Abstract
Polymer-ceramic composites are widely used in electronic devices, biomedical engineering and other applications. This paper presents the results of an experimental study on the effects of silane coating on the fracture properties of epoxy-alumina composite. Mechanical testing coupled with micro X-ray computed tomography (micro-CT) was performed to investigate epoxy-alumina composite’s fracture behaviors. The matrix-particle interface was shown to be the weakest link in non-coated composites. Guided by the discovery, silane coating was applied to the particles to enhance the matrix-particle interfacial adhesion. The occurrence of matrix-particle interface debonding was reduced and delayed for composites with silane treatment on the particle surfaces. Ultimately, the fracture toughness and crack growth resistance of the composites were improved.
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.
