“…Under quasi-static conditions, for tensile tests the effect of the improved strength is negligible. Likewise, a similar result is presented in [30]. The same result was found for the in-plane shear test, at least under the studied strain range, where the matrix behavior had a major role (see, for example, the explanation presented in [31]).…”

This work investigates the effect of multiwall carbon nanotubes (MWCNTs) on the mechanical and tribological behavior of a fiber reinforced composite (FRC). Fiber reinforced composites and nano-engineered FRCs are manufactured by resin transfer molding. In-plane tensile tests, in-plane shear tests and through-thickness compression tests are used to assess the influence of MWCNTs on the material mechanical behavior. Pin on disk dry sliding tests are used to quantify the effect of MWCNTs on the friction coefficient and the specific wear rate. It was determined that (1) MWCNTs have an influence on the improvement on both the through-thickness compression strength and the specific wear rate, and (2) they do not influence the material stiffness, in-plane tensile and shear strengths and the friction coefficient. It is assumed that the observed improvements are due to the demonstrated positive influence of the MWCNTs effect on the matrix/reinforcement interfacial strength and on the matrix fracture toughness.

“…Highly concentrated CNT/resin mixtures (masterbatches) are nowadays widely used both at laboratory and industrial scales to facilitate the processing of nanocomposite materials [26][27][28]. Although the increased viscosity of the CNT masterbatch can limit diffusion and sedimentation of CNTs by restricting the Brownian motions, reduced distances between the nanotubes at high loadings can give rise to the strong attractive forces, leading to further agglomeration of CNTs during sufficiently long storage periods.…”

Abstract. The state of carbon nanotube (CNT) dispersion in epoxy is likely to change in the process of composite production. In the present work CNT dispersion is characterized at different stages of nanocomposite preparation: in the original masterbatch with high CNT concentration, after masterbatch dilution, in the process of curing and in the final nanocomposite. The evaluation techniques included dynamic rheological analysis of the liquid phases, optical, environmental and charge contrast scanning electron microscopy, electrochemical impedance spectroscopy and dynamic mechanical analysis. The evolution of the CNT dispersion was assessed for two CNT/epoxy systems with distinctly different dispersion states induced by different storage time. Strong interactions between CNT clusters were revealed in the masterbatch with a longer storage time. Upon curing CNT clusters in this material formed a network-like structure. This network enhanced the elastic behaviour and specific conductivity of the resulting nanocomposite, leading to a partial electrical percolation after curing.

“…Some attempts have been made to take this advantage of nanoparticle reinforced matrix to enhance the mechanical performance of fiber composites [8,[14][15][16]. Many published studies extensively focused on tensile properties, fracture toughness, and interfacial strength of carbon fiber composite [17][18][19][20][21] with modified matrices using nanoparticles. Only a limited number of studies were conducted to investigate the influence of nanoparticles on the compressive and flexural properties of fiber/epoxy composites, particularly, for the composites prepared by RTM and VARIM.…”

Compressive properties are commonly weak parts in structural application of fiber composites. Matrix modification may provide an effective way to improve compressive performance of the composites. In this work, the compressive property of epoxies (usually as matrices of fiber composites) modified by different types of nanoparticles was firstly investigated for the following study on the compressive property of carbon fiber reinforced epoxy composites. Carbon fiber/epoxy composites were fabricated by vacuum assisted resin infusion molding (VARIM) technique using stitched unidirectional carbon fabrics, with the matrices modified with nanosilica, halloysite, and liquid rubber. Testing results showed that the effect of different particle contents on the compressive property of fiber/epoxy composites was more obvious than that in epoxies. Both the compressive and flexural results showed that rigid nanoparticles (nanosilica and halloysite) have evident strengthening effects on the compression and flexural responses of the carbon fiber composite laminates fabricated from fabrics.
