✦ Synopsis

This article presents a simulation scheme to predict the effect of fibre anisotropy on composite tensile failure strength at room and low temperatures. The simulation model combines the shear lag equation with the chain of bundles probability model to describe the composite failure behaviour. The effect of fibre anisotropy on thermal stresses developed in composite constituents due to cooling to low temperatures is considered. The failure strength of composites composed of fibres with different degrees of anisotropy is obtained and comparisons are made with experiments. Simulated results for E-glass-, graphite-and Kevlar-epoxy type composites showed close agreement with the experiments.

## Abstract In the cryogenic temperature range common lubricants solidify and therefore, they cannot be applied. Thus, for tribosystems in low temperature environment technical solutions based on good dry lubricating properties of the materials themselves must be found. In this concern polymers are
