The 18th ICCM was held on August 21-26, 2011 at the International Convention Center (ICC) in Jeju, Korea. The conference was hosted by the International Committee on Composite Materials and organized by The Korean Society for Composite Materials. It attracted more than 1600 scientific research jobs in 47 composite materials related industries from 47 countries. Graduates and graduates participated in, refreshing the record of previous attendance. Professor Du Shanyi, Vice Chairman of the Chinese Society for Composite Materials and Vice Chairman of this conference, led more than 100 representatives from Chinese universities, institutes, and experts and business representatives to participate in this conference. Our country has gradually caught up in the field of composite materials and has become a very important part of the international composite materials industry.
Composite materials and related industries are an important part of the world's economic industry chain. According to JEC CEO F. According to data provided by Ms. Mutel, the market for composite materials related industries worldwide has reached 85 billion U.S. dollars. Market analysis data predict that after the economic crisis from 2007 to 2009, the world economy will gradually recover at a rate of 5% to 6%. The composite materials industry as an emerging industry has become the focus of development in many countries and will have an important impact on the further recovery of the world economy. . Therefore, the International Composites Conference not only attracted a large number of university and research institute researchers, but also attracted many people in the industry.
During the five-day conference, a conference Scala report (a report named by well-known composite material expert Scala), 18 theme reports, more than 900 oral reports, and more than 300 posters were arranged. The report covers traditional resin matrix composites, metal matrix composites, ceramic matrix composites, and carbon/carbon materials, as well as new composite materials such as nanocomposites, biocomposites, etc. The application direction is aerospace. , automotive, construction, and wind energy. This conference provided a platform for mutual exchange and discussion for composite materials researchers working in different research fields around the world. Many high-level reports not only introduced the new technologies and new developments of composite materials, but also predicted the development of composite materials industry.
The new trend-functionalized composite materials for structural materials have always been considered as structural materials, but researchers are paying more and more attention to the development of their functions. Many of the reports attended were related to the function of composite materials. To give more functionality to composite materials has become a new hot topic in the research of composite materials in the world. Professor Thomas Hahn from the University of California, Los Angeles made a Scala report entitled "Composite Materials: From Structural to Multifunctional". Prof. Hahn said that in the past 30 years, composite materials have mainly undergone material development - cost reduction - practical application research. With the wide application of composite materials in the fields of aviation, wind energy, automobiles, etc., people no longer satisfy that composite materials only serve as structural materials and gradually develop their various functions.
Professor Hahn mainly spoke about the functionalization of composites by adding nanoparticles or developing new functional resins. The improved composite material has special properties in electricity, heat, magnetism, chemistry, biology, optics, etc. In the future, it can be applied to the fields of composite structure health detection, self-healing, energy storage and electromagnetic fields.
For example, Professor Hahn's team used aluminum hydroxy groups present on the surface of nanoparticles to modify the surface of alumina nanoparticles with a bifunctional coupling agent. The coupling agent can be further polymerized with vinyl ester resin and modified by this method. Resin strength and modulus are both improved, and the increase is related to the nanoparticle content.
New Ideas - The new unplanned and unsymmetrical layering design of the ply design can greatly reduce the difficulty of ply design, reduce the weight of the structure, and thus reduce costs, but unbalanced and asymmetric plies are rarely used. This is because during the curing process, unbalanced, asymmetrical laminates have large internal stresses and are prone to deformation. Prof. Stephen Tsai from Stanford University mainly introduced an unbalanced and asymmetric layering method that can reduce the weight of the structure and save costs.
In the general ply design, the commonly used ply has four different angles of 0, ±45°, and 90°. Prof. Tsai suggested using the [0/25] double-ply structure instead of the above-mentioned commonly used ply, and the thickness of each double ply is only 1/2 of the thickness of the commonly used ply. Through the calculation of the torsion-torsion coupling matrix, the [0/25] double-ply structure can effectively reduce the internal stress, thus achieving unbalanced, asymmetric lamination design. Prof. Tsai also developed non-crimp fabric (Non Crimp Fabric) to achieve [0/25] double-ply structure. Chomarat, a company partnering with Professor Tsai, opened a booth at the venue for product demonstrations.
