Material Utilization of Waste Originating during Processing of Plant Jatropha Curcas L. in Biocomposites – Adhesive-cohesive Characteristics and Wear

Original scientific paper Renewable sources should be preferred by a modern society and this should be done not only in the areas of material engineering. Jatropha curcas L. is a plant with a high potential with many technologically utilized parts among which seeds most of all. The seeds of the plant serve for the pressing of oil. During this technological process worse utilizable commodities such as pressed cakes, seed shells or pressed seed kernels are gained except for primary commodities (oil). A meaningful utilization of these secondary biocommodities is the key for optimization of the whole technological process. An experiment describes mechanical properties of an epoxy resin filled with commodities from the pressing of Jatropha curcas L. treated by the mechanical milling. The epoxy resin (Glue Epox Rapid) filled with microparticles of shells (67,8 μm), of seed cakes (108,1 μm) and of seed kernel cakes (82,7 μm) was used in the experiment.
