Mechanical Behavior of Compositions of Glass-fiber Reinforced Plastic Mortar Pipes Based on Their Functioning

The experimental investigation on the mechanical parameters compositions of glass-fiber reinforced plastic mortar (GRPM) pipe is the basis of simulating and analyzing the mechanical characteristics of the complete structure of GRPM pipe. Due to the anisotropic material properties of GRPM pipe, the compressive property test is carried out, and the results show that the circumferential compressive strength(CCS) is 49.93Mpa, the axial compressive strength(ACS) is 40.79Mpa, the circumferential elastic modulus(CEM) is 4.84Gpa, and the axial elastic modulus(AEM) is 4.04Gpa. The difference between the CCS and ACS and EM is about 20%, as well as the CCS and EM are greater than the ACS and modulus of elasticity. Conclusions drawn from the tests provide an important basis for checking whether the materials meet the design requirements.
