abstract

In this study, the short glass fiber reinforced polyoxymethylene composites were fabricated by direct fiber feeding injection molding (DFFIM). The processing parameters such as number of fiber, matrix feeding speed and screw rotational speed are study the effect on fiber content, fiber length and mechanical properties. Fiber orientation and fiber distribution are observed by scanning electron microscope. The maximum and minimum fiber content are 34.1 and 11.5 wt.%, respectively. The increasing of number of fiber and screw rotational speed and the decreasing of matrix feeding speed lead to the increasing of fiber content. Tensile modulus increase when fiber content increase. However, tensile strength do not increase when fiber content is over 23.3 wt.% due to poor orientation and distribution of glass fiber.
