An example of a composite structure is a containment case 2 for a gas turbine engine 1 which comprises an annular housing 3 and an annular flange 4 which is integral with and is positioned at an end of the housing 3. The housing 3 comprises composite material which includes tape 9 laid in the circumferential direction of the housing. The flange 4 comprises composite material which includes tape 8 laid at an oblique angle to the circumferential direction of the flange 4 and/or tape 7 laid at a perpendicular angle to the circumferential direction. The flange 4 does not include tape 9 laid in the circumferential direction of the flange, because such tape would impede the forming of the flange material to form the flange. |
