http://economiacircularverde.com/que-es-la-economia-circular/ What is the difference between synthetic materials and composite materials?
Synthetic material: also known as man-made material, is a material that artificially processes different substances by chemical methods or polymerization.
Typical products are plastics, synthetic chemicals, resins, and the like.
Composite material: A material with new properties formed by macroscopic (microscopic) physical or chemical methods from two or more materials of different nature.
Various materials complement each other in performance, resulting in synergistic effects, so that the composite material’s overall performance is superior to the original composition material to meet various requirements. The matrix material of the composite material is divided into two major categories of metal and non-metal. Aluminum, magnesium, copper, titanium and alloys thereof are commonly used in metal substrates. Non-metal substrates mainly include synthetic resins, rubber, ceramics, graphite, carbon, and the like. Reinforcing materials mainly include glass fiber, carbon fiber, boron fiber, aramid fiber, silicon carbide fiber, asbestos fiber, whisker, wire and hard fine particles.
