Abstract
A method, apparatus, and system for managing a composite part. An acceptable level of a warpage is identified for the composite part. The warpage for the composite part is a change in the composite part as manufactured that deviates from design specifications for the composite part. Orientations in a stacking sequence for plies in the composite part are selected that result in the composite part having the acceptable level of the warpage and a desired strength to form selected orientations. The composite part is manufactured using the selected orientations.
Claims27
A method for managing a composite part, the method comprising:
- identifying an acceptable level of a warpage for the composite part, wherein the warpage for the composite part is a change in the composite part as manufactured that deviates from design specifications for the composite part;
- and
- selecting orientations in a stacking sequence for plies in the composite part to form selected orientations in the stacking sequence such that manufacturing the composite part using the selected orientations in the stacking sequence results in the composite part having the acceptable level of the warpage and a desired strength.
A composite part system comprising:
- a computer system;
- and
- a composite part designer in the computer system, wherein the composite part designer is configured to:
- identify an acceptable level of a warpage for a composite part, wherein the warpage is a change in the composite part as manufactured that deviates from design specifications for the composite part;
- and
- select orientations in a stacking sequence for plies in the composite part to form selected orientations in the stacking sequence such that manufacturing the composite part using the selected orientations in the stacking sequence results in the composite part having the acceptable level of the warpage and a desired strength.
A product management system comprising:
- fabrication equipment;
- and
- a controller in communication with the fabrication equipment, wherein the controller is configured to control the fabrication equipment to manufacture a composite part using a part design that has selected orientations in a stacking sequence for plies in the composite part that result in the composite part having a warpage with an acceptable level of the warpage and a desired strength, wherein the warpage is a change in the composite part when manufactured that deviates from design specifications for the composite part.
