Abstract

The objective of this study is to characterize the role of glass fiber (GF) surface treatment in hydrothermal aging at polybutylene terephthalate (PBT) and GF interfaces from X-ray photoelectron spectroscopy analysis of the fracture surface. The mechanical properties of PBT/GF were investigated using four types of GFs treated with aminosilane and epoxy. The surface treatment containing epoxy contributed to the suppression of GF fracture during molding process and improved the interfacial strength with PBT, resulting in higher tensile strength of the PBT/GF before hydrothermal treatment. After hydrothermal treatment, the tensile strength of the epoxy-treated GF and PBT composites reduced owing to moisture absorption, and that of the aminosilane-treated GF and PBT composites decreased by hydrolysis at the interphase. Nevertheless, in the PBT/GF treated with epoxy and aminosilane together, the interfacial hydrolysis and moisture absorption during the hydrothermal treatment were suppressed, resulting in the highest tensile strength of PBT/GF.

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.
