Compared to conventional composites, AM counterparts offer localised property control and rapid prototyping, yet their dynamic response remains underexplored. This study investigates the quasi-static and low-velocity impact bending of nylon-based AM composites reinforced with short and continuous carbon fibres. The effects of fibre type (short vs. continuous) and orientation (longitudinal, transverse, quasi-isotropic) were examined using three-point bending and pendulum impact tests at multiple energy levels. In addition, repeated-impact experiments were performed to assess durability and progressive damage. The obtained results show that fibre architecture strongly influences stiffness, strength, and energy absorption. Short-fibre composites exhibited higher initial flexural stiffness, while continuous-fibre laminates delivered superior strength and impact resistance. Under intermediate impacts, quasi-isotropic short-fibre configurations achieved a favourable balance between toughness and damage tolerance, despite their lower strength. At higher energies, continuous-fibre laminates absorbed more energy through complex fracture propagation. These findings highlight the importance of fibre continuity and orientation in tailoring the mechanical response and provide insight into the design of AM composites for impact-sensitive applications where toughness, manufacturability, and cost-effectiveness must be balanced.</div></div>","PeriodicalId":282,"journal":{"name":"Composites Part A: Applied Science and Manufacturing","volume":"202 ","pages":"Article 109446"},"PeriodicalIF":8.1,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145691699","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}

This work demonstrates the viability of hybrid biopolymer blends for creating low-density, high-performance materials from short-fibre textile waste with sustainable applications in insulative structural engineering.</div></div>","PeriodicalId":282,"journal":{"name":"Composites Part A: Applied Science and Manufacturing","volume":"202 ","pages":"Article 109459"},"PeriodicalIF":8.1,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145691693","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}
