Fracture Behaviors of TRGO-Filled Epoxy Nanocomposites with Different Dispersion/Interface Levels
In this work, we investigate mechanical properties and fracture behaviors of thermally
reduced graphene oxide (TRGO)-filled epoxy composites with two different dispersion/
interface levels. The amphiphilic surfactant treatment of TRGO was found to promote the
dispersion in both water and epoxy, but also produced improved TRGO/epoxy interface. As
expected, incorporation of untre...

006. Competitive absorption of epoxy monomers on carbon nanotube: a molecular simulation study
Position restrained (PR) molecular dynamics (MD) simulations were carried out on the bulk models for the two composite systems including epoxy monomers and carbon nanotube (CNT). The pair energies and the radial distribution functions (RDFs) were computed to evaluate the relative strength of the epoxy monomers binding to the CNT. It is found that the aromatic amine ...

003. Atomistic molecular simulations of structure and dynamics of crosslinked epoxy resin
Many excellent thermal and mechanical performances of cured epoxy resin products can be related to their specific network structure. In this work, a typical crosslinked epoxy resin was investigated using detailed molecular dynamics (MD) simulations, in a wide temperature range from 250 K to 600 K. A general constant-NPT MD procedure widely used for linear polymers failed to identify th...

Bioinspired Highly Electrically Conductive Graphene-Epoxy Layered Composites
Inspired by the nano/micro-scale hierarchical structure of nacre, we developed a new method for fabricating highly electrically conductive graphene-epoxy layered composites. In this new method, the graphene loading can be easily controlled, and the intrinsic three-dimensional (3-D) network of graphene in the composites results in high electrical conductivity. Through effective surface modification...

Thermal conductivity epoxy resin composites filled with boron nitride
Boron nitride (BN) micro particles modified by silane coupling agent, γ-aminopropyl triethoxy silane (KH550), are employed to prepare BN/epoxy resin (EP) thermal conductivity composites. The thermal conductivity coefficient of the composites with 60% mass fraction of modified BN is 1.052?W/mK, five times higher than that of native EP (0.202?W/mK). The mechanical properties of the composites are...

Mechanical properties of epoxy composites filled with silane-functionalized graphene oxide
In this work, the effects of as-produced GO and silane functionalized GO (silane-f-GO) loading and silane
functionalization on the mechanical properties of epoxy composites are investigated and compared. Such
silane functionalization containing epoxy ended-groups is found to effectively improve the compatibility
between the silane-f-GO and the epoxy matrix. Increased storage modulus,...

Mechanical properties and fracture behaviors of epoxy composites with multi-scale rubber particles
In this work, we developed a strategy to balance the toughness and thermal resistance of epoxy composites by incorporating the multi-scale rubber particles. Two types of rubber i.e. the phase-separationformed submicron liquid rubber (LR) and preformed nano-scale powered rubber (PR) particles were chosen as tougheners. It was found that the combination of these multi-scale rubber particles not...

The effect of graphene dispersion on the mechanical properties of graphene/epoxy composite
The effect of dispersion state of graphene on mechanical properties of graphene/epoxy composites was investigated. The graphene sheets were exfoliated from graphite oxide(GO) via thermal reduction (thermally reduced GO, RGO). Different dispersions of RGO sheets were prepared with and without ball mill mixing. It was found that the composites with highly dispersed RGO showed higher glass ...

Fracture mechanisms of epoxy-based ternary composites filled with rigid-soft particles
Epoxy composites filled with different amounts of aggregate-free silica nanoparticles and phase-separated submicron rubber particles were fabricated to study the synergistic effect of multi-phase particles
on mechanical properties of the composites. Compared with binary composites with single-phase particles, the ternary composites with both rigid and soft particles offer a good balance in stiffne...

A novel failure analysis of multi-walled carbon nanotubes in epoxy matrix
The failure analysis of reinforcing elements is of great significance to understand the structure-property relationship in polymer composites. Herein, we reported an improved methodology to ascertain and contrast the failure modes from one pair of homologous fracture surfaces of multi-walled carbon
nanotubes (MWCNTs)/epoxy samples at high-magnification using scanning electron microscopy....
