Flexible thermoset composites have a wide range of applications, particularly in civil construction, interior design and the automotive industry. The main polymer matrices used for lignocellulosic fiber-based composites are epoxy resin, unsaturated polyester, polybenzoxazine and polyurethane. Many of these resins are synthesized from vegetable oils, whose long chain makes polymers flexible, with the most widely used derived from soybean oil. The main tests Applied to demonstrate the flexibility of the composites and resins were dynamic mechanical analysis, thermogravimetry and flexural strength testing.
