Progress in surface modification preparation, interface characterization and properties of continuous carbon fiber reinforced polymer matrix composites

Abstract

ABSTRACT Additive manufacturing technology brings new revolutionary potential for the development of carbon fiber reinforced polymer composites. Continuous carbon fiber reinforced composites developed using fused deposition modeling technology have the characteristics of high specific strength, high specific modulus, light weight, and flexible design, which is the solution direction for low-cost, rapid, and flexible application of advanced composite materials in the future. In this paper, the preparation of continuous carbon fiber reinforced polymer composites with continuous carbon fibers as reinforcement and thermoplastic/thermoset as matrix, surface modification and their mechanical properties are investigated, the interfacial characteristics and properties of continuous carbon fiber reinforced polymer composites under different pretreatment processes, auxiliary processes and post-treatment processes are studied, and the connection between the micro-morphology and the mechanical properties of this composite is further analyzed. The direction of defect resolution of continuous carbon fiber reinforced polymer composites fabricated by fused deposition technology is provided, and the future development direction is envisioned.
