We examined the effects of process conditions on Young's modulus and tensile strength of extruded short-fiber reinforced thermoplastics. With increasing extrusion ratio and decreasing extrusion temperature, the fiber alignment increases, the mean fib

The in-plane angle determined using an optical reflection microscope with an image analyzer is ambiguous, because the same elliptical image would be obtained for a fiber. A method of determining the three-dimensional (3D) fiber orientation distributi
