Abstract
Additive manufacturing of fiber-reinforced polymer matrix composites enables the production of high-strength, low-weight structures for aerospace and industrial applications, but their performance is often degraded by deficient bonding at the polymer matrix-fiber interface. This study explores reinforcement processing, interfacial bonding, and modeling strategies that govern composite strength and reliability on the basis of a a literature review. Short and continuous fiber composites are contrasted among different AM processes where the stress transfer is reduced due to poor wetting, voids, and pull-out of fibers. Post-processing approaches like annealing and vacuum compression are presented to improve bonding and structural properties, and finite element and cohesive zone models provide understanding of interfacial behavior. Directions of this work in the future include smart printing systems for real-time observation, data-driven optimization, and standardized testing. This work points out interfacial bonding as a major factor in the evolution of structural performance of additively manufactured polymer composites.
