This review summarizes the current state of polymer composites used as dielectric materials for energy storage. The particular focus is on materials: polymers serving as the matrix, inorganic fillers used to increase the effective dielectric constant, and various recent investigations of functionalization of metal oxide fillers to improve compatibility with polymers. We review the recent litera...

Flowable composite resins are widely used in clinical practice. Bulk Fill flowable resins with improved mechanical and chemical characteristics have recently been introduced. These composites are low-viscosity materials with the reduced percentage of inorganic filler particles and higher amount of resinous components. Consequently, the polymerization process leads to volumetric contraction, but...

CuO and V₂O₅ graphene quantum tunneling composites (GQTC) presented in this article were produced and their sensory properties were analyzed. The composites were synthesised using two stage high-power milling process, which resulted in materials that have good temeprature and pressure sensory properties. Described production process defines internal structure of materials such that when used as...

Polymer composites are among the most rapidly growing research fields in material science. Polymer composites are adding a great deal of material that is more durable and useful as compared to the conventional material. Properties of composite materials greatly depend on the nature, proportion and compatibility of the components of the composite materials. In this paper we have conducted an ana...

Computational and analytical studies of degradation of wind turbine blade materials at the macro-, micro-, and nanoscale carried out by the modelling team of the Section Composites and Materials Mechanics, Department of Wind Energy, DTU, are reviewed. Examples of the analysis of the microstructural effects on the strength and fatigue life of composites are shown. Computational studies of degrad...

The authors have analyzed the isotropic thermal/electrical conductivities of two types of specially structured composite materials. Closed-form results have been obtained for predicting the conductivities of the composites, and the accuracy has been verified by FE simulations. The obtained results in this paper are compared to the relevant theoretical predictions and experimental measurements. ...

The marginal fracture toughness of several types of composite resins was determined by means of the rattler test. Microparticle-filled resins showed significantly higher marginal fracture toughness than conventional composites. Posterior restorative composites were intermediate between MFRs and conventional composites. Amalgams were inferior to restorative resins. These data correspond with the...

Hydrogels, electrospun fiber mats (EFMs), and their composites have been extensively studied for tissue engineering because of their physical and chemical similarity to native biological systems. However, while chemically similar, hydrogels and electrospun fiber mats display very different topographical features. Here, we examine the influence of surface topography and composition of hydrogels,...

INTRODUCTION Composites have become an important group of engineering materials, as they offer better physical and mechanical properties in comparison to unreinforced materials. Different types of materials can be used as the matrix of composites, including metals, polymers and ceramics. An important aspect of researches on composites has been the investigation of their mechanical properties [1...

The efficacy of composite materials for bone tissue engineering is dependent on the materials' ability to support bone regeneration whilst inducing a minimal inflammatory response. In this study we examined the in vitro osteogenic and inflammatory properties of poly(3-hydroxybutyrate-co-3-valerate) (PHBV) with various calcium phosphate-reinforcing phases: nano-sized hydroxyapatite (HA); submicr...
