摘要

Once dubbed by an industry writer the "Rodney Dangerfield" of composites, the 'tooling trade has definitely moved up to new levels of sophistication and earned the industry's respect. The growth of advanced composites applications -- particularly parts with complex contours -- has heightened the need for tooling that affords design flexibility as well as repeatable and accurate performance. No single, ideal material exists that's right for all projects, Every tooling material has its advantages and disadvantages, which must be assessed on a project-specific basis. Certainly, large steel, aluminum and Invar tools are still selected for many critical aerospace projects because of their durability and predictable temperature profile. But, tooling manufacturers continue to push the envelope, demonstrating ingenuity and innovation in the quest for more cost-effective alternatives. As a result, high-performance composites manufacturers have a host of recently introduced tooling materials and design concepts from which to choose.
