Employing a novel Benchtop-AFP setup and ultrasonic Non-Destructive Testing (NDT), the study examined the internal structure of pristine, defective, and reworked composite specimens. A linear ultrasonic phased array roller probe captured through-thickness B-scans, revealing out-of-plane ply waviness. Artificially generated double gap/overlap defects were manually reworked using documented best practices. A remedial approach removed defective tows with minimal interference, followed by redeposition of correctly aligned tows. Ply topology was analysed using metrics including Root Mean Squared (RMS) waviness, peak-to-peak waviness, and average waviness height. Results demonstrated that reworked specimens exhibit residual out-of-plane waviness, with RMS waviness positioned between pristine and defective specimens. Notably, reworked specimens showed increased peak-to-peak waviness compared to pristine samples. Significant variability was observed, with some reworked specimens approaching pristine characteristics while others remained closer to defective states. This study emphasises the need to optimise rework procedures and establish robust quality control metrics in advanced composite manufacturing. The research also validates ultrasonic NDT’s effectiveness in characterizing out-of-plane defects and highlights the potential of cost-effective Benchtop-AFP setups for future research and development.</div></div>","PeriodicalId":282,"journal":{"name":"Composites Part A: Applied Science and Manufacturing","volume":"198 ","pages":"Article 109081"},"PeriodicalIF":8.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144205107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we propose a deep learning-assisted inverse design framework, called the Denoising Diffusion Probabilistic Model with Frequency-aware feature Fusion and External Attention module (DDPM-FFEA), to generate new nacreous microstructures meeting excellent specific damping performance. The frequency-aware feature fusion and external attention module are integrated into DDPM to provide more accurate spatial boundary features and a larger structural design domain, making the DDPM-FFEA framework suitable for designing nacreous composites with clear feature consistency and boundary definition within a limited design domain. The DDPM-FFEA inverse model is trained to highlight nacreous composites with counterintuitive asymmetric microstructures by specifying ultrahigh specific damping property. By studying various asymmetric microstructures, the ultra-high specific damping performance is attributed to the tensile-bending coupling effect. Microstructural asymmetry becomes a key morphological feature in damping materials, which may explain why asymmetry-induced gradient materials are widely present in natural materials.</div></div>","PeriodicalId":282,"journal":{"name":"Composites Part A: Applied Science and Manufacturing","volume":"198 ","pages":"Article 109050"},"PeriodicalIF":8.1,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144190495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
