A load-bearing composite material structure (2) includes a first ply (10) of fiber reinforced composite material, and an integral blanket (20) for thermal and flame protection. Blanket (20) includes an outer flame resistant face sheet (28), an intermediate layer of insulation fill (26), and an inner face sheet (22). Sheet (22) is formed by a second ply of fiber reinforced composite material. Preferably, a thin film (24) is provided between ply (22) and fill (26) to prevent absorption of matrix material into fill (26). The layers (22, 24, 26, 28) of blanket (20) are stitched together with flame resistant thread (30). Plies (10, 22) are cured together to bond them together and integrate blanket (20) into structure (2).

A load-bearing composite material structure with integral thermal and flame protection, said structure comprising: a first ply of composite material, and an integral blanket bonded to said first ply; said first ply including a thermosetting matrix material, and a fibrous material reinforcing the matrix material; and said integral blanket including: an inner face sheet formed by a second ply of composite material, said second ply including a thermosetting matrix material reinforced by a fibrous material; an outer face sheet that is resistant to flame penetration; a layer of insulation fill between said inner and outer face sheets of sufficient thickness and sufficiently low thermal conductivity to provide a predetermined degree of thermal insulation; and high temperature resistant thread stitched through the layers of the blanket to sew such layers together; said first and second plies being cured together, after the layers of the blanket are stitched together, to bond said plies together to in turn bond the blanket to said first ply and integrate the blanket into the structure.
