The Influence of Basalt Fiber Orientation on the Mechanical Property of Composite Board

Abstract:

The composite board was made of chopped basalt and polypropylene fibers. The manufacturing process included blending, carding, web formation, laminating and compression molding. The tension and bending properties were investigated experimentally. The load - displacement curve of the tensile test revealed that the elastic modulus and maximum vertical load in the longitudinal were far greater than these in the transverse direction; and tensile strengths were far apart in the longitudinal and transverse direction as well. In comparison with the tensile tests, the effect of basalt fiber orientation on the bending modulus and strength were relatively insignificant. In addition, from the micro fibril angle, we also verify that the orientation angle of basalt fiber is an important factor of influence to the mechanical property. In the similar study, the influence hadn’t been seen sufficiently, so this paper provides reference to the actual application of the composite board.
