Polypropylene reinforced with glass fiber (28 percent by weight) was injection molded under different processing conditions. The influence of injection‐molding parameters such as pressure, injection speed, and injection temperature on the morphology and mechanical properties was studied using standard techniques, viz. polarizing microscope, scanning electron microscope, and Instron Universal testing machine. The observed mechanical properties were explained in terms of skin‐core‐morphology, transcrystallinity, fiber orientation and void volume. This study attempts to correlate processing conditions with morphology and mechanical properties. Such a study would help in optimizing processing conditions to give composites with desired properties.
