Matrix resin for composite application EPY PEEKTOH



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.

The processing involves incorporation of selected quality fillers and ingredients in specific type of silicone polymer resin and use of suitable curatives to achieve desired thermo-physical properties.
