摘要: Natural fiber composites consisted of homopolymer polypropylene, polyoxymethylene, maleic anhydride–grafted polypropylene, and coconut fibers were produced by co-rotating twin screw extruder. The mechanical and thermomechanical properties of the polypropylene composites were determined by uniaxial tensile, impact, and flexural tests; thermogravimetric analysis; and differential scanning calorimetry. The dispersion of the coconut fibers in the polypropylene was studied by optical microscopy and scanning …
