摘　　要：树脂与纤维复合可显著增强材料的性能,广泛用于家居建材领域。本研究将竹纤维布与丙烯酸树脂复合,以马来酸酐(MA)改性竹粉和TiO_(2)为填料,改善其界面相容性,制备了树脂增强竹纤维布复合片材,并对其微观结构和性能进行探究。结果表明:MA改性竹粉制备的片材其微观表面更光滑,填料在竹纤维布内部的分布更加均匀致密。MA改性后,竹粉表面的羟基数量减少,有利于充分浸入竹纤维布内部。同时,改性后样品的疏水性能有所提升,其抗拉强度和应变最高可分别提升80.73%和48.36%。研究结果拓展了竹纤维复合材料的应用范围。Resin-fiber composites could significantly enhance the properties of materials,which can be widely used in the field of home building materials.In this study,bamboo fiber fabric was combined with acrylic resin,then bamboo powder modified with maleic anhydride(MA)and TiO_(2) were employed as fillers to improve the compatibility of the interface,resulting in the fabrication of resin-reinforced bamboo fiber fabric composite sheets.The microstructure and properties of the prepared sheets were evaluated.The results indicated that the material prepared with MA-modified bamboo powder exhibited a smoother and denser microsurface,with fillers distributing more uniformly and compactly within the bamboo fiber fabric.The number of hydroxyl groups on the surface of the bamboo powder reduced after MA modification,facilitating the thorough impregnation of the slurry into the interior of the bamboo fiber fabric.The addition of MA-modified bamboo powder enhanced the hydrophobicity of the samples.The tensile strength and strain can be increased by up to 80.73%and 48.36%,respectively.The research results broadened the application scenario of bamboo fiber composite materials.
