fiber fraction M_f?
3. What is the longitudinal modulus of elasticity of the laminate?
4. What is the tensile strength of the laminate?
5. What is the thickness of the laminate?
6. How much load can a 1 inch wide strip of the laminate support?
