“…Typical manufacturing methods to fabricate laminates composite parts are vacuum-assisted resin transfer molding (VARTM) [4,22,23], autoclave molding [4], compression molding (including hot pressing) and hand lay-up [22]. A review of some of the techniques for manufacturing of multiscale composite and challenges can be found in the work of McCrary-Dennis and Micah [4].…”

“…Surface treatment of fiber reinforcements with nanoparticles, on the other hand, could improve the in-plane, fiber-dominant properties of laminated composites as well as interfacial adhesion. Some examples of surface treatment are chemical grafting [24,25], electrochemical method [26,27], plasma treatment [28], and sizing method [29,30]. Surface treatment allows for higher loadings of nanoparticles and alleviates the problem of agglomeration commonly observed when nanoparticles are freely dispersed in a matrix.…”

Fiber and matrix‐dominant properties of fiber‐reinforced polymer composites are important in many structural applications. Pre‐mixing the polymer matrix with nanoparticles could enhance the through‐thickness or matrix‐dominant properties. Surface treatment of fiber reinforcements with nanoparticles, on the other hand, could improve the in‐plane or fiber‐dominated properties of laminated composites, as well as interfacial adhesion. In this article, a novel low‐cost manufacturing method, combining surface treatment of fibers with matrix modification techniques, was devised to incorporate nanoparticles for the simultaneous reinforcement of matrix and fibers without increasing the viscosity of the epoxy matrix. Several graphene‐based nanomaterials, including graphene oxide (GO) and its thermally reduced version (rGO), graphene nanoplatelets (GNPs), and multi‐walled carbon nanotubes (MWCNTs) were employed to modify the epoxy matrix and the surface of glass fibers. Unmodified and modified epoxy and fibers were used for fabricating multiscale glass fiber‐reinforced composites following the vacuum‐assisted resin transfer molding process. The composites obtained combined improvements in both the fiber and matrix‐dominant properties, resulting in superior composites. We investigated the morphological, rheological and mechanical properties of the glass fiber‐reinforced multiscale composites. The results from testing for tensile properties and interlaminar shear strength (ILSS) of the glass fiber‐reinforced composites indicate that the introduction of GNPs, GO, rGO, and MWCNTs enhanced mechanical properties. The fracture surfaces of the fiber‐reinforced composites were examined by scanning electron microscopy and we used the micrographs to explain the tensile and ILSS results. POLYM.

“…This correlation was found to accurately predict the simulated interfacial thermal resistance between contiguous GNRs, at least in the geometrical ranges considered. The proposed correlation could be utilized for the bottom-up prediction and optimization of the effective thermal transmittance of graphene nanofiller networks [58]. Future studies should focus on assessing the possible effect of irregular GNR shapes on the R k at the filler-filler interface [59], and determining similar correlations for the R k at the filler-matrix interface taking into account the effect of matrix and filler functionalizations.…”

Heat Transfer at the Interface of Graphene Nanoribbons with Different Relative Orientations and Gaps

et al. 2019

View full text Add to dashboard Cite

Because of their high thermal conductivity, graphene nanoribbons (GNRs) can be employed as fillers to enhance the thermal transfer properties of composite materials, such as polymer-based ones. However, when the filler loading is higher than the geometric percolation threshold, the interfacial thermal resistance between adjacent GNRs may significantly limit the overall thermal transfer through a network of fillers. In this article, reverse non-equilibrium molecular dynamics is used to investigate the impact of the relative orientation (i.e., horizontal and vertical overlap, interplanar spacing and angular displacement) of couples of GNRs on their interfacial thermal resistance. Based on the simulation results, we propose an empirical correlation between the thermal resistance at the interface of adjacent GNRs and their main geometrical parameters, namely the normalized projected overlap and average interplanar spacing. The reported correlation can be beneficial for speeding up bottom-up approaches to the multiscale analysis of the thermal properties of composite materials, particularly when thermally conductive fillers create percolating pathways.

“…Epoxy-based composites have a wide range of applications in various industrial productions such as construction materials, encapsulation resins, metal coatings, electrical components/light emitting diodes (LEDs), high tension electrical insulators, structural adhesives, and more [1][2][3]. However, the poor flame-resistant property of epoxy-based composites severely restricts their applications [4].…”

In this work, functionalized multi-walled carbon nanotubes (MWCNT) were synthesized by the reaction between acylated MWCNT and 10-(2,5-dihydroxyphenyl)-9,10-dihydro-9 -oxa-10-phosphaphenanthrene-10-oxide (ODOPB). The obtained MWCNT-ODOPB was well dispersed into epoxy resins together with aluminum diethylphosphinate (AlPi) to form flame-retardant nanocomposites. The epoxy resin nanocomposite with phosphorus content of 1.00 wt % met UL 94 V-0 rating, exhibited LOI value of 39.5, and had a higher T g compared to neat epoxy resin, which indicates its excellent flame retardant performance. These experimental results indicated that MWCNT-ODOPB was a compatible and efficient flame retardant for epoxy resins. Moreover, cone calorimeter analysis showed that the peak heat release rate (pHRR), total heat release (THR) values, and CO 2 production profiles of the composites decreased with an increase in the additional amount of phosphorus. groups onto outside surfaces of carbon nanotubes further diversifies their functions [15][16][17]. For these reasons, functionalized carbon nanotubes with enhanced dispersibility and interfacial interaction in polymers have been applied as group carriers to improve the performance of polymer matrixes [18][19][20].In this study, DOPO-functionalized multi-walled carbon nanotubes (MWCNT) were synthesized by grafting 10-(2,5-dihydroxyphenyl)-9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (ODOPB) onto the outside surfaces of acylated MWCNT. The functionalized MWCNT was used as an additive together with nano-sized aluminum diethylphosphinate (AlPi) to form fire-resistant epoxy resin composites. The ER/AlPi/MWCNT-ODOPB nanocomposites with 1 wt % phosphorus content exhibited the best UL 94 rating (V-0) and an upgraded limiting oxygen index (LOI) value of 39.5. At the same time, the as-prepared composites also showed higher T g values than neat epoxy resin for a good interaction between epoxy chains and MWCNT-ODOPB. Besides, cone calorimeter tests (CCT) were used to study the fire hazards for MWCNT-ODOPB-modified epoxy resins. The results indicated a clear decrease in a peak heat release rate (pHHR) and a total release rate (TRR) with an increase in the phosphorus content. Furthermore, the CO 2 and CO production during related tests also exhibited the same trend.
