In the wake of the loss of the OceanGate Titan submersible, there was much discussion and speculation about the materials used to manufacture the vehicle. Many pointed to the use of carbon-fiber as a potential source of failure, yet there has been a good deal of success in the use of the material for undersea applications including pressure vessels and unmanned submersibles. 

In this episode of CW Talks, we sit down with two representatives from Composite Energy Technologies Inc., a Bristol, RI based company that manufactures a wide range of composite structures from racing sailboats to architectural designs to theme park ride vehicles to defense applications including deep-sea submersibles.  Chase Hogoboom, president and TJ Perrotti, senior Naval architect and chief design engineer discuss their experience working with the U.S. Navy on submersible designs and the rigorous testing that goes into the use of carbon fiber for undersea applications. 

In episode 40 of CW Talks: The Composites Podcast, Jeff Sloan, editor-in-chief of CompositesWorld sits down with Sarah Cox, Materials Engineer at NASA. Sarah has worked for NASA for more than 18 years and has experience applying advanced materials to space structures. Jeff talks to Sarah about her education, how she came to NASA and how she helped guide composites use there.
