    • PURPOSE: Provided is a board formed with carbon base metal composite material having a thermal conductivity of 150 w/(m.K) or more, a thermal expansion coefficient of 4 x 10-6/deg.C-12 x 10-6 and elastic modulus in the surface direction of 50 GPa or less and suitable to a substrate for electronic devices. CONSTITUTION: The board formed with carbon based metal composite material is composed of the carbon base metal composite material produced by impregnating aluminum, copper, silver or alloy thereof into a carbon formed body containing graphitized grain or a carbon formed body containing carbon fiber with molten material forging. The producing method of the carbon base metal composite formed board is executed by bringing the carbon formed body into contact with molten aluminum, molten copper, molten silver or molten alloy thereof under pressure to impregnate the molten metal into the carbon formed body.
    • 目的:提供一种由碳基金属复合材料形成的导热率为150w /(mK)以上,热膨胀系数为4×10 -6 /℃〜12×10 -6的弹性模量 在50GPa以下的表面方向上,适用于电子器件用基板。 构成:由碳基金属复合材料形成的板由通过将铝,铜,银或其合金浸渍到含有石墨化晶粒的碳成形体中而制成的碳基金属复合材料或含有碳纤维的熔融材料的碳成形体 锻造。 通过使碳成型体与熔融铝,熔融铜,熔融银或其熔融合金在压力下接触以将熔融金属浸渍到碳成形体中来进行碳基金属复合成型板的制造方法。
