Abstract
Official abstract text for this publication.
A method and an apparatus of manufacturing flexible pipe body ( 100 ) is disclosed. The method includes the step of winding at least one composite body having a substantially helical innate shape around an underlining pipe layer.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of providing a helical composite body, comprising the steps of: providing a resin impregnated fibre by pulling at least one fibre element through a resin bath; and providing a cured composite body by curing the resin impregnated fibre in a linear die; whereby the cured composite body is provided in a helical shape by varying an axial and/or torsional tension along a length and/or width of the impregnated fibre. 2. The method as claimed in claim 1 , further comprising the steps of: offsetting an effective location of a pulling force on the fibre element from a straight through path associated with the die. 3. The method as claimed in claim 1 , further comprising the steps of: selectively rotating a puller unit pulling the cured composite body with respect to the die. 4. The method as claimed in claim 1 , further comprising the steps of: varying at least one operating parameter associated with a step of curing the impregnated fibre by selecting a changing temperature profile in at least one region of the die. 5. The method as claimed in claim 1 , further comprising the steps of: providing at least one transverse fibre and/or transverse fabric with the impregnated fibre.
