Composite Pressure Vessel Capabilities

Composite Pressure Vessel

White Sands Test Facility (WSTF) offers leading expertise in the testing, nondestructive evaluation (NDE), and analysis of composite material structures. WSTF performs stress rupture tests, damage tolerance, hydraulic and pneumatic burst tests, and environmental effects studies on composite pressure vessels. WSTF offers material compatibility testing and analysis, structural health data analysis and Finite Element Analysis (FEA) modeling, stress rupture life and damage control planning, and high pressure blast and fragmentation analysis.

Publications

Composite Conference 2012 was co-hosted by White Sands Test Facility in August 2012. The conference focused on composite pressurized structures and vessels, bringing together the international composite community to discuss advances in composite performance, durability, and safety. The proceedings from Composite Conference 2012 have been compiled into an e-book for download.
