摘要： PURPOSE:To manufacture a vibration damping metal sheet having a large bonding strength between a synthetic resin layer and a metal sheet, by a method wherein molten synthetic resin is extruded from a die so as to have the shape of a film while the extruded film is inserted between two sheets of metal sheet to ply and bond them by pressure through thermal pressure bonding rolls, thereafter, control cooling for them is effected. CONSTITUTION:Synthetic resin is a heat sensitive type synthetic resin having vibration-damping properties in the employing circumstance temperature of the vibration damping metal sheet from a normal temperature to a medium temperature and the synthetic resin, consisting of modified vinyl acetate resin with 2.3mol% of amount of modification from alkali to acid, for example, added with 15wt% of dibutyl phthalate as a plasticizer, is employed. The synthetic resin is molten under the temperature of 120 deg.C to extrude it from a die into the shape of a film by an extruder 4 while the film type resin is introduced between two sheets of metal sheets 1, 1' between hot pressure bonding rolls 3, 3 and the film is laminated with the metal sheets 1, 1'. The laminate passes through hot compression rolls 5, 5 heated to 180 deg.C and bonding is effected here. Further, the laminate is cooled to about 100 deg.C and bonding is effected here. Further, the laminate is cooled to about 100 deg.C while pressing it by a roll under a first cooling process 7, thereafter, is cooled to a normal temperature by a second cooling process 8. Thus, a vibration damping metal plate, bonded strongly under a stabilized condition without accompanying any strain, may be obtained.

摘要： PURPOSE:To manufacture a vibration-damping steel sheet, excellent in vibration- damping performance, provided with a high bonding strength, inexpensive and prominent in resistance welding properties, by a method wherein grit blasting process is applied previously on a bonding surface of a steel sheet and a vibration-damping resin. CONSTITUTION:The processed surface of a steel sheet, formed by applying grit blasting process, is formed irregularly with recesses 1 and projections 2, and large-sized and small-sized recesses 1 and projections 2 are scattered while the edge of the projections 2 and the trough of the recesses 1 areprovided with acute angles. Accordingly, contacting area between conductive metallic powder 4, mixed in vibration-damping resin 3, and the steel sheets 5a, 5b is increased whereby a good conductivity between respective steel sheets 5a, 5b may be secured, even when the metallic powder 4 is small particles in a small amount. Further, when the steel sheets 5a, 5b are pressed under heating through the vibration-damping resin 3, the sharp recesses and projections develope a large anchor effect, in addition to the effect of the electric conductivity, whereby a high bonding strength may be obtained. The same things may be applied even in the case when metallic fibers are employed.

摘要： PURPOSE:To improve the rigidity of a composite metallic plate interposed with a thermoplastic resin between metallic plates for bridges, etc., without degrading its vibration damping effect by spot welding said plate with metallic bar materials penetrated therethrough. CONSTITUTION:A composite steel plate 1 consists of the sandwich construction wherein a viscoelastic thermoplastic synthetic resin 3 is interposed between steel plates 2, 2. Through-holes 4 are punched at every pitch to the plate 1, and after metallic bar materials 5 are driven and fitted into the respective holes 4, electrode tips 6 of a spot welder are brought into abutment on both ends of the respective bar materials 5, and electricity i conducted, whereby these are welded with the bars 5. Then, the side faces of the bar materials 5 and the wall surfaces of the holes 4 of the plates 2, 2 attain a melt-stuck state, and the plates 2, 2 are joined surely.

摘要： PURPOSE:To minimize the amt. of costly cladding materials to be used and to obtain a corrosion resistant clad steel pipe having high quality inexpensively, by forming only the cladding metals on both marginal sides that form the seam of a clad steel plate (or steel strip) to a thick wall. CONSTITUTION:A clad steel plate is produced by cladding a steel base material 2 and a cladding metal 3 consisting of a corrosion resistant raw material. The thickness over the entire part thereof is made roughly uniform, and the cladding material 3 in the central part is formed at the min. wall thickness t1 required for forming a corrosion resistant covering. The wall thickness t2 on both marginal sides 3a, 3b to be welded of the cladding metal is increased so as to provide the sound covering of the cladding metal after welding. The wall thickness on both marginal sides of the material 2 is correspondingly decreased. The widths Wa, Wb in the thick wall parts on the sides 3a, 3b are made larger than at least the widths allowing for the margins for edge preparation and the width of penetration in welding stage.
