      <title>CAN COMPOSITE MATERIALS COMPETE IN VEHICLE TORSION MEMBERS?</title>
      <link>https://trid.trb.org/View/161582</link>
      <description><![CDATA[Automotive components made from advanced composite materials result in significant weight savings over steel and aluminum.  One of the problem areas is the application involving torsion members.  Specifically those applications where torsional shear strength, shear fatigue, or shear strain are limiting factors.  In automotive components this includes torsion bars, coil springs, and the shorter drive shafts.  In this paper the strain limitations of advanced composites are compared to other materials and this effect demonstrated in the design of a torsion bar.  A parametric analysis is shown which directly indicates when, for a particular application, advanced composite materials can or cannot be utilized.]]></description>
