Effect of Silane Modified E-glass Fibre/Iron(III)Oxide Reinforcements on UP Blended Epoxy Resin Hybrid Composite

In this current effort a study was made on UP blended epoxy thermosetting polymer and their properties when amino-silane treated e-glass fibre and iron(III)oxide particles were reinforced. The primary goal of this work is to toughen the brittle epoxy resin by blending low strength unsaturated polyester resin. Blending of low strength polyester reduced the brittleness of epoxy with inferior in some mechanical and thermal properties; hence silane treated e-glass fibre and iron(III)oxide particles was reinforced with UP/epoxy polymer blend to improve thermal and mechanical properties. Particle size of 200 nm and glass fibre of 600 g/m(2) was used as reinforcements. Fibres and particles were surface treated by an amino silane (APTMS). Usefulness of particles and fibres addition was unveiled by mechanical, thermal, and dielectric properties. The reduced mechanical properties were increased when e-glass fibre and iron(III)oxide filler was reinforced. Glass transition temperature and degradation stability was less for UP/epoxy systems than pure epoxy whereas addition of filler increased Tg and degradation stability. The dielectric results showed increased dielectric constant and loss for UP blended epoxy composite.
