Detection of stacking orientation error of CFRP composite laminates using ultrasound waves
Abstract:A jig was developed for generating a shear wave. A pyramid with an isosceles triangle with two 45° was made of aluminum to generate shear waves using two longitudinal transducers based on ultrasonic-polarized mechanism. Also, the signal splitter was connected to the pulser jack on the pulser/receiver and to the longitudinal transducers. Therefore, an experimental way was performed in order to make shear wave on the bottom of aluminum alloyed pyramid. Also, a jig was manufactured and developed for generating a shear wave based on the computer numerical simulation. It is found that the experimentally shear wave variation of newly-designed jig is consistent with computer numerical simulation results and shear wave ultrasonic application can be very useful to detect the defects in CFRP composites. 作者: Author: Sun-Kyu KIM[1] David HSU[2] Young-Hwan SEO[3] Kwang-Hee IM[4] 作者单位: Division of Mechanical System Engineering,Chonbuk National University,Jeonju 561-756,KoreaCenter for Nondestructive Evaluation,Iowa State University,Ames,Iowa 50011,USADepartment of Physical Education,Chosun University,Kwangju 501-759,KoreaDepartment of Automotive Engineering,Woosuk University,490,Hujung-ri,Samrae-up,Wanju-ktm,Chonbuk,565-701,Korea 期 刊: 中国有色金属学报(英文版) ISTICEISCI Journal: TRANSACTIONS OF NONFERROUS METALS SOCIETY OF CHINA 年,卷(期): 2009, 19(z1) 分类号: Keywords: carbon-fiber reinforced plastics (CFRP) polarized mechanism stacking orientation defect composite laminates 机标分类号: V21 O1 机标关键词: composite laminates CFRP stacking shear waves simulation results isosceles triangle application based connected in order two found make made 基金项目:【Detection of stacking orientation er】相关文章:
