• The Transition Reliable Unitized Structure (TRUST) effort aims to develop data informatics approaches for quantification of the composite bonding process to enable adhesives alone to join composite structures. State-of-the-art techniques rely on mechanical fasteners in addition to adhesives. TRUST seeks to eliminate the reliance on these fasteners, thereby enabling bonded composites to take advantage of adhesive joining to streamline assembly and lighten the weight of the structures.

The Open Manufacturing program has established two Manufacturing Demonstration Facilities (MDFs)—one at Penn State focused on additive manufacturing and the other at the Army Research Laboratory focused on bonded composites. The goal of these MDFs is to establish permanent reference repositories that endure long after the Open Manufacturing program concludes, where individuals can access various contributed approaches and processes models. The facilities also serve as testing centers to demonstrate applications of the technology being developed for the Department of Defense, its industrial base, and other agencies, and as a catalyst to accelerate adoption of the technology.

“Historically, U.S. military advantages were supplied by breakthroughs in materials and manufacturing,” Maher said. “More recently, the risks that come along with new manufacturing have caused a lack of confidence that has stifled adoption. Through the Open Manufacturing program, DARPA is empowering the advanced manufacturing community by providing the knowledge, control, and confidence to use new technology.”
