The composite molding process is an important part of the composite manufacturing process, and different molding processes are suitable for different composite materials and products. This article will briefly introduce 25 composite molding processes, including their characteristics, applications, and development trends.
1. Hand lay-up molding.
Hand lay-up molding is a traditional composite molding process suitable for the production of large, complex composite products. The hand lay-up molding process is simple and the cost is low, but the quality of the product is greatly affected by the technical level of workers.
2. Jet molding.
Jet molding is a fast and efficient composite molding process suitable for the production of small and medium-sized composite products. The jet molding process uses a spray gun to spray a mixture of resins and fibers onto the surface of the mold to quickly cure into a finished product.
3. Autoclave molding.
Autoclave molding is a high-temperature and high-pressure composite molding process, which is suitable for the production of high-performance composite products. The autoclave molding process places molds and fiber-reinforced materials into an autoclave and cures them into products at high temperatures and pressures.
Fourth, vacuum bag pressing.
Vacuum bagging is a composite molding process that uses vacuum bags to pressurize molds and fiber-reinforced materials, and is suitable for the production of composite products of various shapes and sizes. The vacuum bagging process can effectively eliminate air bubbles and voids and improve the quality of products.
5. Pultrusion.
Pultrusion is a continuously produced composite molding process suitable for the production of composite profiles with a wide range of cross-sectional shapes. The pultrusion process involves the continuous passage of fiber-reinforced materials and resins through a mold and cures them to form a finished product.
6. RTM molding.
RTM molding is a closed-mold pressurized composite molding process, which is suitable for the production of composite products of various shapes and sizes. The RTM molding process places fiber-reinforced materials and resins into a mold and then cures them into a finished product by applying pressure and heat.
7. LFT-D molding.
LFT-D molding is a molding process for long-fiber reinforced thermoplastic composites, which is suitable for the production of composite products of various shapes and sizes. The LFT-D molding process mixes a long fiber reinforced material and a thermoplastic resin and then continuously extrudes it to form a finished product.
8. LCP-D molding.
LCP-D molding is a molding process for liquid crystal polymer-reinforced thermoplastic composites, which is suitable for the production of composite products of various shapes and sizes. The LCP-D molding process mixes liquid crystal polymer reinforcement materials and thermoplastic resins and then continuously extrudes them to form a finished product.
9. 3D printing technology.
3D printing technology is a rapid prototyping technology based on digital models, which is suitable for the production of composite products of various shapes and sizes. 3D printing technology uses nozzles to stack a mixture of resins and fibers layer by layer.
10. Fused deposition technology.
Fused deposition technology is a rapid prototyping technology based on the molten state, which is suitable for the production of composite products of various shapes and sizes. Fused deposition technology uses a nozzle to stack a mixture of resins and fibers in a molten state layer by layer into a finished product.
11. SLS technology.
SLS technology is a rapid prototyping technology based on powder materials, which is suitable for the production of composite products of various shapes and sizes. SLS technology uses a laser beam to stack powder materials layer by layer into a finished product.
12. lamination lamination lamination lamination lamination molding is a composite molding process that stacks multiple layers of thin plates together and bonds them together by adhesives, which is suitable for the production of composite products of various shapes and sizes. This process can produce composite products with excellent mechanical properties, and the mechanical properties of the product can be adjusted by changing the arrangement of the thin plates.
