Detailed description of the research.

The relative dimensional change (ΔL/L0) versus temperature was measured up to 1300 °C under flowing argon with a 5 °C/min heating rate using a dilatometer Netzsch mod. DIL E 402 (Netzsch, Geraetebau, Germany), on 25 mm x 2.5 mm x 2 mm bars

Self-reinforced polymer composites (SPCs), also called “single polymer composites” or “all-polymer composites”, have attracted the attention of academia and industry because of the strong fiber/matrix adhesion, reduced weight, and enhanced recyclability. However, their mechanical properties are usually limited. The incorporation of nanoparticles to enhance the properties of SPCs has become an issue of concern. No study to date has investigated the incorporation of graphene into SPCs. The film stacking technology of SPCs and nanotechnology of graphene were combined to produce graphene-reinforced polypropylene (PP) SPCs with enhanced mechanical properties. The incorporation of a small number of graphene platelets (GNPs) to produce PP/GNPs SPCs has been presented. The small number of GNPs will not increase the cost a lot but can improve the processing as well as the mechanical performance of the final product. For PP/GNPs SPCs, the addition of only 0.062 wt% of GNPs resulted in an increase in the tensile strength and modulus of 117% and 116%, respectively, as compared with values of pure PP. Compared with PP SPCs without graphene, a 42% increase in the tensile strength was achieved. The improvement of mechanical properties of PP/GNPs SPCs is attributed to the high intrinsic mechanical properties of GNPs, the self-reinforced mechanism of PP SPCs, and the stronger interfacial adhesion between fibers due to the superior thermal conductivity of GNPs. The 116% increase in interfacial strength clearly proved the benefits of the incorporation of graphene in the preparation of SPCs.

The present dataset includes an addendum to the main paper presenting additional information about the additive manufacturing of the physical models of fractal fibers and meshes, laser scanner surveys, and contact angle tests. The STL models of all the reinforcing elements analyzed in the present study are also given as individual files.

This dataset provides a summary of software for topology optimization and lattice generation used in design for additive manufacturing to-date and represents supplementary information to the review article: Review on design and structural optimisation in additive manufacturing: Towards next-generation lightweight structures employing material isotropy.
