This paper addresses the characterization of marine composites, i.e. polyester resins reinforced with glass fibres in the form of woven and mat layers produced by hand lay-up. Design with these materials requires verification that the mechanical properties determined by tests on small specimens are representative of the behavior of larger structures. A study of scale effects is presented. Results from tensile and flexural specimens over a range from 1 to 10 show no effect of specimen scale on elastic constants. However, measured shear strength determined in tension at 45 deg to the fibres increases with specimen width and scale, rather than decreasing as would be predicted. The scatter in measured properties is shown to be low.
