High-end, new fasteners are the advantages of future aviation fasteners

At 5:58 on November 1, 2011, Beijing time, China's self-developed Shenzhou-8 spacecraft launched its launch at the Jiuquan Satellite Launch Center and successfully entered the scheduled orbit 583 seconds later.

With the rapid development of the aerospace industry, the aviation fastener industry has ushered in an unprecedented era. Fasteners are widely distributed in aircraft. For example, there are about 400,000 fuselage and wings on a typical dual-aisle aircraft. From smart fasteners to high-performance grooved fasteners, fastener companies should Respond to the needs and opportunities of this market.

Titanium fasteners play a crucial role in the rendezvous and docking of the Tiangong-1 and Shenzhou-8. The new titanium alloy materials also become short boards that restrict high-end fasteners in China. The China Aerospace Science and Industry Corporation, with its superb level of manufacturing, has supported the flying dream of the Chinese nation through high-end fasteners. For all fastener designers and manufacturers, acquiring new materials such as titanium alloys is a major challenge. Rare material costs are currently rising. Today's aviation market is developing rapidly. The availability of raw materials is the most important one. The key factor is to provide customers with a proper delivery date.

Airbus and Boeing suddenly accelerated their development plans. As a result, the fastener industry has not yet been adequately prepared. In the past, it took a year to develop new fasteners, but now it is required to shorten it to several months. Boeing felt that fasteners were a real obstacle. Shortage of fasteners was a major factor in delays in the Boeing 787 test flight. This problem has brought risks to the long-term operation of the 787 airliner. The wave of aviation plans and the use of composite materials have played a positive role in the cooperation and advance planning of fastener design.

After 20 years of development, China’s aviation industry has been able to produce a variety of titanium alloy fasteners, but its types, specifications, and equipment capabilities are limited. Under the rapid development of international aviation, there is an urgent need to develop new materials and develop new types of fastening. Parts and expander production capacity to fill gaps in current aerospace assembly requirements.
