Market Opportunity

Resin transfer molding (RTM) allows for the production of high quality aerospace and automotive components without the need for expensive and time-consuming autoclave processing. Currently, choice of RTM resins is restricted to formulations that release minimal quantities of volatiles during the cure period, because volatile evolution results in porosity, which limits the strength of the final product. While newer resins such as benzoxazine offer superior mechanical and thermal performance, they release significantly higher levels of volatiles, such as ethyl acetate and water, making their application to RTM impractical. Therefore there is a need for a high quality resin with low cure-volatility for use in RTM.

USC Solution

USC researchers have developed a technique to reduce the amount of volatiles in high quality resins. By reducing the amount of volatiles, high quality resins such as benzoxazine and epoxy resins can be used in RTM enabling the production of high quality aircraft and automotive components.

Value Proposition

  • Reduce volatiles in resins
  • Enables use of broad range of resins in RTM
  • Enables production of high quality components

Applications

  • Resin Transfer Molding

Stage of Development

  • Tested in small scale RTM
  • Available for exclusive and non-exclusive license
