"Aluminum is light but too soft, and ceramics are hard but fragile. Can the two be combined to form a new material that is both strong and light?"
In 2008, a high-performance ceramic-reinforced aluminum-based composite material with completely independent intellectual property rights-nano-SiC ceramic particle-reinforced aluminum-based composite material was successfully developed in AHTL Advanced Materials Technology Group.
Nano-SiC ceramic particle reinforced aluminum matrix composites have the characteristics of high strength, light weight, temperature and labor resistance, shock absorption and low expansion, and easy work and plasticity.
After more than ten years of process improvement and application promotion, at present, nano-SiC ceramic particle reinforced aluminum-based composite materials have been successfully applied to China's aerospace, military and industrial fields.
In the aerospace field, high-performance structural parts made of nano-SiC ceramic particles reinforced aluminum-based composite materials have been successfully applied to satellites such as "Tiangong-1", "Tiangong-2", "Mozi", and "Fengyun-4". In the development process of China's C919 large aircraft, its anti-fatigue properties surpassed that of American aluminum-lithium alloy materials. Nano-SiC ceramic particle-reinforced aluminum-based composite flooring and support beams have passed various static and dynamic tests of COMAC. A new generation of aviation materials with completely independent intellectual property rights solves the situation that the main materials of large aircraft rely on imports.
Nano-SiC ceramic particles reinforced aluminum-based composite high-performance pistons.
Nano-SiC ceramic particle-reinforced aluminum-based composite pistons have reached the highest level in the world in terms of high-temperature strength and fatigue strength, and are more than 10% ahead of the most advanced pistons in the international market, completely breaking foreign technology in high-power engine pistons. The blockade has realized the completely independent production of high-end pistons.
In the fields of China's high-speed rail and automobiles, nano-SiC ceramic particles reinforced aluminum-based composite materials are bringing about revolutionary changes in lightweight.
AHTL will build a new production line of nano-SiC ceramic particle-reinforced aluminum-based composite precision structural parts in 2020, which will have an annual production capacity of 30,000 tons of nano-SiC ceramic particle-reinforced aluminum-based composite materials and precision structural parts.
At present, it has an annual output of 30 tons of nano-SiC ceramic particle-reinforced aluminum-based composite material 3D printing powder, an annual output of 260,000 sets of nano-SiC ceramic particle-reinforced aluminum-based composite material automotive lightweight parts, and an annual output of 500,000 nano-SiC ceramic particle-reinforced aluminum High-performance piston production capacity based on composite materials.
Two production lines of nano-SiC ceramic particle-reinforced aluminum-based composite materials for automotive lightweight parts are under construction, and 17 automatic nano-SiC ceramic particle-reinforced aluminum-based composite piston production lines are under construction. After reaching full capacity, an annual output of 5 million nano-SiC ceramic particles reinforced Aluminum-based composite high-performance pistons, 1.5 million sets of nano-SiC ceramic particles reinforced aluminum-based composite automotive parts.
In July of this year, the aerospace materials production base of nano-SiC ceramic particle-reinforced aluminum-based composite materials with an annual output of 45,000 tons of aerospace-use nano-SiC ceramic particle-reinforced aluminum-based composite materials production line project has been officially put into operation.
