Abstract
This invention is directed toward a surfboard made from at least two different types of foam and laminating methods. The general invention has a central core, preferably of EPS foam, and two outside panels—located either on the sides, or rails, of the blank, or above and below the central core. In a preferred embodiment, the panels are made from PU foam, and the panels are attached to the central core through a laminating substrate, which can be another type of foam or copolymer, such as TPU, or a harder material such as plastic or wood. The invention produces a blank that can be shaped into a surfboard that is both strong and flexible.
Claims10
A multi-density surfboard blank, comprising a central core, two outside panels, where the central core is made from a foam of a first density, and the two outside panels are made from a foam of a second density, and the first density is different from the second density, where the central core comprises a core front, a core back, two core sides, a core top and a core bottom, where the two outside panels are connected to the two core sides, with one outside panel connected to each of the two core sides, where each of the two core sides additionally comprises a cut-out, where each of the outside panels comprises an inner side and an outer side, where the inner side is connected to the cut-out of the core, where the inner side of each outside panel is configured to mate with the cut-out of the core, additionally comprising two substrates, where one substrate is located on each of the two sides of the central core, and where the two substrates connect the two outside panels to the two cut-outs of the central core, where the central core is manufactured from EPS foam and the two outside panels are manufactured from PU foam.
