Woven Composite Laminates

Woven composites are well-known for their good transverse properties and for their high fracture toughness. The damage mechanisms leading to delamination in woven composites are identified in mode I and II and are compared with those occurring in unidirectional laminates. The influence of several parameters, including the draping sequence and the fibre / matrix interface on the fracture toughness of woven composite laminates is studied. Pure Mode I and Mode II tests are carried out on several carbon/epoxy and glass/epoxy woven composites configurations and the differences observed are discussed from a fractographic point of view. The study illustrates the high fracture toughness of the composites made of woven fabrics as well the influence of the orientation of the plies, the nature of the fibres and the addition of an adhesive film.

Woven Composite Laminates

‘C’-shaped test specimens have been used to find the interlaminar strength of woven carbon/epoxy composite laminates in tension and in combined tension with minor transverse tractions. An analytical solution for the stress distribution within the “C” specimen, of arbitrary lay-up, is developed to permit a rigorous interpretation of the results, which confirm that the presence of relatively minor through-thickness stresses will have a profound influence on the strength of the component.
