N Prasanaa Iyer, N. Arunkumar
Abstract
Bismaleimide (BMI) is a high performance thermoset material which possess similar characteristics as that of Polyimides which include high strength and rigidity at high temperature. It can be used for high temperature application upto 260° C. It stands between epoxy and polyimide in its thermal stability and moisture absorption properties. The resin is brittle in nature which necessitated modification with various modifiers viz epoxy, phenol Novolac, Polydimethylsiloxane (PDMS), Allyl phenol, Amines, Carbon nanotubes(CNT), ceramic materials etc. at chemical level to reduce its brittleness. The bismaleimide is used as a matrix in composite materials is reinforced with fibers viz carbon, Kevlar, Basalt, glass fibers. Various authors studied the bismaleimide composite material for its application in Aircraft and missile structures which requires thermal stability and high strength at high temperature. is the resin. In this article the fiber reinforced modified bisamleimide resin composite materials are reviewed with an intend to explore the wide application of the resin system.
