The use of composites for deep sea applications requires a thorough understanding of the behaviour e of these materials. While several studies have examined the influence of pressure on in-plane i v e properties few data are available for the interlaminar fracture behaviour. This paper presents results r r from such tests performed in a specially designed pressure vessel mounted on a standard test e e p machine, which allows pressures up to 1000 bars (100 MPa) to be applied during mechanical testing. g n Mode I and Mode II tests have been performed on a unidirectional IM7/977-2 carbon/epox
