The high-density polyurethane foam mandrel surface used in the production of the invention to be cost- effective is made conductive by metalizing by means of Sn sensitization and Pd activation, firstly electroless and then electroless nickel or nickel alloy coated with electroform method. The composite laying mold was obtained by removing the coating from the mandrel. APPLICATION FIELDS TR202010823 In the state of the art, while the mandrel material to be used for complex and large-sized parts is preferred, stainless steel is used. This causes high mold production costs. The materials that used as molds cause expansion of molds by not being able to withstand high temperatures and pressures in autoclaves during the production of composite parts. This causes of production of distorted shape parts.
