摘要
芳纶纸是制作芳纶纸蜂窝的关键原材料,纸张的结构和性能对蜂窝的性能有着重要的影响。间位芳纶纸表面呈膜状,结构紧密,而对位芳纶纸结构相对疏松,浸渍树脂可以进入纸张内部。影响芳纶纸蜂窝模量最重要的纸张性能是浸渍树脂后纸张模量与厚度的乘积,即Est值。对应相同规格蜂窝,对位芳纶纸的Est值明显高于间位芳纶纸,蜂窝的压缩和剪切模量也较高。对位芳纶纸蜂窝的压缩和剪切强度也都高于间位芳纶纸蜂窝。
Aramid paper was the raw material for the manufacture of aramid paper honeycomb.The structure and performance of the paper have an important impact on the mechanical properties of the honeycomb.The meta-aramid paper had a tight structure and its surface exhibited a form of membrane,however the structure of para-aramid paper was relatively looser,thus it was easy for resin to impregnate into the paper.The product of elasticity modulus and thickness Est of the cell wall after resin impregnation was the key factor that affects the modulus of aramid paper honeycomb.Corresponding to the honeycomb of the same specification,because the Est value of para-aramid paper was much higher than that of meta-aramid paper,the compression and shear modulus of the para-aramid paper honeycomb was also higher than meta-aramid paper honeycomb for same types honeycomb.The compression and shear strength of para-aramid paper honeycomb were also higher than the meta-aramid paper honeycomb.
