The structure, generalised parameters, and rheological properties of epoxy spheroplastics

摘要

An investigation was made and a description given of the rheological properties of spheroplastics based on hollow glass microspheres and epoxy oligomers in generalised parameters of their particulate-filled structure. It is shown that the main generalised parameters of the particulate-filled structure, determining the viscosity and fluidity limit, are the parameters a_(av) and Θ, which depend on the packing of particles and their content in the composite. Dependences of viscosity and fluidity limit of particulate-filled polymer composites in generalised parameter coordinates are given for the first time, and the spheroplastics are classified according to the structural principle.
