Ambient Processing for In-Situ Selective Reinforcement (ISSR) of Near Net Shape Structures

Status: Completed

Start Date: 2017-10-01

End Date: 2018-09-30

Description: Use AMPB's laboratory-scale rolling mill to simulate the dynamic conditions associated with metallic structure forming and fabrication methods. Use aerospace aluminum alloys and commercially-available aluminum metal matrix composite (MMC) for reinforcement. Assess aluminum flow behavior and the strain fields within the MMC and their effects on the reinforcing fibers. Flow aluminum plate material into grooved die with preplaced MMC to form and reinforce stiffeners at selected processing temperatures. Evaluate bond microstructures and mechanical properties.
Benefits: The aeronautics mission directorate is interested in this work and has provided funding for technology maturation.
