Inventory of new technological breakthroughs in the carbon fiber industry in 2021
Using laser technology to achieve high-strength connection of metal and carbon fiber reinforced thermoplastic composite materials
Carbon fiber and glass fiber reinforced thermoplastics (CFRTP/GFRTP), due to their low density, high specific strength and excellent chemical resistance, have been increasingly used to replace metals in many applications.
In actual CFRTP/GFRTP applications, it is difficult to achieve high-strength heterogeneous bonding between metals and thermoplastic composites. In order to meet this requirement, in the past few decades, many processes for combining metals and thermoplastics have been developed, including bonding, mechanical fastening, and thermal welding. A significant advantage of this technology is that it has a very high transconductance and the possibility of very high-speed operation. High electron mobility transistors (HEMT) use heterojunctions to operate at higher frequencies (over 500GHz). The correct doping strategy and energy band arrangement generate extremely high electron mobility by forming two-dimensional electron gas with minimal scattering in the undoped area.
Toray carbon fiber successfully used in the world's first flying car
In January 2021, the Dutch company PAL-V was approved to operate Liberty "flying cars" on the streets of Europe. PAL-V is an acronym for Personal Air and Land Vehicle, and Liberty is a rotorcraft. PAL-V Liberty rotor blades use 190gsm TORAYCA T700S/ #2510 fabric and 150gsm TORAYCA T700G/#2510 UD carbon fiber composite materials, provided by Toray composite materials America, Inc. (CMA). The body panels, doors and fuel tank use 200gsm TORAYCA T300/ER45 fabric, 300gsm TORAYCA T700/ER450 UD, and CK mixed carbon fiber and aramid fiber materials from Toray Composites (CIT) in Italy. Both CMA and CIT are subsidiaries of Toray Corporation.
Teijin and AEV develop LS-EV prototype
Teijin and AEV started joint research and development of LS-EV (Low Speed Electric Vehicle) in 2019. The result is the successful development of the "Blanc Robot", a multipurpose LS-EV platform that can be mounted on the vehicle body to respond to autonomous driving, and the LS- equipped with photo voltaic cells that uses Teijin's poly-carbonate resin "Panlite®" on the surface. Roof for EV. It combines Teijin’s cutting-edge technology and molding experience in the fields of lightweight, high-strength materials and processing with AEV’s basic design of LSEV, low-energy drive and control technologies and other technologies to design a prototype car under optimal conditions.

Ningbo, China realizes stable preparation of high-modulus and high-strength carbon fiber CNI QM55
September 16, 2021, undertaken by the high-performance carbon fiber and composite material team of Ningbo Institute of Materials, China. During the three-year implementation process, the research team made breakthroughs in response to the urgent need for localization of high-modulus and high-strength carbon fibers for near-space drones. Low-temperature graphitization technology has been adopted to realize the stable preparation of high-modulus and high-strength carbon fiber CNI QM55. Tests by domestic professional institutions have shown that the performance of the stable CNI QM55 carbon fiber is equivalent to that of similar foreign products. Subsequently, CNI QM55 carbon fiber was used to successfully complete the processing of the static test parts and deliverable of the main beam of the near-space UAV, and the delivery parts successfully completed the flight test.
The James Webb Space Telescope using high-modulus carbon fiber composite materials successfully lifted into space
On December 25th, the James Webb Space Telescope (JWST) jointly developed by NASA, the European Space Agency (ESA) and the Canadian Space Agency (CSA) has successfully Launched from Kuru, French Guiana. The James Webb telescope contains a variety of cutting-edge technologies, including Toray Advanced Composite's (TAC) innovative composite materials. TAC cooperated with Northrop Grumman Aerospace Corporation, according to its engineering and manufacturing tradition in the aerospace industry, selected high-quality, high-reliability composite materials for the structural design of optical telescope elements (OTE) , Integrated Scientific Instrument Module (ISIM) and Spacecraft Components (SCE).
Carbon Fiber Paper for Air Cathodes towards Flexible and Rechargeable Zn–Air Batteries
For the first time, researchers used the hydrothermal method to synthesize a thick mesoporous Co3O4 film in situ on the surface of cut carbon fibers (CFs). Then, the wet paper-making production process is used to produce carbon fiber paper (Co3O4/CP, carbon fiber paper) into a flexible zinc-air battery (ZAB). As one of the secondary battery systems, zinc-air battery (ZAB) has good operating characteristics, such as high specific capacity and current density, and is a suitable substitute for flexible energy storage batteries. Carbon fiber has excellent tensile strength, electrical conductivity and excellent flexibility, so it becomes an ideal choice to replace traditional graphite anodes. Due to low cost and abundant reserves, non-precious metal catalysts have begun to replace classic catalysts made of precious metals such as gold and ruthenium. These ultra-smooth paper composite electrode materials have great potential and will help to further accelerate the development of zinc-air batteries in the fields of different flexible and wearable energy storage devices.
