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.
