Enhanced All-Composite NGV Fuel Container Design and Qualification 2000-01-3474
Lincoln Composites has conducted research to reduce cost and weight of all-composite NGV fuel containers. This research was conducted in cooperation with Battelle and others under GRI funding. Heavy tow carbon fiber was investigated as a means of reducing material cost. Advantex® glass fiber was evaluated as a replacement for conventional E-glass. Changes to the dome contour reduced fiber stresses due to bending. Other design and manufacturing issues were addressed. The design was finalized and passed all required NGV2 qualification tests, which were conducted by Powertech Labs. The overall program goals for cost and weight were achieved.
