Relaxation characteristics of reinforced plastics in tension of ring specimens by split disks

  • Published:
Mechanics of Composite Materials Aims and scope

The behavior of organic- and carbon-fiber-reinforced plastics based on three different binders was investigated under three test modes: stress relaxation, strain relaxation, and creep. In the theory used, the linearized generalized Maxwell–Gurevitch equation is employed. From stress relaxation diagrams, the relaxation constants of the equation are determined, which are utilized for calculating creep diagrams. The elastic and strength characteristics of the composites are also investigated.

Notes

  1. ECD is a polyglycidyl derivative of the aromatic amine 3,3´-dichlor-4,4´-diaminodiphenylmethane, containing 27-30% epoxy groups, 5-6% nitrogen, and 12-15% chlorine, cured by isomethyltetrahydrophthalic anhydride (MTHPA) or diaminodiphenylsulfone (DADPS) [3]. Rolivsan MV-1 is a liquid monomer-oligomer composition obtained in a chemical way.
