  • Data for: The incorporation of graphene to enhance mechanical properties of polypropylene self-reinforced polymer composites
    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.

  • Data for: Fused filament fabrication of functionally graded polymer composites with variable relative permittivity for microwave devices
    Fused filament fabrication (FFF) is a continuously growing additive manufacturing technology that aside from physical prototypes can also deliver functional prototypes and devices for radiofrequency (RF) and microwave applications. The very recent introduction of high-permittivity filaments for FFF has been one of the main facilitators for this major advancement, aiding microwave engineers to realise academics concepts that have thus far been impossible to fabricate and therefore invent new designs. However, the value to the RF community of these devices depends on accurate knowledge and repeatability of the electromagnetic properties of the materials being used which strongly relies on the processing strategy used during printing. This paper investigates the use of a high-permittivity filament and studies the impact of layer height and infill density on the relative permittivity (εr) and loss tangent (tanδ). A maximum relative permittivity of εr = 9.63 ± 0.16 and tanδ = 0.003 ± 0.0003 was achieved with a 200 μm layer thickness and 100% infill density. Finally, the results of this study are used in designing, simulating, 3D printing and measuring the performance of a novel graded-index dielectric lens operating at 10 GHz.

  • Data for: Highly thermally conductive polybenzoxazine composites based on boron nitride flakes deposited with Copper particles
    The reaction heat decreased with the increase of BN@2Cu hybrid fillers The onset of polymerization exotherm (T0), the peak temperature (Tp) both increased sharply with the introduction of hybrid fillers while T0 and Tp showed little dependence on filler loading.

  • Data for: Highly thermally conductive polybenzoxazine composites based on boron nitride flakes deposited with Copper particles
    The Cu particles (CuPs) can be clearly observed on the surface of BN flakes without aggregation. The CuPs are speculated to be mainly attached onto the defect sites and the active edges of BN covered with some functional groups such as hydroxyl groups and amino groups
