High-Performance Composite Materials

MATECH FAST-DENSIFIED SiC COMPOSITES FOR 2700F CMCs Higher temperature performance of commercial and military Turbine Engines and Rotational Detonation Engines (RDEs) is essential for Next Generation propulsion systems. Applying Field Assisted Sintering Technology (FAST) to CMC manufacturing enables higher temperature capability and greater thermodynamic efficiency. This ceramic matrix composite (CMC) technology goes beyond today's state of the art in CMC manufacturing. The unprecedented properties afforded by FAST SiC matrix CMCs opens the door to performance gains for propulsion technologies in both commercial and defense aviation. Hypersonic propulsion technologies could also benefit.  The technology is covered by U. S. Patents 10,464,849 and 10,774,007. Patent 10,774,007 is a "composition of matter" patent, which is the hardest to obtain of all patent types. This technology is available for licenses. For turbine engine applications, FAST SiC/SiC CMCs can be densified in 10 minutes to near-net-shape. This results in highly dense SiC/SiC CMCs never attainable previously with near 0% porosity. High strength capabilities and excellent CMC fracture behavior (fiber “pull-out”) were demonstrated. Dramatic savings in operating costs and improved thermodynamic efficiency can be achieved. This technology also enables up to 2700F CMCs in turbine engines. FAST C/SiC CMCs are a candidate for Rotational Detonation Engines (RDEs). For RDEs, highly dense FAST C/SiC CMCs with near 0% porosity result. Hypersonic engines seek to benefit from RDE technology by reducing overall engine mass and increasing efficiency by 30-40 percent. Rotational detonation engines would provide for greater engine power density as well as fuel efficiency gains for greater range. Potential applications of the RDE engine technology extend to hypersonic weapons systems and, ultimately, aviation. Other demanding applications for FAST SiC CMCs abound. These include missile propulsion, leading edges, nose-tips, ceramic armor, high temperature radomes, ballistic protection solutions, heat exchangers, heat shields, exhaust nozzles and combustors, tough ceramic composite cutting tools, wear resistant parts, and semiconductor processing tooling. FAST hardware is scale-able to large components. Due to its brief requirement for energy (circa 10 minutes to fully densify a part) the costs are lower per part. Because throughput is high in production, FAST densification of CMCs is affordable. This is especially true for applications that demand the unique and otherwise unobtainable properties. FAST SiC/SiC and C/SiC CMCs are a game changing manufacturing technology for high performance propulsion systems in aerospace and defense. A wide range of additional applications can benefit from this technology.

“The research uses a nanocomposite material comprising inorganic, hexagonal boron nitride (hBN) fillers embedded in a thermoplastic polymer. By carefully combining additives, surface treatments and thermal post-processing, the team created a crystalline polymer structure that bridges the highly conductive fillers, significantly enhancing thermal conductivity… The nanocomposite is first formed into continuous filament, which can then be fed into a desktop 3D printer to create complex structures such as heat sinks, thermal spreaders, mounting plates or panel covers. The 3D printing process further aligns the fillers, boosting the material’s performance.” #additivemanufacturing #3dprinting #army #usmilitary #research #materials #polymer #heat #thermalresearch #engineering
