Claims
- 1. A containment ring for a gas turbine engine comprising:
- a substantially rigid cylinder having an outer most cylinder or surface;
- a plurality of layers of woven fibrous material positioned adjacent said outermost surface of the substantially rigid cylinder and each layer in the underlying portion comprising a plurality of circumferentially arranged discrete pieces of woven fibrous material positioned adjacent one another; and
- a further plurality of layers of woven fibrous material arranged over the first plurality of layers, said further layers being wound from a continuous length of material.
- 2. A containment ring as claimed in claim 1 in which the woven fibrous material comprises an aromatic polyamide fibre woven into an elongated tape.
- 3. A containment ring as claimed in claim 1 in which the woven fibrous material comprises, glass fibre, carbon fibre, or metallic fibre from which is woven an elongated tape.
- 4. A containment ring as claimed in claim 1 in which the substantially rigid cylinder comprises a relatively thin section light-weight metal structure.
- 5. A containment ring as claimed in claim 1 in which the substantially rigid cylinder comprises a relatively thin section structure manufactured from a fibre reinforced resin material.
- 6. A containment ring as claimed in claim 1 in which the plurality of layers of woven fibrous material are covered with an impervious layer of material comprising a metallic or non-metallic skin or alternatively a resin layer.
- 7. A containment ring for a gas turbine engine comprising:
- a substantially rigid cylinder having an outer most cylinder or surface;
- a plurality of layers of woven fibrous material positioned adjacent said outermost surface of the substantially rigid cylinder and each layer in the underlying portion comprising a plurality of circumferentially arranged pieces of material positioned adjacent one another;
- a further plurality of layers of woven fibrous material arranged over the first plurality of layers, said further layers being wound from a continuous length of material; and
- means for placing the pieces of woven fibrous material upon the cylindrical surface, the pieces being secured together in the form of an elongated tape by means of stitching.
- 8. A containment ring for a gas turbine engine comprising:
- a substantially rigid cylinder having an outer most cylinder or surface;
- a plurality of layers of woven fibrous material positioned adjacent said outermost surface of the substantially rigid cylinder and each layer in the underlying portion comprising a plurality of circumferentially arranged pieces of material positioned adjacent one another;
- a further plurality of layers of woven fibrous material arranged over the first plurality of layers, said further layers being wound from a continuous length of material; and
- means for placing the pieces of woven fibrous material upon the cylindrical surface, the pieces being secured together in the form of an elongated tape by a backing layer to which the pieces of woven fibrous material are secured.
- 9. A containment ring for a gas turbine engine comprising:
- a substantially rigid cylinder having an outermost cylinder or surface;
- a plurality of layers of woven fibrous material positioned adjacent said outermost surface of the substantially rigid cylinder and each layer in the underlying portion comprising a plurality of circumferentially arranged pieces of material positioned adjacent one another; and
- a further plurality of layers of woven fibrous material arranged over the first plurality of layers, said further layers being wound from a continuous length of material;
- wherein, to facilitate the placing of the pieces of woven fibrous material upon the cylindrical surface, said pieces are secured together in the form of an elongated tape by means of a temporary fastening.
