Prepreg Machine
Prepreg machines (prepreg production lines) are the core specialized equipment for manufacturing resin-based prepregs. By uniformly coating resin onto fibers (such as carbon fiber and glass fiber) or fabrics, followed by heating, lamination, cooling, and winding, they produce prepregs with precise resin content and uniform fiber orientation—making them a critical upstream component in composite material molding.

Product Description
Product Overview
Prepreg machines (prepreg production lines) are the core specialized equipment for manufacturing resin-based prepregs. By uniformly coating resin onto fibers (such as carbon fiber and glass fiber) or fabrics, followed by heating, lamination, cooling, and winding, they produce prepregs with precise resin content and uniform fiber orientation—making them a critical upstream component in composite material molding.
Core Processes and Structure
Core Process: A dry hot-melt process is employed, comprising three major core steps: resin film formation, fiber spreading, and thermal-pressure lamination.
Key components: yarn feeding/unwinding system, resin coating system, yarn spreading system, thermal press laminating roller set, cooling system, and constant-tension winding system.
Precision Control: High-precision resin coating, precise gap control, and constant-tension control ensure uniform prepreg thickness and excellent batch-to-batch consistency.
Core Advantages
Stable product quality: the prepreg exhibits uniform resin content and wrinkle-free fibers, meeting the quality standards of high-end industries.
High adaptability: capable of producing unidirectional prepregs and fabric pre-pregs, compatible with a wide range of resin systems and fiber types.
High degree of automation: Fully automated production with integrated online inspection systems, resulting in high production efficiency and low labor costs.
Energy-saving and environmentally friendly: Adopts a closed-loop heating system with no solvent emissions, meeting environmental protection requirements and featuring low energy consumption.
Typical Application Scenarios
Aerospace: Prepregs for Composite Aircraft Components, Prepregs for UAV Structural Components
Wind Power Energy: Large-Tow Carbon Fiber Prepreg for Wind Turbine Blades
Sports Equipment: Prepreg for Carbon Fiber Rackets, Bicycle Frames, and Other Sports Gear
Industrial Applications: Automotive Lightweighting and Composite Prepregs for Industrial Equipment
