The invention relates to the technical field of preparation of automobile door interior decorative plates, in particular to a composite fibrofelt for an automobile door interior decorative plate, a composite plate and a preparation method and application of the composite fibrofelt and the composite plate. The raw materials of the composite fiber felt comprise glass fibers and polypropylene fibers; the mass ratio of the glass fibers to the polypropylene fibers is (4-6): (4-6) The thermoplastic fibers and the inorganic matter fibers are needled and consolidated according to a certain proportion to prepare the composite fiber felt, so that the problem of easy deformation caused by high thermoplastic components is avoided, the cohesive force between the two fibers in the composite fiber felt is maintained, the stress transfer continuity of resin in the material is effectively improved, and the service life of the material is prolonged. The breaking strength and the elongation at break of the thermoplastic light composite board are improved.
本发明涉及汽车门内装饰板制备技术领域,特别是涉及一种用于汽车门内装饰板的复合纤维毡、复合板材及其制备方法和应用。复合纤维毡的原料包括玻璃纤维和聚丙烯纤维;玻璃纤维和聚丙烯纤维的质量比为4~6:4~6。本发明将通过热塑性纤维和无机物纤维按一定比例针刺固结制成复合纤维毡,避免了热塑性组分偏高而造成易形变的问题,保持了复合纤维毡中两种纤维间的抱合力,从而有效提高了材料内部树脂的应力传递连续性,提高了热塑性轻质复合板材的断裂强度及断裂伸长率。
