Advancements and Challenges in the Carbon Fiber-Reinforced Polymer (CFRP) Trimming Process

Abstract

In this review, we comprehensively examine the carbon fiber-reinforced polymer (CFRP) trimming process, covering both conventional machining techniques and novel approaches. We explore various methods, including conventional cutting, laser beam machining, robot arm machining, electrical discharge machining, and ultrasonic machining; we assess their respective strengths and limitations in the fabrication of CFRP components. We evaluate the effectiveness of each approach with respect to accuracy, surface integrity, defect occurrence, and productivity. Moreover, we explore the latest advancements and emerging trends in CFRP trimming processes, emphasizing the potential for improved efficiency and quality. The insights from this review support an in-depth understanding of the benefits and limitations of various trimming methods, providing valuable guidance for researchers and industry professionals in the selection of an optimal approach for CFRP component production.
