“…This opens up new areas of application as energy absorbers for mechanically oscillating or impact related tensions and loads, for example areas of damping aid for swinging masses or personal protection as a shielding component of projectiles or in an industrial environment. However, the production of geometrically complex components is expensive [1,2]. The solution is a combination of C/C composites with a thermoplastic, like an ethylene-vinylacetate-copolymer (EVA).…”

“…In addition, the costs can be reduced, by means of a targeted application of the expensive C/C composite into smart produced ceramic/polymer material compound. As a result of these advances new areas of application are revealed, for example as wear and tear resistant and chemically inert energy absorbing parts or medical applications [1][2][3]. In order to develop these innovative hybrid material compounds with improved porous properties, further basic investigations and studies concerning C/C composites are required.…”

Carbon fibre reinforced carbon composites (C/C) are characterised by their excellent thermal, chemical and mechanical properties. The intrinsic porosity and fibre reinforcement grant them an excellent damage tolerance. The production of complex structures is time consuming and very expensive. An innovative approach to this topic is the integration of simple geometric ceramic composite materials within complex polymer structures. The motivation of this contribution is to investigate the influence of hexamethylenetetramine as hardener (hardener content: 4, 8, 12 and 16 %) and curing parameters (tempered and non-tempered) on the microstructure and mechanical properties of the porous C/C composites. During the course of this contribution, selected carbon fibre reinforced polymer (CFRP) composites with different porosities were produced while adjusting the resin or hardening agent-ratio, as well as the processing parameters. Subsequent to the curing of the CFRP samples, porous C/C composites were produced by means of a pyrolysis process. The final part of the contribution is comprised of the microstructural analysis by light microscopy and the explanation of the flexural strengths, by utilising a “three-point-bending test”.
