Shape-distorting tooling system and method for curing composite parts

A method of manufacturing a composite article, comprising:

• providing a cure tool having a biasing element fixedly attached thereto, the cure tool having a cure tool coefficient of thermal expansion (CTE), the biasing element having a biasing element CTE that is different than the cure tool CTE, the cure tool configured to support a composite article in an as-designed shape;
• loading a composite article on the cure tool such that the cure tool supports the composite article in the as-designed shape, the composite article being comprised of components having dissimilar CTEs;
• heating the composite article and the cure tool to a curing temperature;
• distorting the cure tool and the composite article thereon into a distorted shape in response to elevating the temperature of the cure tool to the curing temperature due to the difference in the cure tool CTE and the biasing element CTE;
• curing the composite article in the distorted shape;
• and
• cooling the cured composite article such that the cured composite article changes shape from the distorted shape to the as-designed shape due to the dissimilar component CTEs of the composite article.
