本文给出了通过扩散连接制备的交叉铺层和编织铜基碳纤维复合材料（Cu-C-f MMCs）的热膨胀数据。在两个垂直的平面内方向的板样品的热膨胀进行了测量。对于交叉层样品（57体积%纤维）在加热/冷却期间，在-20至300 ℃之间的平均热膨胀系数（CTE）从约6.5 × 10（-6）/℃变化到3.5 × 10（-6）/℃。面内CTE随着纤维含量的减少而增加。具有碳纤维编织排列的复合材料在升高的温度下显示出稍高的CTE。(C)2001爱思唯尔科技有限公司版权所有。
This paper presents thermal expansion data for cross-ply and woven copper matrix-carbon fibre composites (Cu-C-f MMCs) that were prepared by diffusion bonding. Thermal expansion was measured in two perpendicular in-plane directions of plate samples. For cross-ply samples (57 vol.%fibres) the mean coefficient of thermal expansion (CTE) between -20 and 300 degreesC changed from approximately 6.5 x 10(-6)/degreesC to 3.5 x 10(-6)/degreesC during heating/cooling. The in-plane CTE increases with decreasing fibre content. Composites with woven arrangement of carbon fibres show a slightly higher CTE at elevated temperature. (C) 2001 Elsevier Science Ltd.
