<p>The present invention provides an excellent structural material for movable equipment, structural members for building materials, electronic and electrical equipment and the like by bonding an ordinary steel material and an FRP prepreg strongly to each other to facilitate mechanical joining and disassembly using bolts and nuts or the like. It has been found that a steel material having surface configuration with specifically determined ultra-fine irregularities is compatible with an epoxy resin adhesive and exhibits thus strong adhesion. This technique can be utilized to produce a composite component 26 that comprises steel plates 28, as a cover material, integrated with FRP 27. The composite component can be assembled with other metallic members through fastening using bolts 30. Also, structural members having the FRP 27 in the main structure and the steel material at the ends can be easily produced by virtue of the above strong adhesion.</p> |
