本発明は車輌用鋼板に関し、さらに詳しくは、耐蝕性、
制振性に優れた車輌用鋼板に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a steel plate for vehicles, and more specifically, to corrosion resistance,
This invention relates to steel plates for vehicles with excellent vibration damping properties.
−殻に、車輌用材料、特に、自動車用材料は最近、自動
車の安全規制、燃費規制、耐蝕規制、騒音規制等がとみ
に厳しくなってきており、従って、累月の軽量化、耐蝕
性改善、制振性の付与等が要望されている。-In recent years, vehicle materials, especially automobile materials, have become subject to increasingly strict regulations such as automobile safety regulations, fuel consumption regulations, corrosion resistance regulations, and noise regulations. There is a demand for vibration damping properties.
このため、高張力鋼板、表面処理鋼板、或いは、ラミネ
ー）鋼板等が開発されている。For this reason, high-tensile steel plates, surface-treated steel plates, laminated steel plates, and the like have been developed.
しかしながら、−ｌ二記した材料は夫々単一の要求には
対処できるが、製造工程が煩雑な割には飛躍的な性能改
善はみられない。However, although each of the materials mentioned above can meet a single requirement, dramatic performance improvements are not seen despite the complicated manufacturing process.
例えば、耐蝕性の改善を目標に開発された表面処理鋼板

よる溶解消耗が激しく、メッキ層を厚くする必要があり
軽量化には逆行する。また、制振鋼板は軽量化に対して
は満足で軽るが、成形時にシワが発生し易く、苛酷な成
形には適さないし、耐蝕性にも劣るという問題がある。For example, surface-treated steel sheets developed with the aim of improving corrosion resistance are plated with zinc on the surface of the steel, but the corrosion of the zinc leads to severe dissolution and wear and tear, requiring a thicker plating layer to reduce weight. Go backwards. Further, although damping steel plates are satisfactory in terms of weight reduction, they tend to wrinkle during forming, are not suitable for severe forming, and have poor corrosion resistance.

て車輌用鋼板を製造する。A steel plate for vehicles is manufactured by heating and bonding a soft aluminum sheet (or aluminum alloy sheet) to one side (or both sides) of the above material, that is, a steel plate with excellent formability, using a thermocompression type synthetic resin. .
この本発明に係る車輌用鋼板の諸性質、特に、車輌用と

ことができる。(1) Regarding corrosion resistance, as a material for vehicles, it is exposed to extremely severe corrosive environments regardless of whether it is hot or cold. Corrosion of the steel plate is prevented, and a part of the molded part of the vehicle steel plate is brought into contact with screws or ultrasonic pressure welding.(2) Regarding peeling resistance, thermocompression bonding synthetic resin Since it is water permeable, water that passes through the thin resin film reaches the surface of the steel plate, corroding the surface and reducing adhesive strength. Therefore, it is necessary to use a steel plate that has undergone surface treatment. Furthermore, even if the aluminum sheet on the outer surface is damaged, damage to the steel sheet can be avoided directly because of the thermocompression-bonded synthetic resin layer.

い。(4) Regarding formability, a 5PCC-3PCE grade steel plate with excellent formability is bonded to a 1 grade soft aluminum sheet with good formability using a thermocompression type synthetic resin with an adhesive strength of 5 Kg/15 Iam width. By laminating the above, it can withstand severe forming for vehicles.Furthermore, if more rigidity is required for vehicles, an aluminum alloy sheet such as 5052.5182-0 can be laminated. Obtaining the desired performance.The thicker the thermocompression bonding synthetic resin, the lighter it will be and the better the vibration damping properties, making it preferable as a material for vehicles.However, as it becomes thicker, the moldability will deteriorate, so the shape of the part and its intended use will be reduced. An appropriate thickness may be selected depending on the situation.
