Abstract
A composite diving board comprising a composite laminate of fibers in a matrix.
Claims25
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 comprising fibers having a modulus of more than 100 GPa and the central core comprising a material different from said fibrous material.
