Impact Energy Evaluation of Natural Castor Oil Polyurethane Matrix Composites Reinforced with Jute Fproduced with variation of layers of fabric between 1 and 6. Subsequently, the energy absorption through the Charpy impact test was evaluated. In Conclusion, it can be emphasized that the fabric, as reinforcement, generates a significant improvement in the properties obtained.
