Abstract
In this study, the influence of carbon fiber reinforced thermoplastics (CFRTP) anisotropy on the performance of Ti-6Al-4 V (TC4)/CFRTP joints was investigated through experiments and simulations. In particular, a new meso-macro cross-scale thermal model was proposed for the laser joining of TC4/CFRTP. In meso-scale simulations, using a Fiber-PPS (polyphenylene sulfide) Representative Volume Element (RVE) model, CFRTP’s thermal properties were obtained, ranging from 25 ℃ to 3000 ℃. These results were then applied to calculate the macro-scale temperature distribution of TC4/CFRTP joints. The simulated joint features closely matched experimental observations, with an error of less than 5% in cross-section and interface morphology. Compared to the common simulation method, this method can effectively capture the influence of CFRTP anisotropy on temperature distribution, enabling precise strength analysis. In the experiments, two TC4/CFRTP joints were designed: Joint A, with carbon fibers at the interface perpendicular to the laser joining direction, and Joint B, with fibers parallel to it. The joint strength of Joint A was found to be 1.706 times that of Joint B. Experimental and simulation results indicated that carbon fibers perpendicular to the joining direction enhance interfacial heat transfer capability from the joining center to both sides, reducing energy aggregation in the central bonding area, decreasing pyrolysis zone and pores, and promoting thorough CFRTP melting near the interface for stronger bonding.
期刊介绍：
Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field.
The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest.
Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials.
Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
