Abstract
[Abstract] Vacuum assisted resin transfer molding (VaRTM) method is one of the candidates to achieve low cost aircraft structure. A development of 6 m span VaRTM wing box project is conducted to demonstrate VaRTM technology and to make clear the certification procedure of VaRTM by Japan Aerospace Exploration Agency (JAXA). The project result will eventually support the policy and guidance procedures of Japan Civil Aviation Bureau (JCAB), and also a certification procedure of aircraft companies in Japan. This 6 m VaRTM made wing box demonstrator is assumed a 30 passenger aircraft and a static test of this wing box is planed in fiscal year of 2007. A 2 m wingspan specimen was made as an experimental production which contains every technical component to be solved before manufacture of 6 m wing box specimen. Technical expertise and the remaining issues were obtained from this 2 m specimen.
