A multi-layered structure with improved stability and insulation is disclosed. Methods for making the multi-layered structure are also disclosed. The structure comprises layers of foam and layers of solid material which are sprayed onto each other via an industrial robot having spray nozzles. The layers of foam are sprayed onto a supporting structure of a building, and the process of spraying is such that each consecutively sprayed layer is initiated after only a short lag in time from the initiation of the previous layer. The structure comprises at least two layers (preferably at least three layers), each layer having different mechanical properties. The layers may further be reinforced with reinforcing fibers and/or fiber fragments. An additional layer of fibrous material may comprise outer and/or inner layers of the structure. The disclosed structure is built faster and has significantly higher load-bearing and insulative capacities than the state of the art.

In some examples, the disclosure describes a method including densifying a layer of carbon fibers by at least one of depositing a resin on the layer of carbon fibers via a print head of a three-dimensional printing system or applying CVD on the layer of carbon fibers via the print head; and forming at least one additional layer of densified carbon fibers on the densified layer of carbon fibers, wherein forming the at least one additional layer of densified carbon fibers comprises, for each respective layer of the at least one additional layer, adding an additional layer of carbon fibers on the densified layer of carbon fibers, and densifying the additional layer of carbon fibers by at least one of depositing the resin on the additional layer of carbon fibers or applying CVD on the additional layer of carbon fibers. In some examples, the example method may be used to form a densified carbon-carbon composite component, such as, e.g., a densified carbon-carbon composite brake disc.
