Currently the Design, supported by materials engineering, seeks to develop products from renewable and lower impact without harming the environment. The search for energy efficiency measures associated with new materials also boosted researches in the area of polymer composites. The replacement of traditional materials with new materials has being intensified, especially in the last 20 years. This development is related to the possibility of producing composites having good mechanical properties and low density that can even replace materials such as wood and steel. Several natural fibers are produced in almost every country around the world and they are known as lignocellulosic materials. The development of materials from renewable sources, such as natural fibers, is a current reality. Today in the world 30 million tons of natural fibers are produced and Brazil is responsible for a large part of this production. Due to the variety of specimens existing in Brazil, the interest in scientific and technological research has increased with traditional fibers, such as sisal and jute and also with other types of plants such as curaua (Ananas erectifolius). Being the plant that produces fibers with high mechanical resistance, especially when added to polymers, their use in combination with other types of material could result in a tougher product, with low density, good toughness and good thermal properties. Infrared thermography, employed in this research, is a technique of non-destructive testing of wide applicability since it measures the temperature field of a surface from the image generated by the thermal radiation. The inspection process is done by using equipment with detectors sensitive to infrared that capture the thermal radiation and convert it into thermal imaging. In this research was developed a polymer composite based in thermoplastic starch (TPS), low density polyethylene (LDPE) and curaua fiber in the proportion of 10%, 20% and 30% m/m (mass/mass). The developed composite was applied on ceramic blocks and subjected to natural sunlight. Its thermal behavior was monitored using infrared thermography. The results show that the composites manufactured have potential for use as thermal insulated element in buildings. Thermography was effective for identifying
