Calculate the modulus of elasticity of fiberglass under isostrain condition if the fiberglass consists of 70% E-glass fibers and 30% epoxy by volume. Also, cal- culate the percentage of load carried by the glass fibers. The moduli of elasticity of the glass fibers and the epoxy are 70.5 and 6.9 GPa, respectively. If a longitu- dinal stress of 60 MPa is applied on the composite with a cross-sectional area of 300 mm², what is the load carried by each of the fiber and the matrix phases? What is the strain sustained by each of the fiber and the matrix phases?
