Abstract
The invention provides a method for making a composite (10) including two skins (14) of composite material bonded on either side of a core (12) having the form of a honeycomb type panel, including a step of firing the skins (14) onto the core (12) to simultaneously carry out hardening of the skins (14) and bonding of the skins (14) with the core (12), characterised in that it consists in placing a rigidifying layer (22) between the core (12) and at least one skin (14).
Claims10
A method for making a composite (10) including two skins (14) of composite material bonded on either side of a core (12) having the form of a honeycomb type panel including cells (16) perpendicular to the main plane of the panel,
- the method including a step of superimposing the skins (14) and the core (12) onto a mould (18) and a step of firing the skins (14) on the core (12) to simultaneously carry out hardening of the skins (14) and bonding of the skins (14) with the core (12),
- characterised in that it consists in placing a rigidifying layer (22) between the core (12) and at least one skin (14) during the step of superimposing the skins (14) and the core (12), said rigidifying layer (12) being made so as to distribute pressure strains between said at least one associated skin (14) and the core (12).
