Abstract

Traditional shaping and curing of continuous fiber composites is an equipment, time, labor, and energy intensive process. This work investigates the integration of frontal polymerization (FP) with additively printed continuous-fiber tows to produce composite structures with controlled curvature. We combine the patterned tows with frontally polymerizable gel of poly(dicyclopentadiene) (pDCPD) to achieve rapid, autonomous, energy efficient, and predictable 3D curvatures, referred to as morphogenic composites. Due to the transient wave-like nature of FP, the propagation direction of the reaction front provides an additional means to vary the final shape of the morphed composite part. Digital image correlation and numerical simulation are used to quantify the influence of the transient strain effects, initiation locations, and front propagation paths on the composite’s final 3D shape. Overall, morphogenic composites can be autonomously and rapidly morphed to predictable and diverse 3D shapes through frontal polymerization with low energy and without tooling.

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.
