  "textContent": "The acoustically resistant panel is made by winding a strip of an acoustically resistant material (13) onto a mould (M) to give it the required shape, following it with a structural layer, a cellular core and a total reflection layer before withdrawing the mould. The acoustically resistant layer has sections (P'1, P'2, P'3) of varying porosity adapted locally to the sound wave impact point characteristics, the correlation between the characteristics and the impact zone being predetermined with the aid of conventional impact technology applied to an identical test panel. The wound strip is made from a fabric or metal mesh and carbon or glass fibres pre-impregnated with a thermoplastic or thermo-setting resin.",
