Tsinghua students won the champion of the third ultralight composite bridge competition

from October 26 to 28, the third ultralight composite bridge/wing student competition was held in Tianjin Binhai Convention and Exhibition Center. After fierce competition, the second team of Tsinghua University performed well in the plant fiber bridge group competition, and won the first place in the natural plant fiber bridge group with an excellent score of 13.48 (self weight 645.6g, ultimate load 8702.8n); The first team of Tsinghua University who participated in the carbon fiber bridge group won the third prize for the best video display

this competition brought together 51 teams from more than 10 colleges and universities, including Tsinghua University, Shanghai Jiaotong University, Tongji University, Beijing University of Aeronautics and Astronautics, Harbin Engineering University, Northwest University of technology, Donghua University, Nanjing University of Aeronautics and Astronautics, Nanjing University of technology and so on. Nearly 200 students participated in the competition, covering composite materials, mechanics, aerospace and other related professional fields. The two teams sent by Tsinghua University are graduate students from the composite engineering structure research group of the Department of civil engineering

also put forward suggestions on the extension of the warranty period of polypropylene and the establishment of the loading point inspection record form

this competition is co sponsored by China Aviation Industry Corporation, the society for the advancement of material and process engineering (SAMPE) Beijing Branch, SAMPE Shanghai branch and China Aviation society, and supported by Boeing of the United States. The competition is divided into wings, carbon fiber bridges Three groups of natural fiber bridges. The participating students use the drawings provided by the competition organizing committee and the core materials, fabrics and other materials in the toolkit to design and manufacture a composite wing or bridge. The midspan loading test under simple support conditions is carried out on site, and the ratio of the maximum load to the midspan deflection is calculated. The one with the largest ratio wins. In addition, the competition also selected the best craft appearance award, the best Poster Award and the best video display award

the ultralight composite wing competition has been held for 6 times during the SAMPE American annual meeting, while the ultralight composite bridge competition has been held for 14 times. The students participating in the competition designed and manufactured a composite wing and bridge by using the drawings provided by the Organizing Committee and the core materials, fabrics and other materials in the toolkit. The wing and bridge with the highest load to weight ratio, that is, the one with the largest load to weight ratio, won the test on site

in China, the super light composite bridge/wing manufacturing student competition has been held twice in Tianjin and Shanghai respectively. The competition is mainly for students from Chinese universities and scientific research institutions. The competition aims to popularize the knowledge of material structure design of advanced composite HP that will not enter this market, and improve the students' ability to analyze and deal with problems, especially to build the world's first 10000 ton trans isoprene rubber device in China. On the one hand, the activity built an international stage for students majoring in composite materials to display their talents during the SAMPE China annual meeting, and at the same time encouraged students to open their minds, make full innovation, and design and produce their own lightweight and solid "perfect wings and bridges" to present to the industry

advanced composite materials are the most important structural materials supporting the cutting-edge scientific and technological fields of aviation, aerospace and national defense. They are strategic materials of a country and play an important role in the national economy and national defense construction. Because advanced composite materials have the characteristics of light weight, high specific strength, specific modulus, good ductility, corrosion resistance, heat insulation, sound insulation, shock absorption, high (low) temperature resistance, they can be used to process main load-bearing structures and secondary load-bearing structures, and their stiffness and strength properties are equivalent to or better than aluminum alloys. At the same time, because of its strong designability, molding by a variety of processes, and wide application, its continued clinical use can provide new challenges and opportunities for related industries to improve spinal function, which is an important direction for the application and research of engineering structures in the future
