Abstract

The present invention is a method of forming a fiber reinforced thermoset composite boom section or pipeline. The method comprises first creating a form and coating the form with a wax layer. A plurality of fiber reinforced thermoset composite material layers is then formed over the form. After the thermoset composite material layers cure, the form is removed.

Claims (25)

1 . A method of forming a fiber reinforced thermoset composite boom section, the method comprising:

creating a form having a longitudinal axis by attaching internal sandwich block-outs longitudinally to a mandrel;

coating the form with a wax layer;

forming a plurality of fiber reinforced thermoset composite material layers over the form;

allowing the thermoset composite material layers to cure; and

removing the form.

2 . The method of claim 1 wherein one fiber reinforced thermoset composite material layer is formed by winding an S-2 glassed filament wetted with vinyl ester resin in a helical pattern at an angle approximately 20° from the longitudinal axis of the form.

3 . The method of claim 1 wherein one fiber reinforced thermoset composite material layer is formed by winding a carbon filament wetted with epoxy resin in a polar pattern at an angle approximately 0° from the longitudinal axis of the form.

4 . The method of claim 1 wherein one fiber reinforced thermoset composite material layer is formed by winding an aramid filament wetted with a vinyl ester resin in a helical pattern at an angle approximately 30° from the longitudinal axis of the form.

5 . The method of claim 1 wherein one fiber reinforced thermoset composite material layer is formed by winding an S-2 glass filament wetted with an epoxy resin in a helical pattern at an angle approximately 60° from the longitudinal axis of the form.

6 . The method of claim 1 wherein the plurality of fiber reinforced thermoset composite layers are formed about the form at an angle ranging from approximate 20° to 90° from the longitudinal axis of the form.

7 . The method of claim 1 wherein forming the plurality of fiber reinforced thermoset composite material layers comprises forming a first layer including glass fibers in a vinyl ester matrix.

8 . The method of claim 1 wherein forming the plurality of fiber reinforced thermoset composite material layers comprises forming a second layer including carbon fibers in an epoxy matrix.

9 . The method of claim 1 wherein forming the plurality of fiber reinforced thermoset composite material layers comprises forming a third layer including aramid fibers in a vinyl ester matrix.

10 . The method of claim 1 wherein forming the plurality of fiber reinforced thermoset composite material layers comprises forming a fourth layer including glass fibers in a vinyl ester matrix.

11 . The method of claim 1 wherein forming the plurality of fiber reinforced thermoset composite material layers comprises:

winding an S-2 glass filament wetted with vinyl ester resin in a helical pattern at an angle approximately 20° from the longitudinal axis of the form;

winding a carbon filament wetted with epoxy resin in a polar pattern at an angle approximately 0° from the longitudinal axis of the form;

winding an aramid filament wetted with a vinyl ester resin in a helical pattern at an angle approximately 30° from the longitudinal axis of the form; and

winding an S-2 glass filament wetted with an epoxy resin in a helical pattern at an angle approximately 60° from the longitudinal axis of the form.

12 . A method of forming a fiber reinforced thermoset composite pipeline, the method comprising:

creating a form having a longitudinal axis by attaching internal sandwich block-outs longitudinally to a mandrel;

coating the form with a wax layer;

forming a plurality of fiber reinforced thermoset composite material layers over the form;

allowing the thermoset composite material layers to cure; and removing the form.
