Composite diving board

A composite diving board comprising:

• a top surface, a bottom surface, a base end, a tip end, a length along a longitudinal axis of the board from its base end to its tip end, a width transverse to the longitudinal axis, and a thickness;
• a central core, an upper composite laminate between the top surface and the central core, and a lower composite laminate between the bottom surface and the central core, to define a sandwich composite of the upper composite laminate, central core, and lower composite laminate;
• each of the upper and lower composite laminates comprising a fibrous material and the central core comprising a material different from said fibrous material;
• wherein the core comprises a foam material which has a density of at least about 60 kg/m3, a compressive strength of at least about 0.8 MPa, a compressive modulus of at least about 50 MPa, a shear strength of at least about 0.5 MPa, and a shear modulus of at least about 15 MPa.
