Q.1: A composite Materials has a longitudinal modulus of elasticity of 18.2 GPa. Containing unidirectional glass fiber in an epoxy matrix. Determine
a) Volume Fraction of glass fiber and epoxy matrix
b) The density of the composite
c) The ratio of the load carried by the fiber to that carried by
the matrix.
Note
The density of epoxy =1.3 gm/cm3
The density of glass =2.2 gm/cm3 E of epoxy = 2.75 GPa Eofglass =380GPa
