Recovery of composite resins

Definition

  • Solid product comprising at least two separate constituents joined by a bonding material.

  • The association confers on the set of properties that none of the components taken separately possess.

  • The assembled materials can be wood, plant fibers, plastic, metal...

  • Glass and carbon fibers are CMOs (organic matrix composites), used for:

    • Boat hulls

    • wind turbine blades,

    • etc
