Mechanical properties of hybrid polyester composites

There are different reasons why the production of polyester composites with natural reinforcements, like jute can be of interest. One of them is to fabricate the hybrid composites with cheap waste jute sacks as reinforcements in combination with glass mat. The laminates have been fabricated with a different number of jute and glass mat layers and different type of polyester resins. Also, the content of cross-linking agent has been varied. As the indicator of change of mechanical properties, tensile and flexural strength as well as tensile and flexural modulus have been determined. Based on the planned experiments and statistical analysis it can be concluded that in comparison with glass mat polyester composites, the mechanical properties of hybrid composites in optimal combination of glass and jute reinforcements are lower, but at the same time the laminates are 15 to 20% cheaper.
