Abstract
The mechanical properties such as the elastic modulus and the breaking stress of the glass fiber reinforced Nylon 6 (FRTP) are studied by tensile test and photoelastic experiment.
The elastic moduli of the composite materials below 15% fiber content lied between the theoretical curve of unidirectionally arranged fiber model and that of another model of the glass fibers mat attached to the matrix. The breaking stress was almost constant and the breaking strain decreased with increasing the fiber content to 5 volume %, but both increased over 5%. It was found by photoelastic experiment that the mechanism of reinforcement was influenced by the fiber length, the number of fibers and the fiber arrangement in the matrix.
