Intra-radicular loss of tooth structure in endodontically treated teeth poses a challenge. Available methods for treatment are cast post-core, intra-radicular resin reinforcement using composite resin followed by placement of prefabricated metal/fibre post (glass or carbon).This study is an attempt to investigate the validity of treatment of such teeth using above methods and evaluate which pos...

The effect of matrix and fibre cracks on the static strength stiffness uni-directional plies cross-ply laminates under tensile loads was examined with goal understanding main damage mechanisms. size emanating from cracked fibres determined found to be in excellent agreement test results. This used predict failure shown good results for six different materials. approach extended fatigue loading ...

The advent of novel robot-assisted composite manufacturing techniques has enabled steering fibre paths in the plane lamina, leading to emergence so-called variable angle tow (VAT) laminates. These laminates, with spatially varying orientations, provide designer ability tailor point-wise stiffness properties VAT composites substantially more efficient structural performance over conventional str...

The use of recycled and renewable components in structural applications supports the development sustainable lightweight structures. Disposed bottle caps can be used to generate eco-friendly honeycomb cores, especially when combined with other components. A natural fibre-based laminate represents an alternative synthetic fibres, matrices, metals skins for sandwich panels. This study evaluates f...

Porcelain laminate veneers are used routinely in cosmetic dentistry. The public usually refers to this mode of treatment simply as “veneers.” Their popularity has increased because of television makeover programs, commercials, and magazine advertisements. Porcelain laminate veneers have so increased in their attractiveness that the general public is demanding this type of instant makeover. Furt...

The adhesion strength of a Cu/Cr/polyimide (PI) flexible copper clad laminate (FCCL), which was manufactured by the roll-to-roll process, was evaluated according to the thickness of the Cr seed layer using the 90 peel test. The changes in the morphology, chemical bonding and adhesion properties were characterized by scanning electron microscopy, atomic force microscopy and X-ray photoelectron s...

AIM To evaluate the effect of quartz-fibre posts on the depth of polymerization of a dual-cure resin cement using Raman spectroscopy and to determine the physical properties of the polymerized cement using a dynamic mechanical analyzer (DMA). METHODOLOGY Twenty-five fibre and 25 CrNi posts were used to evaluate depth of polymerization. Posts were cemented with dual-cure resin into root canals...
