While at UCSB, I built a bridge from carbon fiber and aluminum with the help of three other students. We took first place in the SAMPE lightweight bridge-building competition held at Long Beach in 2005. The bridge spanned 24", weighed 2.62 lbs, and supported 8905 lbs at mid-span before failure. It was built from pre-made carbon fiber tubes for compression loads, which we joined together with aluminum end brackets. We added unidirectional carbon fiber ribbons to handle tension loads. The fibers were pre-impregnated with epoxy resin, and kept in a freezer until they were laid in place and cured at high temperature and pressure.
