1. Autoclave Molding
Process Principle:
Autoclave molding involves laying prepreg (pre-impregnated carbon fiber and resin) onto a mold, sealing it in a vacuum bag, and curing it under high temperature and pressure (0.5–1.5 MPa) inside an autoclave.
Advantages:
High-quality output: Uniform pressure and temperature reduce porosity, enhancing density and mechanical properties.
Complex geometry: Suitable for large, curved components (e.g., aircraft wings, satellite structures).
Consistent performance: Full resin curing ensures high strength and fatigue resistance.
Disadvantages:
High cost: Expensive autoclave equipment, high energy consumption, and additional vacuum systems.
Long cycle time: Slow heating/cooling phases reduce production efficiency.
Size limitations: Restricted by autoclave chamber dimensions.
Applications: High-performance aerospace components.
2. Compression Molding
Process Principle:
Compression molding places carbon fiber prepreg or chopped fibers mixed with resin into a metal mold, applying high heat and pressure (5–20 MPa) for curing.
Advantages:
High efficiency: Fast cycle time, ideal for mass production (e.g., automotive parts).
Precision: Tight tolerances and smooth surfaces due to precision molds.
Material efficiency: Minimal waste, suitable for standardized production.
Disadvantages:
High mold cost: Complex molds are expensive, uneconomical for small batches.
Design limitations: Struggles with deep cavities, thin walls, or complex 3D shapes.
Uneven pressure risk: Potential resin distribution issues in thick or large parts.
Applications: Automotive, sports equipment, and standardized industrial products.
