Abstract
The invention relates to a hollow fibre-reinforced plastic body comprising a curable resin-impregnated winding of high-strength fibres. To provide a strong hollow fibre-reinforced plastic body having a quick-to-make wall thickness the invention proposes that a double-walled shell which surrounds the hollow body interior is made by a first winding of one or more tapes of an uncut double pile cloth having a spaced-apart top cloth and bottom cloth and also binding pile threads which is covered by an outer winding, the windings being impregnated with a curable resin.
Claims18
A hollow fibre-reinforced body comprising:
- a first winding being wound to form an outside wall of a body having a hollow interior, and a cover winding of a high-strength fibres overlying said first winding,
- said first winding including one or more tapes of an uncut double pile cloth, said one or more tapes having side edges positioned in a side by side manner in a winding layer to define a double-walled shell which surrounds said body, said double pile cloth having a spaced-apart top cloth and bottom cloth and also binding pile threads,
- and a curable resin impregnated within said first and cover windings without filling the space between said top and bottom cloths.
A hollow fiber-reinforced body comprising:
- a double-walled structure comprised of a layer of a double-ply cloth tape having spaced apart top and bottom plies, defining a cavity, together with binding pile threads extending therebetween;
- said tape forming said body as a winding having side edges in an edge-to-edge manner with laterally open adjacent edges;
- said tape being impregnated with a curable resin without filling said cavity;
- and
- an inner and outer finishing layer overlaying and adhered to inner and outer surfaces, respectively, of said double-walled structure that surrounds and seals the hollow interior thereof.
A fiber-reinforced hollow body comprising:
- a double-walled structure comprised of a double-ply cloth tape having spaced apart top and bottom plies, defining a cavity therebetween, together with binding pile threads extending therebetween;
- said tape forming said body as a continuous winding having abutting side edges in an edge-to-edge manner with laterally open adjacent edges that collectively define a continuous cavity within said body;
- said tape being impregnated with a curable resin without filling said continuous cavity;
- and
- an inner and outer finishing layer overlaying and adhered to inner and outer surfaces, respectively, of said double-walled structure that surrounds and seals the hollow interior thereof.
