Abstract

Flexural and compressive failures of carbon fiber composites, more critical than direct tensile failure, imply T700 with higher tensile strength (about 40 % higher than T300) can still be outperformed by T300 in flexure and compression through careful composite microstructure designs. We show mechanical cross-linking from nano-/micro- Aramid Pulp (AP) fibers of a few hundred microns in length can be generated if the interleaving thickness is reduced to around or below 20 μm. Flexural properties of T300 with mechanical cross-linking from AP (4–6 g/m²) are more superior than those of T700, both before and after low energy impacts. Up to 40 % and up to 50 % increase in shear and flexural strengths were observed. This work compared flexural properties and impact resistance of T700 and AP toughened T300 composites, showing the importance of structural design (e.g. using thin layer interlayer AP cross-linking) for higher strength and toughness simultaneously.

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.
