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.
