Multi-axial fiber reinforced pultrusion profile sandwich composite material bearing beam and preparation method thereof
The invention discloses a multi-axial fiber reinforced pultrusion profile sandwich composite material bearing beam and a preparation method. The multi-axial fiber reinforced pultrusion profile sandwich composite material bearing beam comprises a pultrusion pipe core material, a pultrusion pipe sealing material, a composite material web and a composite material panel, the pultrusion pipe core material has a rectangular section, and the outer surface of the pultrusion pipe core material is wound with winding fiber cloth and sealed by a pultrusion pipe sealing material; a plurality of pultrusionpipe core materials are arranged, the pultrusion pipe core materials are spliced and stacked to form a combined component in a beam shape, and the surface of the combined component formed by splicingand stacking the pultrusion pipe core materials is wrapped by wrapping fiber cloth. Resin is poured into the mold through a vacuum bag forming process, so that the panel, the web and the core materialare integrally formed at a time; the composite sandwich structure is adopted, the pultrusion profile is used as a core material, the composite is used as a surface layer and a web plate, and the advantages of the pultrusion profile and the composite sandwich structure are fully utilized, so that the compression resistance, the bending resistance, the shearing resistance and the stripping resistance of the component are remarkably improved, and the problems of low bearing capacity and interface stripping are solved.
本发明公开了一种多轴向纤维增强拉挤型材夹芯复合材料承重梁及制备方法，包括：拉挤管芯材、拉挤管封口材料、复合材料腹板和复合材料面板；拉挤管芯材为矩形截面，其外表面缠绕有缠绕纤维布，并且由拉挤管封口材料进行封口；拉挤管芯材设有多个，多个拉挤管芯材拼叠形成组合构件，呈梁的形状，多个拉挤管芯材拼叠形成的组合构件其表面外包有外包纤维布；本发明通过采用真空袋成型工艺将树脂灌入模具使得面板、腹板与芯材整体一次成型；本发明采用复合材料夹芯结构，以拉挤型材为芯材，以复合材料为面层及腹板，充分利用了拉挤型材和复合材料夹层结构两种的优点，使得构件抗压、抗弯、抗剪以及抗剥离能力显著提高解决了承载力低及界面剥离问题。
