The unsaturated polyester resins are among the most commonly used resins in composite materials. UP resins are a colourless to slightly yellow solution of unsaturated polyester in a reactive solvent, usually styrene. At room temperature or by supply of heat, they are cured, whereby a heat reaction is released.
