METHOD OF MAKING A FIBROUS PREFORM AND A FIBROUS PREFORM THUS OBTAINED - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240051257 titled 'METHOD OF MAKING A FIBROUS PREFORM AND A FIBROUS PREFORM THUS OBTAINED
Simplified Explanation
The patent application describes a method of making a fibrous preform using carbon fibers or fibers of a carbon precursor. The method involves superposing at least two layers of these fibers according to a predefined superposition axis to form a multilayer body. The multilayer body is then needle-punched in a direction parallel to the superposition axis to arrange the fibers parallel to the axis and create a needle-punched multilayer body. Multiple needle-punched multilayer bodies can be superposed with each other to further enhance the structure.
- The method involves layering carbon fibers or fibers of a carbon precursor to create a multilayer body.
- The multilayer body is then needle-punched in a direction parallel to the layering axis to align the fibers.
- Multiple needle-punched multilayer bodies can be combined to create a stronger structure.
Potential applications of this technology:
- Manufacturing of carbon fiber composites for aerospace and automotive industries.
- Production of high-strength materials for construction and infrastructure.
- Creation of lightweight and durable sporting goods such as tennis rackets and bicycles.
Problems solved by this technology:
- Provides a method for aligning carbon fibers in a specific direction, improving the strength and performance of the final product.
- Allows for the creation of complex fiber structures with controlled fiber orientation.
- Enhances the efficiency of fiber reinforcement processes.
Benefits of this technology:
- Increased strength and stiffness of carbon fiber composites.
- Improved control over fiber orientation, leading to optimized material properties.
- Enhanced manufacturing efficiency and cost-effectiveness.
Original Abstract Submitted
a method of making a fibrous preform in carbon and/or fibres of a carbon precursor may include superposing at least two layers of carbon fibres and/or fibres of a carbon precursor according to a predefined superposition axis z so as to form a multilayer body. the method may also include needle-punching via least one first needle-punching device the multilayer body in a needle-punching direction substantially parallel to the superposition axis z to arrange at least part of the fibres parallel to the superposition axis z, so as to obtain a needle-punched multilayer body. an optional step may include superposing with each other according to the superposition axis z two or more of the needle-punched multilayer bodies, obtained separately by applying the above steps.
