METHOD OF APPLYING AN INTERMEDIATE MATERIAL MAKING IT POSSIBLE TO ENSURE THE COHESION THEREOF, METHOD OF FORMING A STACK INTENDED FOR THE MANUFACTURE OF COMPOSITE COMPONENTS AND INTERMEDIATE MATERIAL

摘要

The present invention relates to a method for continuously applying to an application surface an intermediate material consisting of a unidirectional layer of reinforcing fibres which is associated on at least one of its sides with a layer of thermoplastic and/or thermosetting material which represents no more than 10% of the total weight of the intermediate material, in which method: the intermediate material has, prior to being applied, undergone an operation involving the point-wise application of through-loads accompanied by heating causing a penetration of the thermoplastic and/or thermosetting material and creating connecting bridges within the thickness of the unidirectional layer of reinforcing fibres, the intermediate material is applied continuously with the simultaneous application of tension and pressure so as to apply to the application surface a side of the intermediate material that is in the process of being applied that corresponds to a layer of thermoplastic and/or thermosetting material and activating said layer of thermoplastic and/or thermosetting material during the application thereof so as to create a bond between the applied intermediate material and the application surface; to a method of forming a stack for creating composite components that implement said method and to various uses thereof.
