The effect of nano-scale SiO<sub>2</sub> flow agent content on the powder flowability and the mechanical property of LPBF-CF/PEEK composites is analyzed.

Further, the orthotropic behaviors of LPBF-CF/PEEK composites are evaluated. Uniaxial tension, compression, and pure shear tests are conducted along three principal directions, i.e., the powder spreading direction, transverse direction, and building direction for LPBF-CF/PEEK composites. Excellent mechanical performance is observed along all loading conditions, except for the tension in the building direction. A macro-scale constitutive model, combining the Liu-Huang-Stout yield criterion and the associated flow rule, is developed to characterize the elastoplastic behaviors of LPBF-CF/PEEK composites. The model is calibrated using the uniaxial loading data of LPBF-CF/PEEK composites, and validated with the LPBF-CF/PEEK structures featuring triply periodic minimal surface (TPMS).</div></div>","PeriodicalId":282,"journal":{"name":"Composites Part A: Applied Science and Manufacturing","volume":"196 ","pages":"Article 109013"},"PeriodicalIF":8.1,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143928395","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}

The two polymers were applied by fluid coating from polymer solutions at different coating speeds. Scanning electron microscopy revealed smooth and high quality coatings for both polymers at low coating speeds.

As a result, the TiC particles were refined from aggregation with 10 μ m in the feedstock to nanoparticles with an average size of 58 nm, achieving uniform dispersion in the matrix. Homogeneous equiaxed grains with an average size of 0.75 μm were also achieved due to the low thermal cycle, dynamic recrystallization, and Zener pinning of TiC nanoparticles. Sub-microscale equiaxed grains and TiC nanoparticles allowed for strong grain refinement and Orowan strengthening, significantly enhancing the mechanical performance. Consequently, the as-built state composite exhibited an average yield strength of 203 MPa, an ultimate tensile strength of 291 MPa, and a uniform elongation of 13.2 %. This work provides a promising insight into aluminum matrix composite with homogeneous dispersed and nanoscale reinforcement, which is critical for advanced structural applications.</div></div>","PeriodicalId":282,"journal":{"name":"Composites Part A: Applied Science and Manufacturing","volume":"196 ","pages":"Article 109009"},"PeriodicalIF":8.1,"publicationDate":"2025-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143913059","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}
