Project Objective

To The focus of the proposed research is to develop composite structures from recovered roofing scrap. The use of recycled materials in composites provides the potential for large cost savings. This project will also impact the community by diverting thousands of tons of shingles and other waste materials from the landfills.

Project Abstract

Composite panels will be manufactured from ground scrap shingles. Pultruded composite tubes will be used as the outer skin and the core will be composed of ground-up shingles. Pultrusion is an automated and continuous process to manufacture polymer composite structural shapes. Experimental tests will be conducted and applications to sound barrier system will be investigated.

Task Description

  1. Grinding of the scrap shingles.
  2. Composite manufacturing.
  3. Experimental load-tests.
