Huntsman Advanced Structural Composites Business Unit presented a paper at the recent SAMPE exhibition to develop a new RTM system.

The Advanced Materials Structural Group have been actively working in the development of high performance systems for Resin Transfer Molding (RTM) processes for aerospace and industrial composite applications.

A new RTM system based on a novel benzoxazine/epoxy chemistry has been developed and is in the final phase of commercial introduction to the market place. This new system is processable at 177°C using traditional RTM techniques.

The cured composite properties proved to be superior to the traditional epoxy systems. The 177°C cured composite had glass transition (Tg) temperatures in excess of 200°C with excellent thermal mechanical properties. The cured neat resin modulus is also significantly higher than the traditional epoxy systems and in particular, modulus retention under hot wet conditions was shown to be excellent.

This is supported by the fact that benzoxazine chemistry has very low moisture absorption characteristics. The overall composite thermal mechanical properties were shown to be superior and comparable to the high performance prepreg resin systems. The system also displayed superior thermal oxidative stability.

The paper described in detail the chemistry, processing and performance of this system as well as the rational behind the selection of different components and their effect on the overall system properties. Details of neat resin and composite processing and processing kinetics are discussed and are available from the website.
