Study of material homogeneity in the long fiber thermoset injection molding process by image texture analysis

To quantify the homogeneity of fiber dispersion in short fiber-reinforced polymer composites, a method for image texture analysis 3-dimensional X-ray micro computed tomography (µCT) images is presented this work. The adaption to specific requirements composite material accomplished using statistical region merging approach. Subsequently, applied evaluating specimens from an intermediate step long thermoset injection molding process as well molded parts. This new enables manufacturing parts with flexible combination and glass fibers. By newly developed screw element based on Maddock mixing design, improved.
