 Core is a new construction material, which is made of PP based on honeycomb bionic principles. Compared with traditional materials, it has these remarkable advantages like light-weight, high compressive strength, environmentally friendly, waterproof, moisture-proof and corrosion resistant etc. Moreover, it can be attached with various of face materials (such as FRP,wood grain sheet, aluminum sheet, stainless steel sheet, marble sheet, rubber sheet etc.) . Therefore, it can extensively replace traditional materials, and it can be widely used in these areas like van, high-speed train, aerospace, yachting, home furnishing and mobile architecture etc.
