<p>A fiber reinforced composite article (10), comprises a matrix and reinforcing fibers and is subjected during operation concurrently to a plurality of temperatures and stresses, varying between a plurality of regions (12, 14) of the article (10), and experiences different stresses concurrently in different regions (12, 14) of the article (10). The article (10) is provided with fiber reinforcement of a strength in each region (12, 14) greater than the stress experienced in that region (12, 14). Such fiber reinforcement is provided through a member (20) for inclusion in the matrix, for example in the form of at least one of a fabric, weave, braid, lay-up, etc. One form of such an article (10) for use at relatively high temperatures is a turbine engine component, for example a gas turbine engine exhaust flap. Another form of such an article (10) is a gas turbine engine blading component. <IMAGE></p> |
