Mechanical and dielectric evaluation of glass fibre reinforced Epoxy-Cyanate composites Brahmbhatt Priyanka1, Pradhan Subrata1 1Institute for Plasma Research, Bhat, Gandhinagar, India Abstract The insulation system for the magnet winding pack is a fibre reinforced plastic (FRP) laminate, which consists of a S-glass fibre reinforcement tape, vaccum impregnated with epoxy-cyanate blend system, in order to evaluate the mechanical behavior of composites, different proportion of epoxy-cyanate blends were prepared to impregnate glass fibres. The insulation laminates were irradiated at room temperature using Am-Be source up to fast neutron fiuence of 2.38 × 1012 n/m2 (E>0.1MeV) to investigate the radiation induced degration in mechanical strength of the insulation system. The short beam shear tests and ultimate tensile tests (as per ASTM standards) were performed at room temperature on the composites prior to and after irradiation to evaluate the inter-laminar shear strength and ultimate tensile strength of the composites. The objective of this paper is to evaluate the mechanical and dielectric properties of the glass fiber reinforced epoxy-cyanates composites without using kapton. Top Keywords Epoxy, Cyanate ester, Ultimate tensile strength, Composite. Top | | | |
