Abstract

This study aims to investigate the effect of material type and braiding angle on the performance characteristics of the reinforced multi-layered hose, to manufacture a high-pressure fuel hose. For this purpose, NBR (Acrylo-Nitrile Butadiene rubber)/CPE (chlorinated polyethylene) fuel hose was manufactured using a single-screw extruder and for the production of the reinforcement layer, braiding technology was used. With an attempt to discuss the effect of braiding angle on the performance characteristics of the reinforced multi-layered hose, the speed of the radial braiding machine was altered. E-glass, aramid, carbon, polyester, and basalt yarns were used for the production of the braided layer. Then CPE (chlorinated polyethylene) rubber was extruded for the cover application. Performance properties of the fuel hose such as hardness, ply adhesion, vacuum collapse bursting pressure, and diametric expansion were measured and evaluated according to the requirements of the related standards. The results revealed that, with increased braiding speed, ply adhesion, vacuum collapse, and diametric expansion properties of hoses increase, while hardness, permanent deformation, and bursting pressure of hoses decrease. It has been determined that NBR/Basalt/CPE fuel hose produced in 4m/min braiding speed provided optimum functional and adhesion properties, because of its hardness, permanent deformation, bursting, and vacuum test values at 25°C are within the limit. Additionally, the results were verified by running finite element analysis (FEA) using the ANSYS simulation program.

编织增强高压燃油软管的特性

本研究旨在研究材料类型和编织角度对增强多层软管性能特性的影响，以制造高压燃料软管。为此，使用单螺杆挤出机制造NBR（丙烯腈-丁二烯橡胶）/CPE（氯化聚乙烯）燃料软管，并使用编织技术生产增强层。为了探讨编织角度对增强多层软管性能的影响，改变了径向编织机的速度。E-玻璃、芳纶、碳素、聚酯和玄武岩纱线用于生产编织层。然后挤出CPE（氯化聚乙烯）橡胶用于覆盖物应用。根据相关标准的要求，测量和评估了燃料软管的性能，如硬度、层间附着力、真空破裂破裂压力和直径膨胀。结果表明，随着编织速度的提高，软管的层间粘附力、真空塌陷和径向膨胀性能都有所提高，而软管的硬度、永久变形和爆裂压力则有所降低。已经确定，以4m/min编织速度生产的NBR/玄武岩/CPE燃料软管提供了最佳的功能和粘合性能，因为其硬度、永久变形、爆裂和25°C下的真空测试值都在极限范围内。此外，通过使用ANSYS仿真程序进行有限元分析（FEA）来验证结果。
