TL;DR: In this paper, a review of recent progress in the mechanical, thermal and interfacial properties of graphene/CNT multiphase polymer composites is examined, highlighting the improvements in two-and three-phase composites, owing to the addition of graphene and CNT.
Abstract: In this review, recent progress in the mechanical, thermal and interfacial properties of graphene/CNT multiphase polymer composites is examined. Progress in the mechanical and thermal properties of CNT (1D) and graphene (2D) nanostructure materials is also reviewed and compared. Furthermore, this review highlights the improvements in the mechanical, thermal and interfacial properties of two- and three-phase composites, owing to the addition of graphene/CNT. In particular, analysis of several notable papers on hybrid composites (graphene/CNT) provides an intensive review of synergetic effects on the overall properties of the corresponding composites. This holistic review describes an improved interface between fibers and a nanofiller-reinforced matrix. Although the presence of nanofillers even at low loadings confers an overall improvement in composite properties, the exact ratios of individual fillers and combined forms remain to be discussed in depth. Finally, potential applications, current challenges and future perspectives for use of these multiphase composites are discussed with regard to their extraordinary capabilities and promising developments in graphene/CNT family-based composite materials.

TL;DR: In this article, the authors reviewed polymer and cement composites reinforced with basalt fibers and discussed strategies for improving the fiber-matrix interface, such as surface modification of the fibers and the addition of micro-and nanofillers to the matrix.
Abstract: Basalt fibers (BFs) have attracted much attention in the composites industry because they are chemically stable and have excellent mechanical and thermal properties. Due to their high commercial value, BFs have many applications in the polymer and construction industries. Although BF dosage is a key factor in basalt-fiber-reinforced composites (BFRCs), and mechanical performance improves significantly as the dosage increases, the fiber–matrix interface is another important parameter that determines the performance of BFRCs during their service life. The adhesion between the matrix and the BF is crucial for transferring stress and enhancing the mechanical properties of the composite. This paper reviews polymer and cement composites reinforced with BF and discusses strategies for improving the fiber–matrix interface, such as surface modification of the fibers and the addition of micro- and nanofillers to the matrix.

TL;DR: In this paper, the effect of environmental temperature on the mechanical response of glass fibre/epoxy (GE) composite loaded with a range of graphene oxide (GO) content was investigated.
Abstract: The unique and exceptional properties of graphene based nanofillers have impelled material scientists for their possible exploitation in fibrous polymeric composites. Present investigation elucidates the effect of environmental temperature on the mechanical response of glass fibre/epoxy (GE) composite loaded with a range of graphene oxide (GO) content. Incorporation of 0.5 wt.% GO in GE exhibited 21.1% improvement in flexural strength. The state of interface (both GO/epoxy and glass fibre/epoxy) and its impact on the flexural behaviour at various testing temperatures has been discussed. The viscoelastic properties of all the materials have been further evaluated in the temperature range of 40–200 °C. The Weibull design parameters have been analysed as a function of GO content and testing temperature. Scanning electron microscope (SEM) analysis of fractured surfaces has been carried out to comprehend various interfacial strengthening and failure micro-mechanisms.
