Measurement of Viscoelastic Properties of PEEK/IM7 by Dynamic Mechanical Analysis (DMA)

摘要

DMA measured viscoelastic properties data of PEEK/IM7 are presented. Experimentsrnare conducted on beams using the three-point bending mode. Unidirectional beams withrndifferent fiber orientations are tested showing property changes relating to temperature andrnfrequency. Viscoelastic properties, including storage modulus (E'), loss modulus (E") andrndamping function (tan δ) as the function of fiber orientation of laminated composite materials arerndetermined.
