Abstract
This work was aimed on improving the toughness of phenolic resin using liquid rubber, Hydroxyl terminated Polybutadiene (HTPB) for aerospace & commercial application. HTPB being chemically inert with Novolac, was blended with Resole. 80/20 blend of Novolac and Resole was selected for toughness improvement studies taking in to account the blend's processability and glass transition temperature.This blend was modified with in different weight fractions of HTPB elastomer. Toughness was studied both in bulk phenolic castings and in woven-glass fabric reinforced composites. Optimum modifier content that gives the maximum improvement in toughness was first identified using bulk phenolic cast SEN-3PB specimens.
