摘要：

Image analysis of C/PPS samples was done to detect the orientation of randomly oriented pellets on the surface. Binary image was discretized on facets with rotating abscissa with length of N pixels. The frequency of detected peaks depending on the orientation angle was analyzed and material isotropy was confirmed. Mechanical characteristics were calculated with modified lamination theory for randomly reinforced composites. FE simulation of the tensile test was verified with tests based on ASTM D3039. Isotropy which was confirmed from image processing analysis has not been fully confirmed from the verifying tensile tests due to great dispersion in measured values. (C) 2016 Elsevier Ltd.
