PE/木粉复合材料的性能研究

Study on Properties of PE/Wood Powder Composite

考察了木粉含量对聚乙烯（PE）／木粉复合材料性能的影响，包括密度、弹性模量、弯曲强度、最大破坏载荷与长度膨胀率。结果表明：当木粉含量从55份增加到65份时，PE／木粉复合材料的密度、弹性模量、弯曲强度、最大破坏载荷都有不同程度的提高；受冷时（-30℃），长度膨胀率增大，受热时（60℃），长度膨胀率减小。

This paper tested the influence of wood flour content on the PE/wood flour composites, including density, elastic modulus, bending strength, the maximum failure load and the length of the expansion rate. The results showed that： when the wood flour content from 55 to 65 phr, the density, elastic modulus, bending strength, the maximum failure load and the length of the expansion rate of PE/wood flour cotnposites increased. When cooled （ - 30 ℃） , the length of the expansion rate increased, When heated （ ＋60 ℃） , the length of the expansion rate decreased.
