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.
Claims14
A composite component comprising:
- a central region;
- and
- a shell surrounding the central region, wherein the shell comprises
- a first layer of fabric;
- and
- a second layer of fabric separate from the first layer of fabric, the first layer of fabric extending around the entire circumference of the central region and the second layer of fabric extending around at least a portion of the circumference of the central region,
- wherein the second layer of fabric includes a ply of material forming at least part of said fabric of the second layer of fabric having a different coefficient of thermal expansion from said fabric of the first layer of fabric such that the second layer of fabric imparts a compressive or tensile force on the central region.
