Claim 4:
5. A composite sandwich component, comprising:
a first core structure, a second core structure, a third core structure, a top reinforcement layer, and a bottom reinforcement layer, each of the first, second, and third core structures being made of a material selected from the group consisting of polymer foam and wood, each of the first, second and third core structures having a top surface, a bottom surface, a left edge surface, and a right edge surface, wherein:
the top surface of the first core structure is configured with a first plurality of grooves extending from the right edge surface of the first core structure;
the bottom surface of the first core structure is configured with a second plurality of grooves extending from the right edge surface of the first core structure;
the top surface of the second core structure is configured with a third plurality of grooves extending from the left edge surface of the second core structure;
the bottom surface of the second core structure is configured with a fourth plurality of grooves extending from the left edge surface of the second core structure;
the left edge surface of the third core structure is configured with a fifth plurality of grooves extending from the top surface of the third core structure to the bottom surface of the third core structure;
the right edge surface of the third core structure is configured with a sixth plurality of grooves extending from the top surface of the third core structure to the bottom surface of the third core structure;
at least one intersection of a top surface of one of the first, second, and third core structures and one of the left and right edge surfaces of at least one of the first, second, and third core structures, and at least one intersection of a bottom surface of one of the first, second, and third cores structures and one of the left and right edge surfaces of at least one of the first, second, and third core structures are configured with a chamfer;
the first, second, and third core structures are arranged in relation to each other such that the left edge surface of the third core structure abuts the right edge surface of the first core structure, and such that the right edge surface of the third core structure abuts the left edge surface of the second core structure;
the first, second, and third core structures are arranged on the bottom reinforcement layer; and
the top reinforcement layer is arranged on the top surfaces of the first, second, and third core structures.
