Strength Characteristics of Polymer Particle Composites with Filler on the Basis of Waste from Mechanical Surface Treatment

Particle composites are materials reinforcement of which is formed by non fibrous particles. The particle size is in all directions equal. The properties of polymeric particle composites are defined by the synergic sum of the matrix properties and the filler properties. The polymeric particle composite, the filler of which was the waste in form of sawdust, chips and grit blasted material coming from the surface mechanical treatment processes and the matrix was the two-component epoxy adhesive, was the subject of the carried out experiments. The substitution of the primary raw material by the secondary one offers the possibility of the waste thrifty recycling. This possibility should be preferred because the material produced in this way is more economical and more environmentally friendly. The aim of the experiments was to determine the tensile properties of the composites, concretely the dependence between the filler volume in the matrix, and the tensile strength or the tensile lap-shear strength of bonded assemblies. These materials can be applied mostly in renewal of mechanical parts and in the fields of bonding and puttying. The potential areas of application in agriculture are the renovations of soil processing tools.
