Creep of resins ÉD20 and PN609

Pure creep strain is satisfactorily predicted by a power function of dimensionless time with an exponent smaller than unity.
The slope of the initial linear part of the stress-strain diagram of the binder determines its modulus of elasticity.
The relative elongation of polyester resin upon fracture under conditions of creep is greater than the corresponding elongation in short-term tests.
The viscoelastic characteristics of material obtained in the course of 504 h are suitable for predicting creep within a time almost one order of magnitude longer.
