Invention Reference Number
This invention introduces a continuous composite forming process that produces large parts with variable cross-sections and shapes, exceeding the size of the forming machine itself. This method significantly reduces production time, cost, and labor compared to traditional composite manufacturing processes like the vacuum-assisted resin transfer method (VARTM), while also allowing for greater control over part shape and design.
Description
The continuous composite forming process uses a roll of material that is fed into a heated chamber and formed into the desired shape by a belt roller system. The process allows for the creation of large, complex parts with variable cross-sections and 3D profiles, eliminating the need for costly, time-consuming molds. This innovation is designed to meet the needs of industries requiring large composite parts, such as aerospace and wind energy, where traditional methods like VARTM are slow, labor-intensive, and prone to defects. The invention offers a solution that is faster, more cost-effective, and capable of producing high-quality parts with minimal waste.
Benefits
- Scalable and flexible production: Capable of producing large parts with complex shapes without the need for multiple molds.
- Cost reduction: Eliminates the high capital expenditure associated with traditional mold-making processes.
- Defect reduction: Improved control over part shape and quality, reducing errors and waste.
- Reusability: The system can be used for different shapes, reducing the need for frequent mold changes.
Applications and Industries
- Aerospace: Producing complex and large composite parts for aircraft.
- Renewable energy: Enhancing the production of wind turbine blades.
- Marine industry: Manufacturing boat shells and other large marine components
