However, the lack of comprehensive understanding of the behavior and transformation of sizing agents during composite processing limits the performance enhancement of the composites. In this study, the interfacial mechanisms of sizing agents are systematically analyzed, distinguishing between chemical bonding and physical interaction pathways, while addressing the stages of wetting, molecular diffusion, and interfacial crosslinking. By optimizing the balance between chemical and physical interfacial mechanisms, significant improvements in stress distribution and filler-matrix compatibility are achieved. A quantitative relationship between sizing agent concentration and interfacial evolution was established, enabling precise control of the interface formation stages, including diffusion and crosslinking. The thermal conductivity of the optimized CF/TPI composites is 490% of that of PI. When used as a heat sink, it reduces the LED center temperature by 26 °C, while maintaining a tensile strength of 73 MPa and a retention rate of 69% at 200 °C. These results indicate that the precise control of the sizing process improved stress transfer across the interface, reduced microstructural defects, and contributed to enhanced thermal management and structural durability. This work provides a novel perspective on the dynamic role of sizing agents in composite development and lays the groundwork for advanced design strategies to maximize the performance of polymer composites.</div></div>","PeriodicalId":283,"journal":{"name":"Composites Science and Technology","volume":"266 ","pages":"Article 111174"},"PeriodicalIF":8.3,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143748329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper aims to investigate the effect of open holes on the failure behavior and strength of DD laminates.

In contrast, DD laminates demonstrate an inverse size effect, where their strength ultimately exceeds that of the corresponding QUAD laminates when the hole diameter is the largest. This phenomenon is closely tied to the evolution of damage mechanism as the geometric size changes, in which different roles of sub-critical damage events in the final failure of QUAD and DD laminates were discovered.</div></div>","PeriodicalId":283,"journal":{"name":"Composites Science and Technology","volume":"266 ","pages":"Article 111158"},"PeriodicalIF":8.3,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143738473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a multiscale experimental and simulation investigation of the curing effects on the individual Z-pin bridging behaviors and the mode Ⅰ interlaminar fracture of multi-pinned laminates by changing holding temperatures and times of cure. The results reveal that a low holding temperature for a long time decreases the cure-induced Z-pin/composite interfacial cracks, thus generating larger Z-pin energy dissipation and a better specimen's load-carrying capacity.

Fabricating rigid-flexible structures on glass fibers is a strategy to establish robust interfaces in GFRPs. However, the rigid components that consist of nanoparticles usually suffers from agglomerating during the process of GFRPs production, leading to low interfacial strength. In this work, we designed novel rigid-flexible structures on glass fibers by sizing method, and focused on preventing rigid components of rigid-flexible structures from agglomerating. Semi-interpenetrating polymer networks (semi-IPNs) as flexible components of rigid-flexible structures could anchor cellulose nanofibers as rigid components by hydrogen bonding to prevent cellulose nanofibers from agglomerating, thus strengthen the penetration of glass fiber and matrix resin. The uniformly dispersed cellulose nanofibers could deflect cracks and improve modulus to balance modulus difference between glass fibers and matrix resin. As a result, interfacial shear strength (IFSS) and transverse fiber bundle tension (TFBT) strength of GFRPs improved from 36.43 MPa to 48.60 MPa, from 34.43 MPa to 49.39 MPa, respectively.
