Advancements in the Production of Continuous Carbon Fiber-Reinforced Thermoplastic Prepregs
1. Novelty in Impregnation Techniques Conventional methods, when handling high-viscosity thermoplastic resins, often fall short in terms of resin flow and fiber wetting. To address this, researchers have introduced the suspended hot melt technique and ultrasonic-assisted impregnation. The suspended hot melt method disperses resin powder in an aqueous suspension, leveraging ultrasonic cavitation to expand fiber […]
