The development of bioactive glasses, which began with the Hench’s invention Bioglass®, has considerably advanced over past 20 years toward creation materials that not only chemically bond to living tissue, but also promote tissue regeneration. Some inorganic ions have effect stimulating cells and promoting biological functions, including bone formation. Glass-based a significant advantage in c...

The influence of the fiber used as reinforcement in resin matrix composite materials submitted to repeated low energy impacts is analyzed. The aramid, glass and carbon fiber composites were submitted to drop weight tests from 0.5m and from 1m. The number of impact events necessary to cause failure was recorded, and the fracture characteristics of each composite were analyzed by optical microsco...

Fracture surface characteristics of Te2As3Se5 (TAS) glass fibers aged in light and in dark have been investigated respectively for understanding physical aging effect on their fracture behavior. The properties including tensile strength ( ), surface flaw depth ( ), and mirror radii (rm) were measured by DY30 Adamel Lomarghy and SEM respectively. Shape factor extracted by fitting of vs confirms ...

In a previous study, we demonstrated that the length of glass fibers was a critical determinant of fiber potency in induction of tumor necrosis factor (TNF)-alpha and that activation of NF-kappaB was an important factor in this response. In the present study, we analyzed the role of mitogen-activated protein (MAP) kinases in the induction of TNF-alpha by glass fibers. Glass fibers induced phosp...

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...

Regardless of the excellent properties of glass ionomer cements, their poor mechanical properties limit their applications to non-load bearing areas. This study aimed to investigate the effect of incorporated short, chopped and randomly distributed flax fibers (0, 0.5, 1, 2.5, 5 and 25 wt%) on setting reaction kinetics, and mechanical and morphological properties of glass ionomer cements. Addit...

The objective was to investigate the mechanical properties, fluoride release and apatite formation of resin based dental composites on a containing Bioactive Glass (BG) with without silylating agent. A SiO2–P2O5–CaO–SrO–Na2O–CaF2 BG synthesized by melt quench route. This glass commercially available inert (IG) were incorporated into light cured BisGMA-TEGMA resin. composite resins then evaluate...
