WT5BZ]Flexural properties of C/C composites was investigated at the temperature of 20℃ to 1400℃ It′s found that as the span to depth ratio increases, the bending strength rises but the shear strength reduces When the span to depth ratio is greater than 8, the bending strength tend to be constants The span to depth ratio is independent on temperature in the range of 20℃ to 1400
结果表明 ,在室温下随着跨厚比的增加 ,C/C复合材料层合板的弯曲强度亦增加 ,而剪应力却逐步下降 ;但当跨厚比≥ 8时 ,C/C复合材料层合板的弯曲强度不再增加 ,剪应力下降逐渐减缓并保持一恒定值 ;从室温到 140 0℃高温范围内 ,温度对 C/C复合材料层合板的临界跨厚比的影响甚小。
