METHOD FOR PRODUCING A CERAMIC MATRIX COMPOSITE PART - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240018057 titled 'METHOD FOR PRODUCING A CERAMIC MATRIX COMPOSITE PART
Simplified Explanation
The abstract describes a method for producing a ceramic matrix composite part using core-shell particles and fiber preforms. The core-shell particles consist of a ceramic core and an adhesive shell that completely coats the core. These particles are then sintered in the fiber preform to form a ceramic matrix within its porosity.
- The method involves forming a fiber preform from fibrous structures, including core-shell particles.
- The core-shell particles have a ceramic core and an adhesive shell that coats the core.
- The adhesive shell defines the outer surface of the core-shell particles.
- The core-shell particles are completely coated with the adhesive, ensuring the core of ceramic material is fully covered.
- The sintering process of the core-shell particles in the fiber preform results in the formation of a ceramic matrix within the porosity of the preform.
Potential Applications:
- Aerospace industry: Ceramic matrix composites are lightweight and have high strength, making them suitable for aerospace applications such as aircraft components.
- Automotive industry: The use of ceramic matrix composites can improve fuel efficiency and reduce emissions in vehicles.
- Energy sector: Ceramic matrix composites can be used in high-temperature environments, making them suitable for applications in power generation and nuclear industries.
Problems Solved by this Technology:
- Traditional ceramic matrix composites may have issues with poor interfacial bonding between the fibers and the matrix, leading to reduced mechanical properties. The use of core-shell particles with adhesive shells helps to improve the bonding and enhance the overall performance of the composite.
- The method allows for the production of ceramic matrix composites with controlled porosity, which can be advantageous for specific applications that require a certain level of permeability or thermal insulation.
Benefits of this Technology:
- Improved mechanical properties: The use of core-shell particles with adhesive shells enhances the interfacial bonding between the fibers and the matrix, resulting in improved mechanical properties such as strength and toughness.
- Controlled porosity: The ability to control the porosity of the ceramic matrix composite allows for customization of the material's properties, making it suitable for a wide range of applications.
- Lightweight: Ceramic matrix composites are known for their lightweight nature, which can contribute to weight reduction in various industries, leading to improved fuel efficiency and performance.
