Investigation of Joints for a Modular Composite Bridge

02 August 2001


The U.S. Army Tank-automotive and Armaments Command (TACOM) is planning to award a research and development contract on a sole-source basis to Seemann Composite Inc. for the investigation of joints for a modular composite bridge.

This effort is a follow-on procurement to Phase II of the Composite Army Bridge (CAB) program that was awarded by DARPA in 1996. SCI is the only source who has successfully demonstrated the ability to develop incremental technology leading to a full-scale composite army bridge capable of sustaining heavy vehicles using the Seemann Composite Resin Infusion Molding Process (SCRIMP). The focus of this Cost-Plus-Fixed-Fee (CPFF) contract is to advance the CAB technology through the development of joints/connections in the bridge components.

This effort will include a base award with an option. The base effort will include the investigation of various joints that can meet a variety of requirements for sectionalized composite military bridging applications for rapidly employed, medium weight traffic. This base phase will involve feasibility and trade-off analyses to determine optimum joint designs and manufacturing approaches, manufacturing and testing coupons and sub-scale and full-scale samples. The option will include the design, manufacture, delivery, and testing of up to two full scale demonstrators using selected joints/connections.
