The oil embargo of 1973 forced government and businesses to innovate their way out of the crisis. For GE, that meant focusing on multi-layered high-tech called composites, and teaming up with NASA to develop an experimental, energy-efficient engine called the GE36. While the GE36 never became a commercial engine, GE continues to use carbon fiber composite blades for engines including the GE90 and the GEnx.
