The observed effect of a reduced mechanical performance with increasing testing volume in pure supercrystalline materials only allows to evaluate these materials via micromechnical tests, since the macroscopic fracture behavior is dominated by preexisting flaws, as previously mentioned. In contrast, the improved robustness of the infiltrated epoxy resin materials enables further macroscopic mechanical characterizations. Hence, 2HL composite samples were cut into 1.2×1.2×10 mm bars and tested under 3-point-bending . The chosen topology of the epoxy leads to a soft, plastically deforming polymer resin with a flexural modulus, E flex , of 0.6 ± 0.1 GPa, ultimate strength of 35 ± 2 MPa, and a yield point at 5.0 % strain.
