With materials like EGlass, SGlass and Kevlar to contend with, is carbon fiber truly the king of composites? Carbon fiber has the greatest stiffness to weight characteristics of most materials, but is it the right choice for building a supercar on a budget? That is the question we set out to answer in this video. We investigate the material properties that often get lumped together in being called "strength," to understand what is best and what the best might cost.
