FIELD: transport.
SUBSTANCE: invention relates to noise absorbing panels, namely to those used in noise absorbing appliances incorporated with aircraft power plants etc. Proposed method comprises fabricating tubular elements by winding prepreg onto mandrel and laying layers on skin with heating every layer there before. Axes of first layer mandrels are parallel to those of second layer mandrels. Tape coils on mandrels form a grid. To produce holes, tapes are laid on panel outer layer perpendicular to tapes wound on mandrels.
EFFECT: reduced weight.
