In recent decades, carbon fiber, glass fiber, polyester and Kevlar fiber have been utilized to replace the steel shims in conventional steel-reinforced elastomeric isolators (SREIs). This study chose nylon fabrics owing to their extreme low cost, low elastic modulus and good adhesion to rubber, and nine nylon fabric-reinforced elastomeric isolators (N-FREIs) were manufactured with different design parameters. Compression and compression shear tests were, respectively, conducted to investigate the mechanical properties together with their influential factors of the N-FREIs. Results show that the vertical load-carrying capacity of the isolator is high enough to sustain a compressive stress of 10$$MPa without visible damage. The compressive stiffness of N-FREI is much smaller than that of SREI, and the vertical damping ratio under cyclic compression reaches up to 7%. In the compression shear tests, the shear stiffness of the isolator first decreases and then increases as the shear strain increases within 300%, and the equivalent damping ratio varies between 9% and 14% for different sizes of the isolator. Additionally, due to the flexibility and extensibility of the low modulus nylon fabric, both vertical and horizontal stiffness decrease a bit with an increase in the number of fabric layers. Finally, a formula for calculating the horizontal stiffness of N-FREI is proposed, it provides a comprehensive mathematical model to predict the behavior of the N-FREI under horizontal shear conditions.

近几十年来，碳纤维、玻璃纤维、聚酯和凯夫拉尔纤维已被用来替代传统钢增强弹性体隔振器（SREI）中的钢垫片。本研究选择尼龙织物是因为其成本极低、弹性模量低且对橡胶具有良好的粘合性，并采用不同的设计参数制造了九种尼龙织物增强弹性体隔振器（N-FREI）。分别进行了压缩和压缩剪切试验，以研究 N-FREI 的机械性能及其影响因素。结果表明，隔振器的垂直承载能力足以承受 10 的压应力$$MPa 无明显损坏。N-FREI的压缩刚度远小于SREI，循环压缩下的竖向阻尼比高达7%。在压剪试验中，随着剪应变的增加，隔振器的剪切刚度在300%以内先减小后增大，不同尺寸的隔振器等效阻尼比在9%~14%之间变化。此外，由于低模量尼龙织物的柔韧性和延展性，垂直和水平刚度都随着织物层数的增加而略有下降。最后，提出了N-FREI水平刚度的计算公式，为预测N-FREI在水平剪切条件下的行为提供了综合的数学模型。
