Effect of fiber orientation and fiber contents on the tensile strength in fiber-reinforced composites.
The study for strength calculation of one direction fiber-reinforced composites and the study measuring precisely fiber orientation distribution were presented. Need the systematic study for the data base that can predict mechanical properties of composite material and fiber orientation distribution by the fiber content was not constructed. Therefore, this study was investigated what affect the fiber content and fiber orientation distribution have on the strength of composites. Fiber-reinforced thermoplastic composites by changing fiber orientation distribution and the fiber content were made. Tensile strength ratio of 0 degrees direction of fiber-reinforced composites increased being proportional the fiber content and fiber orientation function as change from isotropy (J = 0) to anisotropy (J = 1). But, tensile strength ratio of 90 degrees direction by separation of fiber filament decreased when tensile load is imposed for width direction of reinforcement fiber length direction.
