Description
樹脂の低透過性を試験する方法には、様々な方法があるが、燃料用チューブに用いる樹脂について低透過性を試験する方法の代表例には、SHED試験機を用いて行うCARB DBL法がある。
第1実施形態
図1は、多層樹脂チューブの横断面を示す。この多層樹脂チューブは、外側から順に外層の第1層と、中間の接着層である第2層と、最内層の第3層からなる3層構造の樹脂チューブである。第1実施形態では、層の基本構造として燃料に直接触れる最内層の第3層が低透過性の樹脂を材料とする層となっていいる。そして、この第3層は、低透過性樹脂層であることに加えて、長繊維状の導電フィラーを添加した樹脂からなる導電性樹脂層でもある。第1層の方は、第3層のように低透過性を強化した樹脂層とはなっていない。第3層は、低透過性の熱可塑性樹脂に電導性を付与するために、カーボンナノチューブまたは炭素長繊維が添加された樹脂から形成されている。
次に、図4は、本発明の第2の実施形態による多層樹脂チューブの横断面図である。
次に、図5は、本発明の第3の実施形態による多層樹脂チューブの横断面図である。
Claims (7)
