Carbon Flight (Sacramento, CA, US) was at the show for the first time, and in fact, launched its company a few days before CAMX. It has developed a unique way to create hollow carbon fiber parts, using a wax strand overwrapped with dry carbon fabric in a helical manner. The wax-filled carbon is filament wound on a mandrel, then infused and cured at room temperature. After part cure, the part is heated, which melts the wax; part design allows it to flow out, leaving engineered cavities with strong walls. Company president Lauren Abarca says that the helical design of the carbon around the cavities provides better lateral compression properties, and the company is exploring applications where cavities will offer light weight plus added functionality.
