Dia-Stron Ltd. (Broomall, PA, US) will showcase its automated modular testing systems for single fibers and filaments. The company now offers a new tensile testing configuration based on the LEX820, a high resolution tensile tester for single fibers and filaments. In this configuration, fiber samples can be measured in uniaxial tensile mode while immersed in a liquid. The immersion cell can be raised and lowered enabling dry or wet tensile measurements. Dia-Stron also developed a cassette hotel, capable of holding up to 200 samples, allowing for 24/7 measurement capability. With increased pressure on internal testing departments to improve testing throughput times and capacity, the cassette hotel can be loaded live during measurements. The Dia-Stron LEX/LDS System is a cassette-based automated dimensional and tensile instrument for composite fibers and filaments.
