A composite structure (1) has first and second fibre reinforced composite layers (2, 3). Between the composite layers (2, 3) through direction support members (4) are provided, together with an absorbent material (5). The support members (4) are curved, such that the structure is compliant in the through direction of the structure and has a high bending stiffness perpendicular to the through direction. A structure of this type can be used for making machine rafts with inherent noise and vibration damping, or secondary structures on submarines such as rudders ot fins, with an appropriate absorbent material according to the use. |
