Description

Technical Field

[0001] The present invention relates to the technical field of ultra-thin layer toughened fiber reinforced composite materials, and in particular to a device and method for preparing a micron-level controllably arranged ultra-thin layer composite material. Background Art

[0002] Ultra-Thin Layer Fiber-Reinforced Composites (UTL-FRCs) are composite materials formed by ultra-thin layers of fiber prepreg. This material combines the high strength and high modulus properties of the fiber with the toughness and impact resistance of the matrix material, and shows broad application prospects in aerospace, automotive industry, electronic devices, biomedicine and other fields.

[0003] In the aerospace field, UTL-FRCs are widely used in aircraft structural parts, satellite components and rocket casings, significantly improving the performance and fuel efficiency of aircraft; in the automotive industry, UTL-FRCs are used to manufacture vehicle bodies, chassis and internal components, which can reduce vehicle weight and improve fuel economy and safety performance; in the field of electronic devices, UTL-FRCs are used in flexible circuit boards, sensors and energy storage devices, with light weight, high conductivity and good mechanical properties; in the biomedical field, UTL-FRCs are used to manufacture implants, artificial bones and joints with good biocompatibility, which can provide better mechanical support and functional performance.

[0004] At present, the research on ultra-thin layer fiber reinforced composites mainly focuses on four aspects: material design, manufacturing process, performance optimization and application expansion. In terms of material design, researchers are developing UTL-FRCs with multifunctional properties, such as self-healing, sensing, conductivity and thermal management functions. At the same time, the mechanical properties and functional properties of composite materials are further improved by introducing nanomaterials (such as graphene and carbon nanotubes). In terms of manufacturing process, the development of precision manufacturing technologies such as automated wire laying and automated tape laying has significantly improved the manufacturing accuracy and efficiency of composite materials. These technologies not only improve production efficiency, but also ensure product consistency and quality. In addition, green manufacturing is also a hot topic in current research. By developing environmentally friendly manufacturing processes and materials, the environmental impact of the manufacturing process can be reduced and sustainable development can be promoted.

[0005] In short, ultra-thin fiber-reinforced composites combine the high strength and high modulus of fibers with the toughness and durability of matrix materials, showing broad application prospects. Current research focuses on material design, manufacturing processes, performance optimization and application expansion, striving to develop composite materials with higher performance and versatility to meet the growing needs of various industries. With the continuous advancement of science and technology, ultra-thin fiber-reinforced composites will be used in more fields and provide new impetus for the development of modern industry and technology.

[0006] Ultra-thin fiber-reinforced composite materials play an important role in many high-tech and industrial fields due to their excellent mechanical properties, light weight, corrosion resistance and chemical resistance.
