It is a great pleasure and an honour to extend to you a warm invitation to attend the First International Conference on Defence Technology (1st ICDT) to be held during Oct. 21th-25th, 2018 at the Beijing Friendship Hotel, China.The 1st ICDT brings together many different aspects of defence technology, including energetic materials, materials behaviour and properties, advanced manufacturing techniques, impact mechanics and electromagnetic launch technologies.The conference offers papers on world leading research being conducted on pulsed power, hypervelocity, electromagnetic armour, prospective new energetic materials and new chemical propulsion concepts. It also covers practical problems related to quality control, aging, hazards, impact, disposal, and remediation of the energetic materials, in use today or in the near future, for space exploration or defence. There will be a special focus on manufacturing of composites, nano-materials and bio materials as well as applications of computer based manufacturing processes, machine vision and robotics. Also included will be materials for aerospace engineering, armour materials, advanced nanostructured materials, advanced ceramics and composites, and additive manufacturing. We hope the conference will provide you with the opportunity to make new contacts, discuss your excellent ideas, and infect everybody with your passion.Beijing has a rich and diverse cultural history extending back many centuries. Leading historical attractions within the city include the Forbidden City, Summer Palace, Temple of Heaven as well as more recent sites such as the Olympic Park.
