3. Thermal processes
Composite materials, like all materials with an organic component (in this case the polymer matrix), have a calorific value that enables them to be used as a source of energy.
For example, thermosetting resins (unsaturated polyester, vinylester, phenolic, epoxy) have an average calorific value of 30,000 kJ/kg.
As the fibers and fillers most commonly used (glass, flame retardants, etc.) are incombustible, the calorific value of a glass/resin composite generally depends on the polymer matrix content (linear variation from 30,000 kJ/kg for 100% polymer to 0 for 0% polymer) [1]. Several solutions for the thermal treatment of waste and energy recovery, including some with partial material recovery of the residues generated, can therefore be envisaged.
