The International Conference on Composite Materials (ICCM) is the premier global forum for the exchange of knowledge, innovation, and collaboration in the field of composite materials. Since its inception in 1975, ICCM has brought together researchers, engineers, and industry leaders from around the world to advance the science and application of composites in diverse sectors including aerospace, automotive, marine, civil infrastructure, and energy. The 25th International Conference on Composite Materials (ICCM25) will be held in Singapore from 2 to 6 August 2027, marking a significant milestone for this flagship event. ICCM25 will showcase the latest advances in composite materials research, design, manufacturing, and sustainability, fostering dialogue across academia, industry, and government. With the strong all-of-nation support from Singapore’s leading institutions—including the National University of Singapore (NUS), Nanyang Technological University (NTU), the Singapore Institute of Technology (SIT), research institutes under A*STAR, DSO National Laboratories, and the Singapore Tourism Board—ICCM25 promises an exceptional scientific program and an engaging cultural experience. Participants can look forward to world-class plenary lectures, technical sessions, exhibitions, and networking events in one of the most vibrant and connected cities in Asia.
