Abstract
The linear viscoelastic parameters — storage shear modulus and loss factor — have been studied between 4.2K and 293K by a torsion pendulum on various fibres (carbon, fibreglass and Kevlar) with different polymeric matrices (epoxies and PEEK) in the unidirectional (UD) composites. The off-axis properties in UD carbon AS4/PEEK and fibreglass/epoxy have been investigated at 0, 30, 45, 60 and 90 degrees on the fibre directions. The influence of low-temperature (the second and the third) glass transitions on loss factors is considered in comparison with the matrix results. The contribution of fibre-matrix interface on loss factor is also discussed at very low temperatures, below 100K.
