Fuzzy Fibers Make Better Rockets

Apr-01-17 Fuzzy fibers able to withstand extreme heat could help usher in the next generation of rocket engines.

Silicon carbide fibers are currently used to strengthen the ceramic composites in rockets, but they can crack when exposed to oxygen.

To offer a stronger solution, the team from Rice University added to the fibers by embedding silicon carbide nanotubes and nanowires onto their surface. This technique left some of the fibers exposed, causing them to curl and interlock, much like Velcro. This in turn stregthens the composite, while also sealing it to help prevent degradation by oxygen.
