Composite materials are becoming more important for aerospace industry and parts made with fiber reinforced plastics (FRP) comprise over 50 % of a modern civil aircraft mass. Whilst thermal stability of FRP allows their application for wings and body construction, turbines of engines are mostly made from metals. Thermal stability of FRP is limited by the polymer matrix while inorganic fibers possess much higher thermal stability. Recently it has been reported that propargyl aryl ether blended with phthalonitriles could act as a polymerization activator of the latter, forming materials with high thermal properties inherent to phthalonitrile matrices [1]. Based upon these results, in this work we combined propargyl ether and phthalonitrile function in one molecule acquiring in new bifunctional self-curing monomers suitable for acting as matrices for CFRP.
