Kevlar
Kevlar is an organic fiber (poly-para-phenylene-terephthalamide) in the aromatic polyamide family, produced by DuPont de Nemours [1]. It has a unique combination of high strength, high modulus, toughness and thermal stability. Its remarkable properties are mainly related to the structure developed during the spinning process [2]. It was developed for demanding industrial and advancedtechnology applications. In this work, single Kevlar-29 fibers have been subjected to tensile tests at room temperature using a Universal Fiber Tester developed originally by Bunsell et al. [3], equipped with a load cell of 250 g calibrated from 0 to 100 g, with a precision of 0.01 g. The specimen gauge length was 30 mm and the fiber was gripped between two sets of jaws. Data acquisition used a PC linked to the fiber tester via a National Instrument interface card and WinATS 6.2 software from Sysma. In order to normalize the stress, the diameter of each fiber was systematically measured before each test by using a Mitutoyo LSM-500S laser apparatus, with an accuracy of 0.01 μm.
