Material technology is one of the important guarantees for the advanced performance of weapons and equipment. It is the premise that triggers revolutionary changes in weapons and equipment. Every small step in the progress of material performance embodies the sweat wisdom of researchers and the feelings of serving the country. In China Aerospace Science and Technology The 306 of the Third Hospital has a research team for special materials. By 2018, the thermal structure has been established for 11 years. As an important professional direction in the thermal structure profession, carbon fiber reinforced carbon-based composites (C/C composite) Materials) The profession has also been established for more than eight years. In the past eight years, the flying people who are engaged in C/C composite materials have overcome all difficulties and have developed a road of development.
Seize the opportunity to achieve zero breakthrough in product engineering application
C/C composites are considered to be ideal ultra-high temperature composite materials, widely used in the preparation of ultra-high temperature components such as end, throat lining, gas rudder. Eight years ago, 306 thermal structure specialty, especially C/C composite material direction In the stage of construction and layout, all C/C composite thermal ablation component products of the Third Hospital must rely on the external association.
In 2012, after several years of technical accumulation and precipitation, 306 selected key personnel set up a product development team to promote C/C composite materials to practical engineering applications.
A type of material has a long way to go from basic research to engineering applications. There are many problems to be solved, and the difficulty and complexity are very large. For this team, many jobs are done for the first time. A lot of work can't be grasped. For this reason, the team starts with professional technology, repeatedly and deeply demonstrates the preparation scheme of high-performance C/C composite materials, and prepares detailed and reasonable process documents. In order to achieve perfection of the program, the process and quality are controllable, the team Fully carry forward the aerospace spirit, work overtime, repeat discussions, and not let go of any doubts; they also actively communicated to the design overall unit, the assembly plant, to ensure that all technical requirements are thoroughly understood, to avoid missing, and to eliminate non-technical obstacles.
After more than half a year of hard work, the team overcame many difficulties in product parts, complicated processes, long preparation cycles, conflicts in equipment resources, etc., and completed the development of C/C composite materials with high quality, and passed various test assessments. It is worth mentioning that the team not only guarantees the performance level of the product, but also achieves a significant reduction in product cost and price, which enables the design department to have more choices and contrasts in product planning and design, and improve the hospital. The independent support ability of related tasks.
After this battle, 306 achieved a breakthrough in the application of C/C composite product engineering, significantly improved the professional influence and expanded the professional development space.
Strive for excellence, build a reliable aerospace quality
The products have been applied in engineering, but the professional team did not meet this. They think more about how the process is continuously improved, how the densification efficiency is further improved, how the development cycle is further shortened, and how the cost is further reduced.
To this end, the team members took root in the whole line, followed the production process, and carried out in-depth process improvement. By formulating a more reasonable process machine plus solution, the C/C composite material was quickly and compactly shortened, shortening the product densification cycle and further reducing the cost; The assembly technology research has solved the difficulties of multi-part and complex structure product assembly technology. For the key of production key parts, it is required to formulate practical and feasible measures to ensure comprehensive monitoring of key requirements and lay a solid foundation for the smooth production of products. Solid foundation.
From 2013 to now, the team has developed a reasonable research and development plan to control the process in place, and has achieved many successful tests through multiple major tests. The product quality and reliability have been fully tested and verified, and it has been widely used by superior departments and brothers. Recognized, the team also won the honorary title of 'Aerospace Advanced QC Group'.
Service is supreme, the road to development is getting wider and wider
In the process of undertaking the development and production tasks, the professional team not only strictly controls the quality of the products, but also pays attention to the service guarantee, so as to think about the user's thoughts and urgent tasks.
Sometimes, the overall and final assembly tasks are very urgent, the schedule is very tight, and the test pieces are urgently needed for verification. After understanding the relevant situation, the team immediately organizes the research and overcomes the difficulties. At the first time, it tries to provide the test department and the final assembly unit with test products. The service guarantee work for the customer's emergency task was obtained, and the design overall and the customer's praise were obtained.
With a good reputation, there will be more customers and orders. With good product quality and follow-up service guarantee, 306 is more confident in the C/C composite product orders, often customers have found 306. The product application field has achieved a good development trend from single to series, from series to other models. The development path is getting wider and wider, the professional popularity is getting higher and higher, and the product quality reliability is more and more trusted by users.
Plan a blueprint, strive to achieve a greater leap
In the past few years, 306 C/C composite materials have overcome many difficulties, overcome one problem, and realized the C/C composite materials from scratch, from weak to strong. When they achieved results, they turned their attention to the long-term. The future - how much market to fight for, what higher requirements to target, what level to achieve, how to lay out in advance...
Looking forward to the future, this team will continue to maintain a spirit of hard work and forge ahead, never stop pursuing excellence, grow up with the Three Chambers in constant innovation, and move forward, grow and grow, and embrace a more brilliant and better future!
