2019 is coming to an end. What new applications have carbon fiber composites made in the fields of industry, transportation, aviation, and shipping this year? Let's review it together!
New application in official and passenger ships
At the China International Import Expo held at the China National Convention and Exhibition Center in Shanghai from November 5th to November 10th, 2019, the first exhibit exhibits-FSD195 high-speed official ship from Italian Ferretti Company, according to its chief engineer Luca Pelosio said that the official ship is 20 meters long and weighs about 37 tons. It uses a lot of new materials such as carbon fiber and titanium. The maximum speed exceeds 55 knots. It can last 525 nautical miles at a cruising speed of 35 knots. No fuel needed to drive to Xiamen.
In order to further improve the quality of the voyage, the domestic Shunde Passenger Transport Co., Ltd. invested 65.8 million yuan in the construction of the carbon fiber luxury high-speed passenger ship-"Xin Shun Shui", which officially sailed on the afternoon of November 14, 2019 in Shunde Hong Kong and Macau City. The passenger ship is 42.8 meters long and 10.8 meters wide, with a maximum speed of 37 knots. The new passenger ship uses a large number of new carbon fiber composite materials, which is 30% lighter than aluminum alloy ships of the same size and has a speed of more than 20%. It has the advantages of environmental protection, economic low carbon, safety and efficiency. The travel time of the passenger ship from Shunde to Hong Kong is only 1 hour and 50 minutes, which is more than 20 minutes shorter than before.
New application in new energy electric aircraft
The new energy electric aircraft RX4E aircraft independently developed by the Liaoning General Aviation Research Institute of Shenyang University of Aeronautics and Astronautics has successfully made its first flight not long ago. The RX4E aircraft optimizes the design of the whole aircraft structure, and uses engineering iteration and intelligent topology optimization based on accurate whole-machine balanced load And the combination of nonlinear design to achieve the integration of load and structural strength. A wide range of carbon fiber composite materials with light weight, high strength, and corrosion resistance are used. The carbon fiber composite material structure accounts for 77% of the total weight of the machine. Carbon fiber composite material structural parts adopt advanced processes such as wet vacuum bag forming and hot pressing tank forming, which ensure the production quality and mechanical properties of the product while controlling the production cost reasonably. Compared with the traditional metal structure aircraft, this application technology of carbon fiber composite material with integrated strength-structure-process design maximizes the structural efficiency of new energy aircraft.
New application in oilfield operation system
At the 21st China International Industry Fair, the “new efficient mechanical recovery system with carbon fiber and continuous sucker rod development as the core” jointly declared by Shanghai Petrochemical, Shengli Oilfield and Xinda Oilfield Xinda Pipeline Industry was jointly established for the first time China International Industry Fair Award (CIFF Award). "A new high-efficiency mechanical recovery system with carbon fiber and continuous sucker rod development as its core" is a system containing technology and equipment. The continuous sucker rod length of carbon fiber reinforced composite materials in this system can reach 5000 meters, which successfully overcomes the past Problems such as large power consumption during operation, easy corrosion, short service life, and long working time are required. At present, the system has been industrialized in 545 wells in 94 oilfield blocks in China, effectively improving economic efficiency. Among them, the application effects in the three directions of deep pumping and increasing oil consumption, energy saving and consumption reduction, and anticorrosion and longevity are remarkable, and have a good prospect of promotion and application.
New application in high-speed rail and other rail vehicles
The application of carbon fiber composite materials in high-speed rail and other rail vehicles is also gradually deepening. From interior parts to structural parts, the proportion of carbon fiber composite materials is also steadily increasing. This year, a certain type of high-speed rail vehicle tailored the driver's cab semi-enclosed structural frame body. The structural frame body includes a total of more than fifty parts. The largest part is 2.1 meters long. The application of the entire product will be the driver's cab Partly provides significant lightweight effects. It is reported that the control panel part of the carbon fiber driver's cab has been mass-produced, and the remaining semi-enclosed structural frame will also be widely used on high-speed rail vehicles within 2-3 years.
