Multi-layer composite part

Abstract

A laminated composite part including a first member comprising a predetermined mating surface, and a second member that is made of an elastically deformable resin material, that comprises a plate-like portion substantially parallel to the mating surface and including a multiplicity of protrusions formed integrally with the plate-like portion so as to protrude toward the mating surface so that space is created between the plate-like portion and the mating surface, and that is set on the first member such that the protrusions contact the mating surface, the laminated composite part having cushioning properties as tip ends of the protrusions are pressed by the mating surface and elastically deformed. The multiplicity of protrusions are formed so as to spread all over the plate-like portion, and a deformation guide portion is provided for each protrusion in a region of the mating surface the tip end of the protrusion contacts, so that when the protrusion is pressed, the deformation guide portion causes the tip end of the protrusion to slide and move along the mating surface in one direction determined for each protrusion and flexurally deforms the protrusion in the one direction.
