The Composite-Concrete Beam technology uses hybrid thermoplastics in which the beam is outfitted with welded shear studs. This research was commissioned by the Engineering Research and Development (ERDC) of the U.S. Army Corps of Engineers for the development of a stiffened panel system for use in load-bearing hybrid composite-concrete structures.


  • A literature review of thermoplastics and their variety of advantages in structural applications including recyclability, corrosion resistance, amenability to rapid manufacturing, impact resistance, and high strength-to-weight ratio.
  • Material characterization of two thermoplastic materials (Elium acrylic and polyethylene terephthalate glycol (PETg) prepreg tapes) to build a basis for materials selection for component-level specimens. Both materials are used with E-glass reinforcing fibers. 


  • The process of using hybrid composite-concrete structures can be extended to other applications such as bridge decking, retaining walls, and columns
