In MCC tests, the TMP-IPDA-Si displayed low THR (8.5 kJ g<sup>−1</sup>) and PHRR (170.5 W g<sup>−1</sup>) value.

As the power density of electronic devices continues to increase, the limitations posed by low thermal conductivity have led to traditional heat spreaders, such as metals and ceramics, gradually falling short of meeting actual usage requirements. Thanks to the excellent thermal conductivity, mechanical properties and tunability of thermal expansion coefficient, diamond composites based heat spreaders have recently garnered extensive attention and research. However, systematic summary and review of advanced diamond composites heat spreaders are lacking, which is not conducive to actively promoting the development of this field. Herein, we conduct an in-depth review of advanced diamond composites with the aim of exploring its application value as heat spreaders. First, the theoretical background of diamond composites is presented. Subsequently, current mainstream preparation methods for diamond composites are introduced. Following this, advanced diamond composites are discussed, with a focus on the latest breakthroughs in improving thermal properties. Finally, reliability tests are explored to guide the practical application of diamond composites as heat spreaders.

Warpage deformations in asymmetric cross-ply laminates after autoclave fabrication were measured over 84 days under controlled conditions (60 °C and 50%RH). A finite element analysis integrating anisotropic viscoelastic constitutive law and geometric nonlinearity was conducted to predict the PID and LTD using the material properties derived from the lamina-level thermomechanical analysis and dynamic mechanical analysis (DMA). The experimental results revealed that T700G/LM-PAEK exhibited a larger PID, which was attributed to its larger thermal strain and higher modulus during molding. In contrast, T700G/2510 exhibited a larger LTD, which was attributed to its higher sensitivity to moisture absorption. Although incorporating a moisture-sensitive shift factor was required for predicting the LTD of T700G/2510, the simulation accurately reproduced the PID and LTD for both materials. To validate the deformation simulation and provide insights into the viscoelastic behavior of the resin in aerospace-grade commercial prepregs with undisclosed chemical compositions, a self-consistent micromechanics model was further employed. This model estimated the equivalent viscoelastic properties of the resin from lamina-level DMA data. The findings demonstrated that both macroscale deformation prediction and microscale resin characterization can be achieved using only standard DMA tests on such prepregs.</div></div>","PeriodicalId":282,"journal":{"name":"Composites Part A: Applied Science and Manufacturing","volume":"196 ","pages":"Article 108963"},"PeriodicalIF":8.1,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143937521","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}
