Abstract

Phthalonitrile resins have potential to be used over 300oC and own excellent high-temperature properties and superior mechanical properties. However, the resins have some disadvantages due to the high-melting temperature of phthalontrile monomers. In order to improve the processability of phthalontrile resins without sacrificing their thermal properties, a novel resin system with good tack at room temperature was developed due to the blends of the reacted diluents 3-aminophenylacetylene and phthalontrile monomer. The thermal and mechanical properties of the obtained phthalontrile resin system and the corresponding fiber reinforced imprepreg&composites were studied. Results showed that the phthalontrile had high temperature (Tg=420oC) and comparable properties with commercial PMR-15 Polyimide.

About the presenter

Chengyuan Shang is an associate professor and senior engineer with the Aerospace Research Institute of Materials & Processing Technology, Beijing, China, whose main study is concentrated on the matrix resin for advanced composites, including thermosetting resin toughening, bismaleimide resin and phthalontrile resin with high- temperature resistance.
