大和田碳素工业公司开发了价格只有过去产品的1/3、而压缩强度却为以往品的2倍以上、而且特性优良可短期制作的碳-碳复合材料。在提高复合材料密度的技术方面(申请了专利),成功地提高了关键的碳化收率,以此实现了短期制造特性优良而又廉价的c/c复合材料。现在作为陶瓷等的烧成用的托盘和箱子等的新材料.主要由碳素厂家参入。但由于碳-碳复合材料价格高、制造周期长,因此成了普及的障碍, The company has developed carbon-carbon composites at a price that is only one-third that of its predecessors and whose compressive strength is more than twice that of its predecessor, and that its properties are good for a short period of time. In the field of technology (patent application) for increasing the density of the composite material, the key carbonation yield has been successfully improved, thereby realizing the c / c composite material excellent in short-term manufacturing characteristics and low in cost. Now, it is used as a new material for the firing of ceramics and other trays, boxes, etc. It is mainly made up of carbon manufacturers. However, due to the high price of carbon-carbon composite materials, long manufacturing cycle, it has become a popular barrier,
