英语翻译
Wooster reported on composites of cyanate esters and micrometer-sized fused silica,showing improved mechanical properties and reduced CTE for high loadings.
“reduced CTE for high loadings” 不太明白
高承载力(高载荷) 和负载率都解释不通
是否指“大量”,完整译下这两句
Wippl et al.investigated the reinforcement of high-temperature thermosets (bismaleimides,polyimides,and cyanate esters) with high loadings of fused silica,silicon nitride,and alumina,and CTEs as low as 15 ppm/℃ were reported for volume fractions up to 80%.
Wooster等报告了微米级石英/氰酸酯复合材料,在高填料量时机械性有所改善,热膨胀系数有所下降.
Wippl等研究了用高填料量石英、氮化硅、和氧化铝作为增强材料的耐高温热固性塑料(双马来酰亚胺,聚酰亚胺,氰酸酯和),体积分数达80%时CTE可降低至 15 ppm/℃.
