“…The presence of CNF agglomerates in the specimen having 0.5 wt% f‐CNF, as indicated in the next section, can mainly be responsible for this reduction. The increased viscosity of the resin at the higher f‐CNF loading (i.e., 0.5 wt%) and the improper dispersion of CNF lead to an inappropriate wetting of basalt fiber with the nanocomposite matrix, creating a poor interfacial bonding …”

This work focuses on the preparation and characterization of multiscale epoxymatrix composites reinforced by basalt fibers and carbon nanofiber (CNF). CNF powders were first functionalized with 3-aminopropyltrimethoxysilane and characterized by Fourier-transform infrared spectroscopy, and thermogravimetric analysis; then, the epoxy resin was incorporated with 0.05 wt%, 0.1 wt%, 0.3 wt%, and 0.5 wt% f-CNF. The influence of functionalized-CNF (f-CNF) loading on the interlaminar shear strength (ILSS), tensile, and wear behaviors of the multiscale basalt fiber/epoxy composites was studied. Whereas a relatively small improvement (12%) in tensile strength was achieved, a remarkable enhancement in ILSS (73%) was obtained for the multiscale specimen with an f-CNF loading of 0.3 wt%. Also, the multiscale specimen filled with 0.5 wt% f-CNF showed an improvement of 37% in tensile modulus. The wear rate and friction coefficient of the 0.3 wt% f-CNF loaded composite were decreased by 56% and 38% with respect to the neat specimen, respectively. To establish the microstructure-property relationship, the worn and fractured surfaces of the specimens were analyzed.

Constructing a hierarchical structure of nanomaterials on the surface of reinforcing fibers is the best strategy to obtain other desired functions while improving the mechanical properties of polymers. In this article, acid-treated multiwall carbon nanotubes (MWCNTs) were introduced to the surface of milled glass fiber (MGF) under the combined action of tetraethyl orthosilicate and 3-aminopropyltriethyloxysilane to prepare a hierarchical fiber (MWCNTs-GF). The surface morphology and microstructure of this hierarchical fiber were characterized by field-emission scanning electron microscope and transmission electron microscope, and a composite coating with MWCNTs as the main component was observed on each fiber surface. Fourier transform infrared and Raman spectroscopy revealed the presence of the specific interactions between MWCNTs and MGF. Polyamide 66 (PA66) composites with different content of MWCNTs-GF were fabricated by melt blending. The resulting composites exhibited improved mechanical properties relative to pure PA66, in which the tensile strength and notched impact strength of the composite filled with 3 wt% MWCNTs-GF increased by 23.3% and 69.0%, respectively. Subsequently, by analyzing fracture morphology and interfacial adhesion of the composites, the strengthening and toughening mechanisms of MWCNTs-GF were elaborated in detail. In addition, the results of thermogravimetric analysis and differential scanning calorimetry showed that MWCNTs-GF possessed strong heterogeneous nucleation ability, and its addition could refine the grain size of PA66 and significantly increase the crystallization temperature and thermal stability of the corresponding composites. Compared to PA66 composites reinforced with neat MGF, it was found that the unique surface structure of MWCNTs-GF was likely responsible for improved thermal properties of this hierarchical fiber-reinforced PA66 composites.

An economical and effective method was developed to optimize the interface of glass fiber fabric (GFf)-reinforced epoxy composites (GFfE) by dispersing aminosilane-functionalized graphene oxide (GO) on the fiber surface. The effects of γ-aminopropyltrimethoxysilane (APS) or APS hydrolysis on the dispersion of GO and the interfacial properties of resultant composites were investigated in detail. The results indicated that the uniform dispersion of GO in composites and strong fiber/matrix adhesion could be achieved, based on grafting of APS hydrolysis onto GO. The interlaminar shear, flexural and tensile strengths of resultant composites were improved by 28%, 22% and 19%, respectively; the storage modulus and dynamic glass transition temperature (1 Hz) were significantly enhanced, compared with pure GFfE. In particular, the work of fracture received from interlaminar load–deflection curves increased by 97%, indicating the toughening effect of GO. This work demonstrates that it is possible to enhance the strength, stiffness and toughness of fiber-reinforced composites by incorporating GO into the interface between the fiber and the matrix.
