摘要
研发了纤维增强复合材料参数测试仪。首先,基于复合梁试件的激振平台、激光扫描装置、信号发生及数据采集器等功能部件,完成了纤维增强复合材料参数测试仪硬件结构的搭建;然后,对基于Lab VIEW编写的软件各个模块的功能和测控优势进行了详细说明;最后,辨识获得了两个TC500碳纤维/树脂基复合梁试件在纤维纵向、横向、剪切方向的弹性模量、损耗因子和泊松比,并与厂家所给的材料参数进行了对比,偏差在2. 75%～11. 82%,验证了该测试仪和软件程序算法的有效性。相比于市面上已有的商业化仪器,研发的测试仪采用了激光无损扫描技术,且性价比更高,还可有效获取各向异性复合材料在剪切方向的损耗因子。
A material tester of fiber-reinforced composite is developed.Firstly,the excitation platform,laser scanning device,signal generator and data acquisition device are utilized to establish its hardware structure.Then,the functions as well as control and measurement advantages of each software module based on LabVIEW are described in detail.Finally,the elastic moduli,loss factors and Poisson's ratios of the two TC500 carbon fiber/resin composite beam specimens in the longitudinal,transverse and shear directions are identified,which are also compared with the material results provided by the manufacturer.The results show that their deviations are in the range of 2.75%~11.82%,which is within an acceptable level.Therefore,the effectiveness of the developed composite material tester and its software algorithm has been verified.Compared with the commercial instruments available on the market,the tester developed in this paper adopts laser non-destructive scanning technology,has higher cost performance,and can effectively obtain the loss factors of the anisotropic composite in the shear direction.
