Study On Static And Dynamic Mechanical Response Of Basalt Fiber Composite Laminates

Basalt fiber composite laminated plate with the advantages of its high strengthhas been in machinery manufacturing,shipbuilding,power energy industry,building materials industry and other fields.Analysis of mechanical static and dynamic load response of laminated composites is not only the main content of the viability of material structure,but also an important basis for the design of composite material struct ure,and it has become a hot research focus in the field of composite material.In this paper,the elastic modulus,deformation and damage law of laminated plates are studied by means of experiment,theoretical analysis and numerical simulation,The main con tents include:1.The material properties of basalt fiber reinforced composite laminates under static load are studied.The theoretical formula for predicting the transverse,longitudinal and shear elastic modulus of basalt fiber reinforced composite laminates is derived,Compared with the experimental results,it is found that the absolute error between theoretical value and experimental value is less than 10%.2.The bearing capacity of basalt fiber reinforced composite laminated circular plate subjected to local uniform load is studied,based on cylindrical coordinates of orthotropic laminated circular plate balance equation,physical equation,geometric equation are solution by means of Fourier series,Then,the ultimate static load of laminated circular pl ate is obtained by introducing the physical equation.Compared with experimental results,it is found that the abso-lute error between theoretical value and experimental value is less than 15%.3.The damage and failure of basalt fiber reinforced composit e laminates are studied.The mechanical response of laminated plates under different impact energy is obtained by the test of laminated plates subjected to low velocity impact loading.The damage law is summarized under different low velocity impact load.
