Composite materials consist of two parts of reinforcing fibers surroundedby a resin matrix consisting of two categories of thermoset andthermoplastic, and the method of making them is pultrusion.Due to its low density and light weightiness, good mechanical propertiesin different directions and durability and high corrosion resistance arewidely used in various industries.The popularity of recycling them has increased due to environmentalprotection and the production of functional composites from materialsrecovered from their recycling.
