Abstract
The stress-strain relations of hybrid reinforced plastics are experimentally determined by subjecting filament wound tubes with various material constitutions to axial load, torsion and internal pressure. The testing materials are hybrid reinforced plastics of two combination from glass fiber, carbon fiber, and aramid fiber reinforced plastics. The stress-strain curves of constituent reinforced plastics are formulated by using the third order equations of stress components. The stress-strain relations of hybrid reinforced plastics are derived from the relations of constituent reinforced plastics on the assumption of perfect bonding between two layers of the constituent reinforced plastics. The stress-strain curves calculated by obtained relations represent the characteristic behavior of experimental curves under combined stress states as well as uniaxial stress state.
