Tensile testing of \u00b145\u00b0 composite laminates is an economical and effective method for measuring in-plane shear strength. In this paper, the in-plane shear modulus of T800 carbon fiber\/epoxy composites were measured through tensile tests of \u00b145\u00b0 composite laminates, and acoustic emission (AE) was used to characterize the damage of laminates under in-plane shear loading. Factor analysis (FA) on acoustic emission parameters was performed and the reconstructed factor scores were clustered to obtain three damage patterns. Finally, the development and evolution of the three damage patterns were characterized based on the cumulative hits of acoustic emission. The maximum bearing capacity of the laminated plate is about 17.54 kN, and the average in-plane shear modulus is 5.42 GPa. The damage modes of laminates under in-plane shear behavior were divided into three types: matrix cracking, delamination and fiber\/matrix interface debonding, and fiber fracture. The characteristic parameter analysis of AE showed that the damage energy under in-plane shear is relatively low, mostly below 2000 mV \u00d7 ms, and the frequency is dispersed between 150\u2013350 kHz.<\/jats:p>","DOI":"10.3390\/polym15214319","type":"journal-article","created":{"date-parts":[[2023,11,3]],"date-time":"2023-11-03T10:51:28Z","timestamp":1699008688000},"page":"4319","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["A Study on Damage of T800 Carbon Fiber\/Epoxy Composites under In-Plane Shear Using Acoustic Emission and Digital Image Correlation"],"prefix":"10.3390","volume":"15","author":[{"given":"Zikai","family":"Lin","sequence":"first","affiliation":[{"name":"Shenzhong Link Management Center, Zhongshan 528400, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Changheng","family":"Shi","sequence":"additional","affiliation":[{"name":"Faculty of Civil Engineering and Mechanics, Jiangsu University, Zhenjiang 212013, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaochu","family":"Huang","sequence":"additional","affiliation":[{"name":"Shenzhong Link Management Center, Zhongshan 528400, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Can","family":"Tang","sequence":"additional","affiliation":[{"name":"College of Civil Science and Engineering, Yangzhou University, Yangzhou 225127, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ye","family":"Yuan","sequence":"additional","affiliation":[{"name":"School of Electrical and Information Engineering, Jiangsu University, Zhenjiang 212013, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,11,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"106879","DOI":"10.1016\/j.compositesa.2022.106879","article-title":"Novel thermomechanical characterization for shrinkage evolution of unidirectional semi-crystalline thermoplastic prepregs (PPS\/CF) in melt, rubbery and glassy states","volume":"156","author":"Golzar","year":"2022","journal-title":"Compos.
