Experimental Study of the Mechanical Properties of the Composite Materials Hose
The tensile elastic modulus, bend elastic modulus and tensile strength of the composite materials hose were determined by uniaxial tension test and three point bending test. The specimen was first destroyed from the inner or outer layer rubber, and then the spiraled cords threads was pulled out and the specimen destroyed with irregular fracture shape. According to the test results, the flexible hose can be considered as linear elastic material because the deformation showed a linear relationship with the external load in uniaxial tension test and three point bending test. The bend elastic modulus EB is much smaller than the tensile elastic modulus ET. The calculation results used EB show a good consistency with the test result and the EB should be selected as design parameters and the design system would be more secure.
