The appraisal of scientific and technological achievements of Ronda Seiko High Performance Carbon Fiber Composite Card Roller Project passed smoothly

On July 9, 2021, entrusted by the China Textile Industry Federation, the China Textile Machinery Association organized the appraisal meeting for the scientific and technological achievements of the project "Advanced Manufacturing Technology and Application Development of High Performance Carbon Fiber Composite Carding Machine Roller" developed by Zibo Langda Composite Materials Co., Ltd. Jiang Shicheng, academician of Sinopec Yihua Co., Ltd., Chen Bo, former vice president of China FRP Industry Association, professor Wang Jun of Wuhan University of Technology, Fei Liya, former professor of China Textile Machinery Association, Tang Shuili, director of the Technology Development Center and senior engineer of Hengtian Heavy Industry Co., Ltd., were invited to the meeting. Jiang Shicheng served as the director of the appraisal committee. Gu Ping, President of China Textile Machinery Association, Hou Xi, Vice President, Huang Duanping, Deputy Director of the Management Committee of Zibo Hi tech Zone, Liu Xinen, Section Chief of the Science, Industry and Information Technology Bureau of the Hi tech Zone and other relevant leaders from the industry and regions attended the meeting.

During the meeting, experts of the appraisal committee, accompanied by Liu Peng, Chairman of the Board, and Zhang Puke, Vice President of Marketing, visited the production workshop of Landa, listened to the company's project reports, user use reports, and reports on testing and novelty search results, and reviewed the project appraisal data.

After inquiry and discussion, the appraisal committee fully affirmed the process technology, special processing machinery and products developed by our company in this project, and agreed that the overall technology of the project "Advanced manufacturing technology and application development of high performance carbon fiber composite carding machine roll" reached the international advanced level, agreed that the project passed the appraisal of scientific and technological achievements, and suggested strengthening industrial chain cooperation, continuing to increase research and innovation investment and industrialization promotion.

Project information:

The main products of this project are applied to non-woven fabric manufacturing equipment, which has been applied in many leading enterprises in the industry. Landa products have been installed and operated for many times, and the use functions meet the design indicators, and the performance reaches the international level of similar products; The product performance is stable, and no performance degradation is found after continuous operation; The product design is scientific and novel, realizing the perfect combination of material science, mechanics and mechanical energy; Compared with imported products with similar indicators, Landa products have obvious advantages in price and delivery time. From the user evaluation, the products of Rhonda can enter the purchase list of international famous enterprises such as Andritz, meeting its strict technical requirements, and some indicators even exceed the similar products abroad, which well verifies the international advanced level of the project.

In this project, 14 testing methods and technical standards were formulated, 2 authorized invention patents, 3 utility models and 1 software copyright were obtained. The density of carbon fiber roll involved in the project is only 1.6g/cm2, which is light in weight and small in inertia. It is more conducive to accurate control, and the controllable speed is significantly higher than that of traditional metal roll; The modulus of carbon fiber roller can be designed, which can reach 250GPa at most, with strong bearing capacity; The carbon fiber roller belongs to the interlayer flexible design, with good homogeneity, uniform stress, good stress resilience and no plastic deformation; Carbon fiber roller material is stable, with excellent fatigue resistance, and its service life is 8-10 years.
