TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
The intent of the proposed effort is to investigate the detailed composite overwrapped pressure vessel (COPV) performance characteristics after being subject to irradiation, hypervelocity micro-meteor impact, and cryogenic environments. This will result in a safer, more reliable design for high performance COPVs.

This intent will be achieved via empirical characterization of composite raw materials subsequent to exposure of the aforementioned environments. Phase I of this effort (NASA contract #NNM06AA56C) demonstrated a significant reduction in structural performance following exposure to various combinations of the aforementioned environments. This reduction in structural performance would seriously compromise the structural performance of any composite structure to be utilized in deep space applications. The data proposed in this effort would be extremely useful to NASA in what might be used in the upcoming CEV and

The aerospace and the commercial communities have shown significant interest in using filament wound COPVs for cryogenic applications. In addition there is serious consideration for using COPVs in deep space exploration which would sustain significant radiation exposure and possible impact damage. Constituent raw materials and existing COPV designs have not been characterized for the coupled effects of these applications and as such the safety margins for these applications are undefined. Therefore, the reliability of such usage is unknown.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
NASA applications for the research proposed herein would include the following:

? Cost efficient cryogenic storage vessels. These vessels could be utilized as both earth-based and space-based cryogenic storage vessels.

? Habitat structures. The research proposed herein is applicable to space-based habitat and other structures manufactured with fiber-reinforced composite material.

? Volumetric efficient cryogenic storage vessels. HEI's high pressure storage systems are highly volumetric efficient.

? Reliable, long system life cryogenic storage. HEI have successfully designed, manufactured, and cycle tested COPVs with up to 20,000 cycles.

? Space-based cryogenic COPVs. It is probable that COPVs utilized in space will
experience impact damage due to micrometeoroids and other space debris and it is certain that the COPVs will experience radiation damage. The research proposed herein will assist the COPV designer by identifying the coupled effects of hypervelocity impact damage, cryogenic temperatures, and irradiation ? thus developing mechanical property allowables for the designer.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Non-NASA commercial applications for the research proposed would include the following:

? LH2 fuel cell. HEI is currently executing a contract for LH2 storage for a vehicle application. This research will aid the mobile fuel cell industry safety and reliability.

? Vehicular CNG storage. The research proposed herein will aid the safety and reliability of the CNG vehicle market.

? Marine-transport of propane. The research proposed herein will develop knowledge and data applicable to transporting propane in tanker ships.

? Environmentally-friendly earth-based cryogenic fluid storage. Composite structures do not react to environmental corrosion as do the typical cost efficient metals such as steel.

? Safer earth-based cryogenic fluid storage. Due to the high strength of composite materials, little raw material is required to perform draconian structural feats when compared to typical cost efficient metals. Therefore, the manufacturing and movement of large COPVs is much less expensive and much safer.

NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.
