Lignocellulosic fibers have been applied to composite materials in order to enhance their mechanical characteristics. Although their economic and environmental benefits have been proven, it is known that these materials can differ in their properties depending on local characteristics of the natural fibers. This study aims to evaluate the variability of the mechanical properties of pineapple leaf fibers (PALFs) from Brazil, India and Malaysia. It was found that pineapple fibers from the same species and region vary in mechanical properties. The species Cosomus cultivated in India presented a variation of 59% in tensile strength. Better mechanical behavior of PALFs was observed with an increase of cellulose crystallinity index. In order to define the best application for PALFs in composites it is necessary to evaluate the specific structural characteristics of each species, once their morphological characteristics depend on local planting conditions.
