Ultra-light high-performance sound-absorbing material with carbon fiber and down feather laminated structure

The invention discloses an ultra-light high-performance sound-absorbing material with a carbon fiber and down feather laminated structure. The ultra-light high-performance sound-absorbing material isformed by laminating a plurality of carbon fiber layers and down feather sound-absorbing layers; wherein rubber pads distributed in a net shape are arranged on the inner side of the carbon fiber layerand bonded with the down feather sound absorption layer, the cross section of each rubber pad is in an I shape, the two end faces of each rubber pad are used for being bonded with the carbon fiber layer and the down feather sound absorption layer through adhesives, and gaps of the rubber pads are filled with down feathers with the filling density being 30-50%. The down feather sound absorption layer is formed by transversely and longitudinally interweaving composite fiber hollow pipeline groups filled with down feather, wherein each composite fiber hollow pipeline group is composed of a certain number of composite fib
