Introduction
HexWeb® honeycomb is a lightweight core material designed for structural stiffening in aerospace and industrial applications. It is used in aircraft components, railway carriages, marine bulkheads, and more. The guide assists in selecting the appropriate honeycomb type for specific applications, with detailed information available in product data sheets.

Key Features
- Exceptional stiffness and strength with minimal weight.
- Available in various cell sizes and densities.
- Made from fiberglass, aluminum, and aramid mechanical papers.
