Abstract

Fiber-reinforced polymeric (FRP) composites are being considered for structural members in construction as lighter, more durable alternatives to steel and concrete. Unlike steel and similar isotropic materials where mechanical properties are independent of the applied load directions composites are anisotropic materials by nature. Pultredud FRP structural members that are considered unidirectional members are subjected to premature failure due to discontinuity of fiber in the transverse and through the thickness of the members in a shape of delamination failure. Proposed box-section structural member by utilizing filament-winding process using· woven roving mats instead of roving strands to reorganize the fibers in produced member has presented in the study to overcome the premature failure associated with unidirectional structural members. Flexure and buckling tests were conducted on box-section. The stiffness and strength aspects studied including the mode of failure and the influence on strength of the manufacturing process by filament winding and woven roving mats. FRP sections produced using filament-winding process have exhibited a significant enhancement in the mechanical properties. Good performance in resisting premature failure due to delamination of the proposed technique was obtained and provided a basis for developing new sections or similar sections with modified properties to avoid premature failure of FRP structural.
