Determination of the Mechanical Properties of Oriented Short Fibre Reinforced Thermoplastics under Different Stress States

This paper presents several methods to examine fibre reinforced specimens at the three principle stress states and at different fibre orientations. The specimens for the different stress states were machined out of the same injection moulded high oriented test bar. The specimen preparation allows load directions in and perpendicular to the fibre orientation. From these experiments the influence of the fibre orientation on the material properties can be determined.
