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).
