LIGHTWEIGHT REINFORCED PHENOLIC STRUCTURAL SANDWICH PANEL BASED ON ARAMID HONEYCOMB CORE AND METHOD

摘要

A structural panel comprises phenolic skins formed over a honeycomb core. The skins are bonded to the honeycomb under vacuum and heat, providing a panel capable of forming to desired shapes. The panel is 30% lighter than aluminum honeycomb panels of similar thickness, equivalent in strength to aluminum honeycomb panels, and meets the very stringent fire, smoke and toxicity norms of the industry. Additionally the product also reduces the thermal load, has very high heat resistance and is corrosion resistant. The use of this product is not limited to flat profiles, but can also be used to mould double curved or other three dimensional profiles.
