摘　　要：通过对木粉-高密度聚乙烯基木塑窗型材的胶接和焊接2种连接方式的角部连接技术研究,结果表明,使用环氧树脂胶接时,随着木粉含量的增加木塑窗角部受压弯曲应力呈增大趋势;对木塑型材进行等离子体处理可使角部受压弯曲应力提高97.3%。采用焊接方式连接时,随着木粉含量的增加,角部受压弯曲应力大幅度降低;向型材保温腔中填充高密度聚乙烯,可增大焊接面积,使最大受压弯曲应力提高为22.40 MPa。In this article, two corner connection methods, cementing and weld of wood fiber-high density poly- ethylene （WF/HDPE） to composite window were investigated. The results showed that, when bonded by epoxy resin, the corner bending stress of WF/HDPE profile was improved with increasing wood component in profile. When the cross section of WF/HDPE profile was treated with plasma, corner bending stress was increased by 97.3%. When WF/HDPE profile was connected by hot welding method, corner bending stress decreased signifi- cantly as wood component increased. Enlarge the welding area could increase the corner bending stress. Filling the thermal insulation cavity of the window profile with HDPE could improve the corner bending stress of 22.40 MPa.
