The linerless composite cryogenic tank technology that is proposed herein can provide enabling capabilities for several near-term and longer-term NASA mission goals including those intended for future heavy launch vehicles, planetary and asteroid decent and accent vehicles, in-orbit spacecraft re-fueling as well as for long term storage in deep space on one planetary surfaces such as the moon. Indeed, the development of lightweight, linerless composite tanks for these applications will help to reduce mass, which is a critical need for these systems. Lightweight composite tanks can also be used for storage of hydrogen in fuel cell driven high altitude long duration aircraft as well as other unmanned air vehicles with varying mission objectives. In addition to storage tanks, the manufacturing technology being developed here can be used for composite cryogenic piping and other aircraft parts. The linerless composite cryogenic tank technology that is proposed can provide enabling capabilities for a variety of other government, industrial, and commercial uses. For example, liquid hydrogen tanks can store more fuel in a given volume (i.e. higher energy density) when compared to their compressed gas counterparts making composite liquid hydrogen tanks attractive to automotive manufacturers such as BMW. Additionally, the out-of-autoclave prepreg materials developed under this program would be highly valued for larger manufacturing efforts that use prepreg process such as for wind and tidal turbine blades and large aircraft structures.
