    The material, CURV®, Manufactured by Propex, is light, stiff, with a high

    Young’s modulus and high damping, not hydroscopic, and provides high

    temperature tolerance. CURV is relatively inexpensive, at least when

    compared to carbon fiber or Kevlar.

     

    What is it made of? In a nutshell, pure polypropylene (PP) is extruded, drawn

    into tapes, woven, and heat-treated to produce a self-reinforced PP composite.

     In this unique patented process, the surface of the tapes is selectively melted

    to bond the fabric together, providing a single polymer composite.

     

    The drawing process provides higher stiffness during drawing by orienting

    the polymer and, as the surface facings are melted and re-crystallized to form

     the matrix, an ultra-stiff and smooth skin sheet is produced. The resulting sheet

    material properties are enhanced through this molecular orientation rather than

    mineral loading.
