The invention provides a composite protective cross beam for a commercial vehicle. The composite protective cross beam for the commercial vehicle is made of a composite material formed by thermosetting resin and a fiber reinforced material. Wherein the thermosetting resin comprises a bisphenol A type epoxy resin material, and the fiber reinforced material comprises a unidirectional continuous glass fiber layer and a triaxial glass fiber fabric layer. Compared with a protective cross beam made of metal, the protective cross beam made of the composite material formed by the thermosetting resin and the fiber reinforced material is lighter in mass, higher in strength, better in toughness and better in corrosion resistance and fatigue resistance. In addition, the invention further provides a forming method of the commercial vehicle composite protection cross beam.

    本发明提供了一种商用车复合防护横梁,所述商用车复合防护横梁由包括热固性树脂和纤维增强材料形成的复合材料制成;其中,所述热固性树脂包括双酚A型环氧树脂材料,所述纤维增强材料包括单向连续玻璃纤维层和三轴向玻璃纤维织物层。本发明采用上述热固性树脂和纤维增强材料形成的复合材料制成的防护横梁,与金属制成的防护横梁相比,质量更轻、强度更高、韧性更好、更加耐腐蚀和抗疲劳。此外,本发明还提供一种商用车复合防护横梁的成型方法。
