Transverse Tensile, Compression and In-Plane Shear Behaviors of Zylon Fiber-Reinforced Polymer

Abstract

The Zylon fiber-reinforced polymer (ZFRP) reinforcements of pulsed magnets often manifest transverse and shearing failure modes under ultrahigh magnetic fields, resulting in unintended disruptions of the magnet system. Nevertheless, the transverse tensile, compression, and in-plane shear behaviors of ZFRP remain insufficiently understood, impeding efforts to elucidate the underlying failure mechanisms and enhance magnet performance. To address this knowledge gap, this paper undertook a comprehensive mechanical tests of ZFRP. Specimen were fabricated using the autoclave-forming technique, followed by transverse tensile, compression and in-plane shear tests conducted at 213 K, 243 K, and 296 K. The elastic modulus and stress-strain response were both characterized, and the influence of the fiber-filling factor were also discussed.
