Impact Energy Evaluation of Natural Castor Oil Polyurethane Matrix Composites Reinforced with Jute Fabric

摘要

Motivated by the increasing concern with environmental problems, society and industry are investing materials that are ecologically friends, low-cost, and responsive to the applications they will be subjected to. In this context, the use of natural resins and the use of vegetable-based fibers are an alternative to solving these market requirements by replacing high-cost, non-organic synthetic materials with eco-friendly products. Thus, the objective of this work is to evaluate the properties of a natural matrix, produced with polyurethane based on castor oil and reinforced with jute fabric. Firstly, in order to characterize the fabric, the density of the jute was determined and the spacing between the wefts was analyzed. The materials were produced 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.
