摘　　要：采用自行设计的蒸气爆破装置对棉秆皮进行预处理并对处理后纤维的外观形态等方面进行了研究;使用正交试验设计来研究蒸气爆破预处理的爆破压力、含水率、保压时间等参数以及纤维的含量对线型低密度聚乙烯(LDPE)棉/皮纤维复合材料力学性能的影响程度和显著性。结果表明:植物纤维的含量对复合材料的拉伸强度和弯曲强度性能影响呈高度显著,爆破压力对复合材料的拉伸强度和弯曲强度性能影响呈显著,含水率对拉伸强度有影响,但对弯曲强度影响不显著,而保压时间对两个试验指标的影响都不显著。Cotton bast was pretreated with self-designed steam-explosion equipment,the appearance and morphology was investigated.Orthogonal experimental design were used to analyze the effects of steam explosion parameter such as pressure,moisture content,pressure holding time and the fiber content on the mechanical properties of composites.The results showed that the influence of fiber content was significant on both of tensile strength and bending strength of the composites.The steam explosion pressure influenced significantly on the tensile strength and bending strength of the composites.The moisture content had effect on tensile strength,while little effect on bending strength,and pressure holding time had little effect.
