FIELD: building.SUBSTANCE: method is carried out by installing the mounting plate on a structure made of composite material. Wherein the structure is obtained by the method of injecting resin under vacuum. Moreover, the method involves placing the fiber preform in a closed mould, injecting thermosetting resin into the mould and polymerizing the resin prior to cooling. The method consists of installing the metal mounting plate on the mould wall before inserting the fiber preform into place. Wherein the mounting plate comes into contact with one surface of the fiber preform, while it is inserted into place in the mould, and the resin is deposited between the mounting plate and the fiber preform, while it is injected into the mould.EFFECT: increasing the equipment mounting strength of the structure of a composite material.10 cl, 4 dwg
