Matrix resin for composite application EPY PEEKTOH

 

Indian Space Research Organization at its Vikram Sarabhai Space Centre (VSSC) has developed EPY PEEKTOH resin which is an elevated temperature curing high performance epoxy resin matrix suitable for composite applications. The specialty of the formulation is good mechanical properties, high glass transition temperature and low outgassing properties. This is an ideal matrix resin for processing thick carbon fabric laminates (= 30 mm) without any micro cracks and delamination.

Salient features are:

• Elevated temperature curing

• Very good mechanical properties

• High glass transition temperature

• Low outgassing properties

• Suitable viscosity at 60-70°C for processing two dimensional fabric laminates
