A composite structure comprises a first substrate, a film, and a second substrate. The film comprises a first outer layer, a second outer layer, and an intermediate layer between the first and second outer layers. The first substrate comprises one or more polymers selected from polyurethane and polyester and is adhered to the first outer layer of the film. The second substrate is adhered to the second outer layer of the film. The first outer layer of the film comprises ionomer. The second outer layer of the film comprises one or more polymers selected from a) ionomer, b) polyamide having a melting point of at most about 200° C., c) amorphous polyamide, and d) polyester. The intermediate layer comprises one or more polyamides. The composite structure may be, for example, an automotive headliner assembly.
