Embedded-Wire CVD (EWCVD) was developed by FFF as an innovative approach to produce high purity, high density CMC structures and composites. This technique builds upon our previous work with Laser-CVD (LCVD) and composite samples.
An important application of EWCVD is joining (welding) of ceramic and ceramic-based composite components together. FFF has demonstrated homogeneous joining of SiC fiber-reinforced SiC matrix composites from EWCVD.
SiC is currently a candidate for nuclear fuel cladding as either a monolith, a SiC fiber-reinforced SiC matrix (SiC/SiC) composite, or a hybrid of metal and SiC/SiC composite, utilizing our LCVD SiC fibers. EWCVD is also being deployed to address this issue and form a fully dense, hermetic end cap seal. Further extensions of the EWCVD technology to SiC-SiC composites are also being explored.
