ABSTRACT
The use of lignocellulosic fibers as reinforcement in polymeric matrices has become an interesting procedure for developing biocomposites with the possibilities of use in the automotive sector, in construction and the field of packaging, among other applications. In this sense, for the development of these biocomposites, matrices based on synthetic polymers derived from petroleum have conventionally been used; however, in recent years, the use of biodegradable polymers, either synthetic or from natural sources (mainly agro-polymers or polymers of microbial origin), has been encouraged in order to prepare true biobased composites. For the structural analysis of these biocomposites, Dynamic Mechanical Analysis (DMA) is an important characterization technique that allows identifying the influence of parameters such as the nature of the matrix, the presence of additives, the type and quantity of the fibers, the superficial modification of the fibers, among others, on the mechanical properties of the biocomposites as a function of temperature. Due to the importance mentioned above, this part will describe the behavior of different types of biocomposites, emphasizing the effect of various design parameters on their mechanical properties.
