Efficient Exothermic Press toward Ultrafast and Scalable Manufacturing of Complex Polymer Composites.

ABSTRACT: Rapid and scalable production of high-performance composites remains a key challenge in achieving sustainable manufacturing. Here, Exo-press frontal polymerization (EPFP), a novel and transformative method for manufacturing fiber-reinforced thermoset polymer composites, overcoming energy efficiency, scalability, and curing complex geometries, is introduced. Unlike conventional curing methods that require prolonged processing times and high energy, EPFP utilizes exothermic heat to reduce curing time from hours to minutes with minimal external energy. Combining exothermic heat with press molding, the novel EPFP enables the efficient fabrication of complex geometries, such as airfoil skin sections, with high fiber volume fractions (above 60%). In addition, EPFP is compatible with commercial o
