We extend the Clusters model to account for the presence of rigid inclusions and use it to analyze the experimental sintering kinetics of composites of 60SiO2 . 24B2O3 . 16Na2O glass particles and zirconia fibers. We followed the densification kinetics of such composites as a function of the particle size, volume fraction of fibers, fiber to pore size ratio, temperature, and time of thermal tre...

Man-made mineral fibers are produced using inorganic materials and are widely used as thermal and acoustic insulation. These basically include continuous fiberglass filaments, glass wool (fiberglass insulation), stone wool, slag wool and refractory ceramic fibers. Likewise, in the last two decades nanoscale fibers have also been developed, among these being carbon nanotubes with their high elec...

STATEMENT OF PROBLEM Despite the favorable properties of conventional PMMA used as a denture base material, its fracture resistance could be improved. PURPOSE This in vitro study was performed to determine whether the flexural strength of a commercially available, heat-polymerized acrylic denture base material could be improved through reinforcement with 3 types of fibers. MATERIAL AND METH...

Measurement of the wettability of a material is a predictive index of cytocompatibility. This study was designed to evaluate the effect of exposed E-glass fibers and bioactive glass (BAG) particles on the surface wettability behavior of composite implants. Two different groups were investigated: (a) fiber reinforced composites (FRCs) with different fiber orientations and (b) polymer composites ...

In this study, plasma polymerization technique was used to modify the surface of glass fiber under various plasma powers (30, 60 and 90 W) for exposure time of 15 min to improve the compatibility between glass fiber and epoxy matrix. γ -glycidoxypropyltrimethoxysilane (γ-GPS) monomer were used for surface coating of glass fiber. Interfacial properties of composites were investigated by short be...

Corrosion study of conventional reinforcement in concrete has been accorded wider importance the last few decades based on losses occurring monitoring structures. It is well known that presence chloride ions one most significant factors contributing to corrosion reinforcing steel. Practically, it observed marine environment, activating substances such as chlorides penetrate steel can counteract...

In this study, the effects of incorporating recycled photopolymer-plate residues from a packaging flexography process into polyester-glass fiber composites were examined. Ternary with an unsaturated polyester matrix elastomer particles evaluated using two types glass fibers: in forms fabric bidirectional fibers and blanket multidirectional fibers. The prepared by hand lay-up lamination differen...

In this study, six combinations of flax, hemp, and glass fiber were investigated for a hybrid reinforcement system in a polyurethane (PU) composite. The natural fibers were combined with glass fibers in a PU composite in order to achieve a better mechanical reinforcement in the composite material. The effect of fiber hybridization in PU composites was evaluated through physical and mechanical p...
