摘要
Sawdust (20wt%) reinforced polypropylene composites were prepared with 22.4 wt% maleated polypropylene coated fibers. Tensile tests were performed at 400, 5 and 0.1 mm/min for composites and matrix. Scanning electron microscopy of these fracture surfaces together with the shape of the stress strain curves characterized ductile, brittle and ductile-to-brittle transition fracture modes. Processing conditions as well as the development of interfacial fiber/matrix adhesion are also discussed. (C) 2000 Elsevier Science Ltd. All rights reserved.
