Method of fabricating energy absorbing structure

A method of fabricating an energy absorbing structure comprising the steps of (a) winding a continuous resin wetted filament one or more times around an attachment point at one end of a jig to a further attachment point at the opposite end of the jig so as to form a longitudinal strand of pre-determined diameter, (b) passing the filament around and adjacent attachment point and repeating the winding sequence for further pairs of attachment points at opposite ends of the jig so as to build up an array of parallel strands, (c) displacing and tensioning the parallel strands by means of first cross bars substantially at right angles to the strands, (d) winding a second array of parallel strands between the attachment points at opposite ends of the jig over said first cross bars, (e) displacing said second array onto said first array by means of second cross bars lying parallel and inbetween the first cross bars, (f) laying a third array of parallel strands between the attachment points at opposite ends of the jig over said first and second cross bars and (g) curing the structure.
