中文摘要：

我们使用了造纸厂污泥(下午) 代替过去常增强高密度聚乙烯(HDPE ) 的木头纤维(WF ) 的部分。产生 composites 受到捱过的氙弧。合成充满了有限下午(不到 10 ?%) 没有下午的类似于那些的有的机械性质和老化抵抗。没有下午，包含更多的下午的 composites 比那些更乐意地褪色并且裂开。基于羰基索引， crystallinity，和木头索引，下午看起来在捱过期间加速 composites 的降级。补充说到 WFHDPE composites 的下午减少了捱过的抵抗，并且如果 PMS 满足，这减小不是重要的没超过 20 ? 木头纤维的 % 。因此，下午能在层次在木头塑料 composites 被用作加强不到 20 ? 木头纤维内容的 % 。

英文摘要：

We used paper mill sludge（PMS） to substitute for part of the wood fibers（WF） used to reinforce high density polyethylene（HDPE）.The resulting composites were subjected to xenon-arc weathering.The composite filled with limited PMS（under 10 %） had mechanical properties and aging resistance similar to those without PMS.The composites containing more PMS faded and cracked more readily than those without PMS.Based on the carbonyl index,crystallinity,and wood index,PMS appeared to accelerate the degradation of composites during weathering.Adding PMS to WF–HDPE composites reduced the weathering resistance,and this reduction was not significant if the PMS content did not exceed 20 % of the wood fibers.Therefore,PMS could be used as a reinforcement in wood-plastic composites at levels less than20 % of the wood fiber content.
