Hexcel Corp has launched the HexWeb CRPAA-5052-F80-12.0 Vented Flex-Core, a new aluminum honeycomb product engineered for complex, contoured structures. The material offers integrated venting capabilities to manage pressure and outgassing during flight operations.
Why it matters
This new material significantly reduces the need for complex machining and splicing in composite manufacturing. By improving formability, it allows aerospace engineers to more efficiently create aerodynamic components that require precise shaping.
The core is manufactured from 5052 aluminum alloy and features a phosphoric acid anodized coating for corrosion resistance. It supports operational service temperatures reaching 177°C while maintaining a density of 12.0 lb/ft³.
The players
Hexcel Corp
Headquartered in Stamford, this company is a major producer of advanced lightweight composite materials and structural components for the aerospace and defense industries.
The details
The product features an integrated venting architecture that addresses pressure differentials commonly encountered in aerospace environments. Its design provides the flexibility necessary to form contoured structures while minimizing the manufacturing complexity associated with traditional core materials.
Timeline
Hexcel Corp announced the product launch on September 28, 2026.
The Big Picture
This development represents a technical evolution of Hexcel's HexWeb aluminum honeycomb product line. It shifts design paradigms by integrating pressure management directly into the core material, rather than requiring auxiliary venting systems.
Future aerospace components utilizing this material may see reduced manufacturing costs and weight through simplified structural design. These improvements could lead to more efficient aircraft production cycles and lighter airframe assemblies.
The takeaway
Advancements in core material flexibility allow manufacturers to push the boundaries of aerodynamic design without sacrificing structural integrity. Engineers should note that the integrated venting design may eliminate the need for secondary processes in future pressurized flight structures.
