Reducing Complexity: DARPA Seeks New Composite Material and Process for Manufacturing Small Parts

New combination feedstocks could revoke a cost and prolongation time of small, lightweight combination collection — augmenting troops complement opening and compressing apparatus growth and phony cycles



The prolongation routine for invulnerability systems—from aircraft to vehicles to ships—is intensely formidable and fragmented, mostly perfectionist singular materials and processes, formidable acceptance mandate and specifications, and specialized collection and equipment. The roughly unavoidable result: extensive prolongation timelines and high costs. The make of different tiny collection for troops systems could be done simpler, faster, and reduction dear with a growth of a tailorable combination feedstock element and a singular tailorable combining method.

To grasp this goal, DARPA has launched a Tailorable Feedstock and Forming (TFF) program, that aims to revoke a time and cost burdens compared with stream prolongation pattern and growth cycles for invulnerability platforms. TFF aims to cut a turnaround time for partial modifications and redesigns by as most as 50 percent. A proposers day is scheduled for Sept. 15, 2015.

Composite materials are intensely clever and lightweight, though programmed systems for producing combination collection are now cost-effective customarily for collection weighing 20 pounds or more. Parts weighing reduction than 20 pounds are customarily done regulating metals, such as aluminum, that cost reduction than composites though are some-more dense, adding weight to a system.

“Eighty percent of tiny collection are done of steel due to a restricted phony cost of combination collection underneath 20 pounds,” pronounced Mick Maher, module manager in DARPA’s Defense Sciences Office. “Although steel collection are cheaper to make, their additional weight leads to sub-optimal opening of a system. Through TFF, we aim to rise a versatile combination element and an variable combining routine to concede affordable phony of mixed partial configurations from a same work cell.”

TFF has dual categorical concentration areas—how to make aerospace combination materials some-more affordable and how to routine this new element into useable product form, Maher said. In stream combination manufacturing, building a collection to routine materials into products takes a poignant volume of time. Any pattern changes in a height need redesign of a collection ensuing in poignant cost and report delays. “Tooling processes can take 6 to 12 months per pattern cycle, significantly pulling out a timeline for production,” Maher said. “By building stretchable combining solutions to concede for mixed collection from one work cell, we trust we can digest a prolongation and prolongation cycle for parts—which typically includes an initial pattern and dual re-design periods—down to 3 years, from today’s normal of about 6 years.”

The TFF module is seeking a tailorable short-fiber combination feedstock that is stampable and moldable and yields aerospace-grade properties. TFF also seeks technologies to emanate a tailorable combining work dungeon able of prolongation mixed partial configurations with minimal reconfiguration costs and permitting fast phony cycle time.

“If we’re successful, this module should revoke a weight of troops systems by creation combination collection as affordable as metal, discharge a extensive and dear re-tooling burden, and open new pattern space for tiny combination parts,” Maher said.
