Features of PU Foam Core FRP Sandwich Panels
The composite sandwich panel is composed of PU foam and FRP skin.
The high body strength of extruded PU foam core prevents the damages caused by embedded parts and gives the panel a flat appearance without indentations.
The panel skin is laminated in different directions, keeping the fiber continuity, and reinforces the material in every force direction. This part is lightweight and strong in specific strength and specific modulus. It is water, corrosion, impact, and rubber resistant, and inert to most acids and alkalis. The skin is also recyclable with no gas pollution.
The skin surface is coated with an anti-UV film.
The components of the skin and core can be customized. For example, the skin material can be replaced with aluminum skin.
