초록

A composite article includes a composite member, a flexible member and at least one shape memory material member. The composite member has longitudinally extending fibers in a matrix material. The at least one shape memory material member extends substantially parallel to the composite member and the flexible member is positioned between the composite member and the at least one shape memory material member to bond the at least one shape memory material member to the composite member. The composite article is particularly suitable for use as a tab for an...
