More Information
Summary:The utility model relates to a gradient foam layer board, top layer panel and middle core including upper and lower both sides, the top layer panel be fibre reinforced resins base combined material, the core be the synthetic foam of a gradient structure, it fills compound forming in the organic resin base member by hollow microsphere, and hollow microsphere's volume loading changes along vertically taking place the gradient gradually. Synthetic foam through using the gradient structure is as the core, the utility model discloses a better realization of foam layer board high strength and the coordination between the high energy -absorbing characteristic of sandwich panel, compare as compound sandwich panel of the tradition of core and the sandwich panel of introducing rubber in synthetic foam core with using foam simultaneously, the utility model discloses a foam layer board has lower water absorption rate.
