Abstract
This paper investigates the use of coupon specimens to study the severity of defects in filament would tubes. Composites based on two types of resin are studied, an epoxy and a vinylester. First, the properties of the unreinforced resins are measured. Next the properties of flat filament wound unidirectional glass fibre reinforced composite plates using these resins are determined, and in particular their delamination resistance under mode I loading. These results are then compared with those determined on specimens taken from filament wound tubes with different winding angles (±30°, ±45° and ±60°) and diameters.
