The invention relates to polymeric composites. A composition comprising 65 to 90 weight percent kraft chemical wood pulp fibers and a thermoplastic polymer and a method of making the composition. In one embodiment, amounts of about 5-10 %, and in another 0.2-5 % of the coupling agent is incorporated into composite formulations and melt processable compositions. Fillers and fibers other than chemical wood pulp fibers may be added to the fiber/polymer blend to impart desirable physical characteristics or to reduce the amount of polymer needed for a given application. 本发明涉及种聚合物复合材料。具体地，本发明涉及种包含65至90重量％的硫酸盐化学木浆纤维和热塑性聚合物的组合物，以及所述组合物的制造方法。在种实施方式中，将量为约5-10％以及在另种实施方式中将量为约0.2-5％的偶联剂掺入到复合材料配方和可熔融加工的组合物中。可以向纤维/聚合物掺混物添加填充剂和化学木浆纤维之外的纤维，以赋予所需物理特征或降低用于给定应用所需的聚合物的量。
