Bonding of Carbon Material by Sinter bonding with adhesive resin using direct current heating and pressing

高密度石墨、玻璃碳复合材料、树脂烧结石墨等碳材料将在聚合物电解质燃料电池中得到应用。本研究采用粘结树脂直流加热加压烧结法对上述三种炭材料进行了无气孔的连接研究，主要结果如下：（1）在上述三种炭材料上均获得了无气孔的连接接头。（2）在高密度石墨下获得了与基体石墨的弯曲强度相当的接头强度（4点弯曲强度）。结果表明，在玻璃碳复合材料中，接头强度随各层成分的变化而变化;在树脂烧结石墨中，接头强度随连接温度的变化而变化。（3）这些结果在J.W.S.的Quar.J.报告，第22卷，第1期（2004年）。

Carbon materials such as high density graphite, glassy carbon composite, resin sintered graphite are going to apply for Polymer Electrolyte Fuel Cell. But, Bonding properties of these materials is very poor.Sinter bonding with adhesive resin using direct current heating and pressing was studied in this research.Main results, obtained are as follows :(1)Void free bonding joint is obtaied at above mentioned three carbon materials.(2)Joint strength(4 point bending strength) equivalent to bending strength of base graphite was obtained at high density graphite. It was confirmed that joint strength varied with composition of each layer at glassy carbon composite and bonding temperature at resin sintered graphite.(3)These results were reported at Quar.J.of J.W.S.,Vol22,No1(2004).
