Nanoscale thermal properties of carbon nanotubes/epoxy composites by atomistic simulations

نویسندگان

چکیده

Abstract Carbon nanotubes/epoxy composites are increasingly employed in several industrial fields, because of the enhanced material properties provided by nanofillers. In particular, thermal conductivity these nanocomposites is determined heat transfer mechanisms occurring over multiple scales, thus causing a complex relation between effective response and microscopic characteristics material. Here, epoxy reinforced carbon nanotubes investigated using atomistic simulations. For better understanding how arises from composite at nanoscale, its constituents studied separately according to different geometrical, physical chemical characteristics. The resin alone first molecular dynamics; then, Kapitza resistance nanotube–nanotube nanotube–epoxy interfaces as well. finally computed observed behavior interpreted on basis nanofillers, matrix alone. Results – verified against medium theory predictions show that, for considered configurations, nanocomposite increases with nanotube length volume fraction, curing degree system temperature. perspective, presented approach could be investigate other constitutive materials or nanocomposites.

Thermal Properties of Hybrid Carbon Nanotube/Carbon Fiber Polymer Composites

Carbon fiber reinforced polymer (CFRP) composites possess many advantages for aircraft structures over conventional aluminum alloys: light weight, higher strengthand stiffness-to-weight ratio, and low life-cycle maintenance costs. However, the relatively low thermal and electrical conductivities of CFRP composites are deficient in providing structural safety under certain operational conditions...

Methodology for Estimation of Nanoscale Hardness via Atomistic Simulations

Statistical mechanics has provided powerful techniques to measure mechanical properties of materials at the nanoscale and paved the way for bottom-up computational materials design. The introduction of such techniques in civil engineering applications, namely construction and geotechnical materials, remains limited to the elastic and fracture properties. This paper presents an atomistic approac...

Atomistic simulations on multilayer graphene reinforced epoxy composites

We use molecular dynamics simulations to characterize multilayer graphene reinforced epoxy composites. We focus on two configurations, one where the graphene layers are parallel to polymer/graphene interface and a perpendicular case, and characterize the in situ curing process of the resin and the thermo-mechanical response of the composites. The yield stress of the composites under uniaxial lo...
