摘要

Near the end of its development cycle, this nanostructured metal overlay promises to extend the working life and improve the cost-effectiveness of carbon/epoxy tooling. As composites practitioners well know, tooling for composite parts is a challenge. Metal tools are the most robust option and support rate production, but they need to be carefully engineered to match the coefficient of thermal expansion (CTE) of the composite parts that will be produced. Although conventional tooling steel and aluminum make durable tools, they exhibit much higher thermal expansion than carbon/epoxy parts. However, tools made with Invar, a family of nickel/steel alloys that closely match the GTE of carbon/epoxy materials, are very costly, require long lead times to manufacture and are, therefore, justified only for very high cost and/or high rate parts. Metal tools have the additional disadvantage of being heavy and hard to move and manipulate. With the huge increase in the size and complexity of composite aerospace structures, however -- Boeing's 787 Dreamliner and Airbus' A350 aircraft, as just two examples--parts manufacturers are looking to lower manufacturing costs by improving tooling performance in terms of weight, durability and cost.
