The synergistic effects of reactive polyol diluent and amino-functionalized multi-walled carbon nano-tubes on fracture of two-and three-phase (hybrid) epoxy nanocomposites are investigated under quasi-static and dynamic loading conditions. Digital image correlation method with a drop-tower and high-speed camera are used for dynamic tests. The crack-tip deformation histories and fracture paramet...

The mechanical properties of different polymer matrix composites are discussed in this research study. These multiphase materials which reinforcing elements and a suitably combined. 18 PMCs, including nylon 66 reinforced with 5, 15, 25% wt% silicon carbide (SiC) boron (B4C), were evaluated using an injection moulding technique at three pressures optimization process parameters like reinforcemen...

An actively cooled vascular polymer matrix composite containing 3.0% channel volume fraction retains greater than 90% flexural stiffness when exposed continuously to 325 °C environmental temperature. Non-cooled controls suffered complete structural failure through thermal degradation under the same conditions. Glass–epoxy composites (T g = 152 °C) manufactured by vacuum assisted resin transfer ...

A three-dimensional micromechanics-based analytical model is developed to study thermo-mechanical properties of polymer composites reinforced with randomly distributed silica nanoparticles. Two important factors in nanocomposites modeling using micromechanical models are nanoparticle arrangement in matrix and interphase effects. In order to study these cases, representative volume element (RVE)...

Polymer matrix composites (PMCs) may be found in nearly every facet of modern society, from electronic components to a broad range accessories. contain materials that include polymer. It is also made up multiple continuous and short fibres are held together the organic polymer matrix. In this article, development, properties, production along with electronics applications were discussed. The ma...

This investigation was focused on evaluating the utilization of Leather-waste, i.e., “Leather Shavings”, to develop “Poly(ethylene-vinyl-acetate)” (EVA) based “polymer matrix composites”. Composites with highest ratio 1:1 were developed using a rolling-mill, which then subjected hot-press molding for value-added applications, notably in “floor-covering”, “structural”, “footwear”, and “transport...

Femtosecond transient absorption measurements on single wall carbon nanotube/poly(3-hexylthiophene) composites are used to investigate the relaxation dynamics of this blended material. The influence of the addition of nanotubes in polymer matrix on the ultrashort relaxation dynamics is examined in detail. The introduction of nanotube/polymer heterojunctions enhances the exciton dissociation and...

Glass fiber reinforced polymer composites are one of the most widely used composite materials. The addition of Coal ash to polymer matrix dramatically increases the overall mechanical strength of the composite material as compared to the polymer composite. In view of this, a method is proposed for mixing coal ash powder (size 52-75 μm) into resin and Ash reinforced polymer composites are fabric...

This review provides a comparison of submicron-diameter carbon filaments and conventional carbon fibers as fillers in composite materials. Carbon filaments (0.1 mm diameter, catalytically grown) are superior to conventional carbon fibers (discontinuous) as a filler in providing polymer–matrix and cement–matrix composites for electromagnetic performance, but are inferior to the fibers as a fille...

The special topic ‘‘Metaland Polymer-Matrix Composites’’ is intended to capture the state of the art in the research and practice of functional composites. The current set of articles related to metal-matrix composites includes reviews on functionalities such as self-healing, self-lubricating, and selfcleaning capabilities; research results on a variety of aluminum-matrix composites; and invest...
