Abstract:
Synopsis:
This paper describes the tensile creep behaviour of fibre reinforced
plastics under a uniaxial stress system. In particular, unidirectionally
and bidirectionally reinforced plastics are considered for the relative
ease with which samples of them can be manufactured.
A composite model that has previously been described 1, 2 is used as
the basis of theoretical predictions of the variation of the creep
compliance with certain material parameters. The parameters whose
effects are examined are the volume fraction of the fibres, the distribution
of fibre orientations, and the angle between a specified direction and
the direction of application of a uniaxial stress system.
Specimen experimental results are included to show the accuracy
of these predictions and any shortcomings of the theoretical model are
examined in the light of this comparison.
