据《美国宇航》1986年8月报导:日本“住友”(Sumitomo)化学公司研制出的Ekonol纤维是一种对羟基苯甲酸、对苯二酸和双酚的共集物(其化学成分与Dartco公司研制的“Xydar”液晶聚合物类似)。它是一种新型的、不吸潮的全芳香族液晶聚酯纤维。具有与凯夫拉基本相同的性能:其抗拉强度为3.9GPa(凯夫拉为3.0GPa),拉伸模量为138GPa(凯夫拉为115GPa)。抗冲击强度好,尽管热稳定性尚未达到凯夫拉的标准。Ekonol在400℃左右是可熔的,一般成
According to “Aerospace” reported in August 1986: Japan’s Sumitomo Chemical Company developed Ekonol fiber is a para-hydroxybenzoic acid, a combination of terephthalic acid and bisphenol (its chemical composition and Dartco The company developed “Xydar” liquid crystal polymer similar). It is a new, non-hygroscopic all-aromatic liquid crystal polyester fiber. It has basically the same performance as Kevlar: its tensile strength is 3.9 GPa (Kevlar is 3.0 GPa) and its tensile modulus is 138 GPa (Kevlar is 115 GPa). Impact strength is good, although the thermal stability has not yet reached the Kevlar standard. Ekonol is meltable at about 400 ° C and is generally as good as
