Metal-matrix composites and IPM: A modeling perspective

The intelligent processing of materials: An overview and case study

“…23 The result is typically a 200 µm thick monotape containing parallel, evenly spaced 140 µm SCS-6 silicon carbide fibers in a porous matrix ( Figure 2). The monotapes are laid-up to create a preform with the desired fiber architecture and then either hot isostatically pressed or vacuum hot pressed to near-net shape.…”

“…They include foil-fiber-foil, 51 vapor-phase fiber coating, 52-54 powder cloth, 55 and molten-droplet spray deposition. 23 Each reduces or even eliminates liquid matrix-fiber contact, but all require additional lay-up and consolidation process steps to achieve a near-netshape composite.…”

“…1,22,23 As a feedback control methodology, it is predicated upon the development of microstructure sensors. These are new sensor technologies originally developed by the nondestructive evaluation community, with the capability to more directly sense the product being formed and allow inferences of its quality-defining attributes.…”
