自动铺带和手工铺贴国产T800级碳纤维增强复合材料对比研究和等同性评价

Comparative study and equivalence of domestic T800H carbon fiber composites manufactured by automated tape laying and manual layup method

使用同一批预浸料,采用自动铺带和手工铺贴两种工艺制备复合材料,对比分析了自动铺带和手工铺贴国产T800H碳纤维复合材料性能,并进行了等同性评价与分析。结果表明:自动铺带和手工铺贴的复合材料性能平均值偏差为-2.42%-4.50%,性能差异小;自动铺带和手工铺贴的复合材料强度平均值、强度最小单个值和模量平均值共42项,其中39项等同,3个不等同项性能差异较小,对后续复合材料应用的影响较小。自动铺带和手工铺贴的复合材料性能总体等同。

Domestic T800 H carbon fiber composites were prepared by automated tape laying and manual layup method using one batch prepreg.Mechanical properties of composites were compared,and equivalence evaluation of composites manufactured by automated tape laying and manual layup method was performed.The results show that average value deviation of mechanical properties manufactured by automated tape laying and manual layup method are-2.42%-4.50%.Strength average value,strength minimum individual and modulus average value of composites manufactured by automated tape laying and manual layup method are equally evaluated.There are 42 evaluation items,among which 39 evaluation items are equivalent.The three inequality properties exhibit little difference,and have little influence on the subsequent application of composites.In summary,composite manufactured by automated tape laying is basically equivalent to the composite manufactured by manual layup.
