Abstract

The study demonstrates the development of a novel and sustainable sizing agent to improve the mechanical properties and compatibility of E-glass fibers (EGF) in cement composites. The sizing agent comprises chitosan (a biopolymer), graphene oxide and a calcium precursor. The graphene oxide and calcium ions help reinforce and crosslink chitosan fibers, enhancing the composite’s mechanical strength and bonding with the cement matrix. The tensile strength and the fracture strain of modified EGFs increased by 1.47 and 1.52 times, respectively. Due to the high deformation capability of the composite, the study revealed that the coating remains intact until the glass fiber fractures. Digital image correlation measurements on GFRC specimens confirm a strong bond between the coating and concrete matrix. The XPS and ATR-IR spectroscopy analyses confirm the interaction between surface-modified EGFs and cement matrix. The nanocomposite offers a sustainable alternative to conventional sizing employed in EGFs for GFRC applications.

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.
