This is due to their complex structure, in which the small building blocks of the hard component are embedded in a softer matrix, thus combining strength and toughness. This combination makes such materials interesting for various applications, e.g. for tooth replacement materials but also for industrial structural materials. Therefore, the interest is to develop scalable processes for the production of artificial composites. In this work a Nano Spray Dryer is used to produce polymer-encapsulated magnetite particles from a magnetite-polymer-suspension. A Design of Experiment study is conducted which identified the suspension composition as the major influencing factor on the product properties. The particles are then warm-compacted and the composite pellets are examined for their mechanical properties and structure. With this method composites with bending strength of 91.2 MPa and Young's modulus of 9.2 GPa were produced.en0032-59102021394402Mechanical properties of compositesNano spray dryerParticle encapsulationPolymer-matrix compositesAllgemeines, WissenschaftJournal Article10.1016/j.powtec.2021.08.063Other
