Abstract Graphene is extensively used as a functional material due to its superb heat transfer and electrical conductivity properties. In this paper, sample graphene oxide /glass fiber/epoxy resin composites were prepared by ultrasonic decentralization. The stress distribution of the graphene-doped fiber-reinforced matrix simulated mathematical modelling. reliability numerical model illustrated...

Epoxy nanocomposites of different content of carbon nanofibers upto 1 wt% have been fabricated under room temperature and refrigerated curing conditions. The composites were studied in terms of mechanical and electrical properties. Flexural modulus and hardness were found to increase significantly in refrigerated samples due to prevention of aggregates of nanofibers during cure condition. Incre...

58 INTERNATIONAL DENTISTRY SA VOL. 8, NO. 4 Introduction The clinical success of fiber post-retained restorations depends on the establishment of a reliable bond at the root-post-core interfaces. In spite of the improvements in dental material technology, post to composite adhesion is still considered relatively low. Advances in silane coupling agents enhance bond strength by promoting adhesion...

The curing kinetics and viscosity of an epoxy resin system, SI-ZG-5A, have been characterized for application in the vacuum assisted resin transfer molding (VARTM) process. Impregnation of a typical carbon fiber perform provided the test bed for the characterization. Process simulations were carried out using the process model, COMPRO [8], to examine heat transfer and curing kinetics for a full...

The objective of this study is to develop a multiscale modeling approach to predict the influence of molecular structure and microstructure on the bulk-level properties of a graphite/epoxy plain-woven fabric composite in which the resin-rich regions are reinforced with carbon nanotubes. The modeling approach incorporates molecular modeling and micromechanics techniques. A parametric study shows...

The interfacial designing of carbon fiber (CF)/epoxy composites, as a well-accepted method used to obtain high-performance has gained extensive attention. However, an improvement in adhesion is usually accompanied by simultaneous decrease toughness, which become obstacle the performance enhancement CF/epoxy composites. Herein, nanosized UiO-66-NH2 was proposed yield on CF surface through situ g...
