摘要:
通过分析现有竹篾层积材存在的密度高、力学各向异性等特点,进行针对性的复合材料结构设计以改善竹篾层积材料的冲击、弯曲等力学性能,以期在滑板等运动领域进行推广应用。本研究以7.0 g/cm3设计密度为目标,玻璃纤维布作为增强增韧材料,环氧树脂作为胶黏剂,分别制备3种面密度(35,100和160 g/m2)玻纤布增强的竹篾层积复合板材(简称G-LBSL),并对其弯曲强度和冲击刚度及界面剪切强度等性能开展研究。结果表明:玻纤布的复合使得传统竹篾层积材(7.5 g/cm3以上)在降低密度的基础上,抗冲击性能与弹性模量有明显的改善,并随着玻纤布面密度增加呈现正比例关系,其中弹性模量MOE、静曲强度MOR、冲击刚度分别最高增加26.3%,41.2%,55.0%; 进而在发挥竹篾单元柔韧性优良的基础上,还能够在高强度的体育运动中保持良好的弹性、韧性和稳定性能。
Abstract:
This study was aimed at improving the mechanical properties such as impact and bending strength of laminated bamboo sliver lumber(LBSL)by adding the fiberglass cloth as a reinforcement. The developed fiberglass reinforced LBSL could be better suited for sports equipment such as skateboards. The target design density of 0.7 g/cm3 was used for all composite samples produced in this study. Fiberglass cloth was used to reinforce the bamboo sliver and help to toughen LBSL. The epoxy resin was used as the matrix to construct the samples. Three separate area densities(35, 100, 160 g/m2)of the fiberglass cloth were used to prepare the composite samples. The composites were hot-pressed under the same temperature(110 ℃)and gauge pressure(3.0 MPa). Considering most of the physical-mechanical and interfacial properties, to assess the effects of variables on composites, the analytical methods including the scanning electron microscopy, and physical-mechanical measurements(flexural strength, flexural modulus, horizontal shear strength, tensile shear strength and shock stiffness)were conducted. The results of the analysis of the fiberglass reinforced laminated bamboo sliver lumber(G-LBSL)showed that the fiberglass cloth made the obvious improvements compared with the traditional bamboo slivers(with the density of 7.5 g/cm3 or higher)in the impact resistance and flexural strength on the basis of density reduction, and the surface density increased with the adding of fiberglass. Compared with the traditional LBSL, it was shown that the elastic modulus, static bending strength, and shock stiffness were increased by 26.3%, 41.2%, and 55.0%, respectively. However, due to the problem of the glued interface between the fiberglass layer and the bamboo layer, the increase in elastic modulus exhibited an inverse proportional relationship with the density of the fiberglass cloth. When the sheet was reinforced with fiberglass cloths having the areal densities of 35 g/m2 and 160 g/m2, respectively, the difference in elastic modulus was about 21%. Therefore, because of the excellent flexibility of the bamboo sliver units, the fiberglass reinforced LBSL maintained good elasticity, toughness and stability, and at the same time, improved the ability to resist impact damage in the vertical and horizontal directions. As a result, the fiberglass reinforcement made the LBSL to be suitable for the application as high-intensity sport materials.
