摘要： A joint member (100) includes a metal component (12) and a composite component (14) which are joined by a joint (10) formed at a non-planar joint interface (18) defined by a textured surface portion (28) of the metal component (12) and a solidified melted area (24) of the composite component (14). The solidified melted area (24) adjacent to the joint interface (18) is characterized by a plurality of non-contiguous solidification boundaries (22) and a non-contiguous dispersion of porosity (16). A method includes forming a textured surface portion (28) on the metal component (12), pressing the textured surface portion (28) into the surface of the composite component (14) to form depressions (32) in the composite component (14), such that a joint interface (18) is defined by the surfaces of the textured surface portion (28) and the composite depressions (32), heating the joint interface (18) to melt an area of the composite component (14) adjacent to the joint interface (18), and solidifying the melted area (24) to the form a joint (10) at the joint interface (18).
