Abstract

The effect of micro-size core–shell particles (CSPs) dispersion in-between the plies of CF/PA6 laminates on its tension–tension (T–T) fatigue performance is studied. The CSPs were dispersed using two different dispersion methods, namely: a sieve-assisted process and a pump-assisted process at ply the interfaces. The heat-assisted compression molding was used to fabricate the laminates. Baseline tensile and T–T fatigue tests were conducted to compare performance of the laminates fabricated using these two methods and analyzed based on the S-N curve, stiffness degradation, and energy dissipation. It was observed that the uniform CSPs dispersion improved the tensile strength and fatigue life respectively by 1.1 and 3 times, when pump-assisted dispersion was used. Furthermore, through the statistical reliability study of tensile data, it was observed that the pump-assisted method is better, more reliable, and consistent. The fatigue test results also showed that both dispersion methods affect the stiffness degradation and energy dissipation significantly.

期刊介绍： Composites Part A: Applied Science and Manufacturing is a comprehensive journal that publishes original research papers, review articles, case studies, short communications, and letters covering various aspects of composite materials science and technology. This includes fibrous and particulate reinforcements in polymeric, metallic, and ceramic matrices, as well as 'natural' composites like wood and biological materials. The journal addresses topics such as properties, design, and manufacture of reinforcing fibers and particles, novel architectures and concepts, multifunctional composites, advancements in fabrication and processing, manufacturing science, process modeling, experimental mechanics, microstructural characterization, interfaces, prediction and measurement of mechanical, physical, and chemical behavior, and performance in service. Additionally, articles on economic and commercial aspects, design, and case studies are welcomed. All submissions undergo rigorous peer review to ensure they contribute significantly and innovatively, maintaining high standards for content and presentation. The editorial team aims to expedite the review process for prompt publication.
