Abstract
A method of manufacturing a composite component comprises forming a core, surrounding the circumference of the core with a first layer of fabric, applying a second layer of fabric having a different coefficient of thermal expansion from the first layer such that the second layer extends around at least a portion of the circumference of the core and curing the component such that the second layer imparts a compressive or tensile force on the core.

A method of manufacturing a composite component comprising:
- forming a skin by surrounding a central region of the component with a first layer of fabric;
- applying at least a second layer of fabric such that the second layer extends around at least a portion of the circumference of the central region, wherein the at least a second layer of fabric includes at least one ply of material having a different coefficient of thermal expansion from the first layer;
- and
- curing the component, whereby the differing coefficients of thermal expansion imparts a compressive or tensile force on the central region after curing.
A method of creating a compressive or tensile force on a composite component comprising:
- forming a skin by surrounding a central region of the component with a first layer of fabric;
- applying at least a second layer of fabric such that the second layer extends around at least a portion of the circumference of the central region, wherein the at least a second layer of fabric includes at least one ply of material having a different coefficient of thermal expansion from the first layer;
- and
- curing the component, whereby the differing coefficients of thermal expansion imparts a compressive or tensile force on the central region after curing.
A composite component comprising:
- a central region;
- and
- a shell surrounding the central region, wherein the shell comprises
- at least one first layer of fabric;
- and
- at least one second layer of fabric separate from the first layer, the at least one first layer extending around the entire circumference of the central region and the at least one second layer extending around at least a portion of the circumference of the central region, wherein the at least a second layer of fabric includes at least one ply of material having a different coefficient of thermal expansion from at the first layer such that the second layer imparts a compressive or tensile force on the central region.
