摘要

传统的降落伞织物是由pa66(尼龙型)多长丝纱线组成的。它们能够抵抗高频重复变形，但它们能够吸收在不同气候条件下不适合使用的水。挑战是用PES多长丝纱线制作更多功能的降落伞织物。本工作的主要目的是研究降落伞织物的组成和结构特性对实际最终使用性能的影响。利用基于容重预测的关系来计算体积孔隙度。利用扫描电子显微镜对降落伞织物的形貌进行了评价。比较了Sky Paragliders公司用pa66和PES纱线制备的Ortex伞织物的力学性能和动态力学性能。

PROPERTIES OF PARACHUTE FABRICS FROM POLYAMIDE AND POLYESTER MATERIALS

Traditional parachute fabrics are composed from PA 66 (nylon type) multifilament yarns. They are resistant against high frequency repeat deformation but they are able to absorb water which is not optimal for use in different climatic conditions. Challenge is to create parachute fabrics made of PES multifilament yarns which are more versatile. Main aim of this work is to investigate influence of parachute fabric composition and construction characteristics on real end use properties. The relationships based on the prediction of bulk densities were used to calculate the volume porosity. The morphology of the parachute fabrics was evaluated using scanning electron microscopy. Mechanical and dynamic mechanical properties of parachute fabric Ortex made from multifilament PA 66 and PES yarns by Sky Paragliders company are compared.
