wood composites interface

composites of polyvinyl chloride-wood fibers. iii - wiley online library

the performance of silanes as coupling agents in aspen fibers. (chemithermomechanical pulp and sawdust)-polyvinyl chloride composites, have been investigated. aside from the chemical structure of silanes, the disper- sion aids, e.g. solvent, initiator (different organic peroxides) and maleic anhydride. (which provides various chemical reactions as well as physical/chemical inter- actions at the interface), play important roles on the mechanical properties of the composites.【Get Price】

mechanical properties of wood flake–polyethylene composites. ii

8 jan 2002 abstract. this article discusses the methods of interface modification of composites based on raw wood flakes and high-density polyethylene (hdpe) and the effects of these modifications on composite properties. an hdpe matrix was modified by a reaction with maleic anhydride (ma) in a twin-screw extruder and then compounded with wood flakes to produce wood–polyethylene composites. wood flakes were modified by a reaction with a silane coupling agent in an 【Get Price】
