“…Important use of epoxy resin is polymer matrix of fiber‐reinforced plastic (FRP), which is a composite material consisting of synthetic polymers and fibers. Fiber‐reinforced plastics (FRPs) are commercially used in the aerospace and automotive industries, civil construction, and sports equipment . In these applications, mechanical properties of the products are controlled by the interfacial interactions between the adhesive and the surface of adherend material.…”

Molecular understanding of the adhesive interactions between silica surface and epoxy resin: Effects of interfacial water

The molecular mechanism of the adhesion between silica surface and epoxy resin under atmospheric conditions is investigated by periodic density‐functional‐theory (DFT) calculations. Slab models of the adhesion interface were built by integrating a fragment of epoxy resin and hydroxylated (0 0 1) surface of α‐cristobalite in the presence of adsorbed water molecules. Effects of adsorbed water on the adhesion interaction are evaluated on the basis of geometry‐optimized structures, adhesion energies, and forces. Calculated results demonstrate that adsorbed water molecules significantly reduce both the adhesion energies and forces of the silica surface–epoxy resin interface. The reduction of adhesion properties can be associated with structural deformation of water molecules confined in the tight space between the adhesive and adherend as well as structural flexibility of the hydrogen‐bonding network in the interfacial region during detachment of the epoxy resin from the hydrophilic silica surface. © 2018 Wiley Periodicals, Inc.

“…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 , electrochemical method , plasma treatment , and sizing method . Surface treatment allows for higher loadings of nanoparticles and alleviates the problem of agglomeration commonly observed when nanoparticles are freely dispersed in a matrix.…”

Simultaneous reinforcement of matrix and fibers for enhancement of mechanical properties of graphene‐modified laminated composites

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.

Improving the interfacial adhesion is indispensable for carbon fiber (CF) reinforced polyamide (PA) composites. An external emulsion sizing agent based on epoxy resin and an anionic self‐emulsifying sizing agent by introducing p‐aminobenzoic acid (PABA) into epoxy resin and neutralizing with triethanolamine were prepared, respectively. It was found that the self‐emulsifying agent showed the benefit on reducing the hairiness of CF, which was pronouncedly decreased from 47.4 to 7.7 mg. The tensile strength of corresponding PA composite was improved from 148.3 to 186.3 MPa, while the notched impact strength was increased from 7.7 to 13.7 KN/m2, compared with that of unsized CF reinforced composite. The self‐emulsifying sizing agent exhibited higher interfacial adhesion between CF and PA matrix than the external emulsion, due to the hydrogen bond between the NH group in PABA and CO group in PA. The combination of physical adsorption and chemical bond of the self‐emulsifying sizing agent resulted in the improvement of mechanical properties. POLYM.
