摘要/Abstract

摘要： 以先进拉挤(Advanced Pultrusion,简称ADP)制备复合材料豆荚杆为背景,分析现有工艺的不足,提出了预处理工艺,以减轻制件表面纤维畸变和两侧厚度不足等缺陷。着重研究了预处理温度和时间对制件的作用机理,并以轴向拉伸性能和层间拉伸强度表征预处理工艺对试样的影响。试验结果表明,①100℃保温50min、105℃保温40min、110℃保温25min三组参数符合预处理工艺要求;②经试验验证,相对直接热压成型,上述预处理工艺参数下制得的试样力学性能没有明显的降低,预处理温度越低,相应的预处理条件下制得的试样力学性能越高。

Abstract: To decrease the defects such as fiber distortion and insufficient thickness on both sides of the half lenticular tube, pretreatment process was proposed by analyzing the shortcoming of the existed advanced pultrusion process. The temperature and time of pretreatment were stydied with an oven and a hot-pressing device, the axial tensile property and interlayer tensile property were carried out to analyze the effects on the samples. The result showed suitable parameters for pretreatment process were 100℃ for 50min, 105℃ for 40min, 110℃ for 25min; the mechanical properties of the product didn't decrease with pretreatment process; the lower the pretreat temperature was, the better mechanical property the sample could reach.

Key words: half lenticular tube, advanced pultrusion, pretreatment, fiber distortion, thickness
