A biomaterial composite is made of a polymer matrix with aligned ceramic fibre reinforcement. The composite is deformed elastically under an applied stress of Oapplied = 200 MPa along the longitudinal direction (i.e. parallel to the fibres). The elastic modulus of the fibre, Ef, is 200 GPa and that of the matrix, Em, is 5 GPa. The volume fraction of the fibre is Vf = 20%. What is the strain experienced by the composite? 0.87% 1.10% 0.23% 0.45% A biomaterial composite is made of a polymer matrix with aligned ceramic fibre reinforcement.
