The bias-extension test is one of the methods to characterise intra-ply shear behaviour continuous fibre reinforced composites including fabrics and unidirectional (UD) materials. For determination major mechanical properties metals, often a uniaxial tensile used. Combination these two for deformation hybrid metal-composite laminates proposed comparing method cross-plied prepregs woven fabric p...

This paper focuses on parametric model order reduction (PMOR) of guided ultrasonic wave propagation and its interaction with damage in a fiber metal laminate (FML). Structural health monitoring FML seeks to detect, localize characterize the high accuracy minimal use sensors. can be achieved by inverse problem analysis approach, which employs signal measurement data recorded embedded sensors str...

re-establishing a patient’s lost dental esthetic appearance is one of the most important topics for contemporary dentistry. new treatment materials and methods have been coming on the scene, day by day, in order to achieve such an aim. most dentists prefer more conservative and aesthetic approaches, such as direct and indirect laminate veneer restorations, instead of full-ceramic crowns for ant...

AIM The aim of this report is to present five-year follow-ups of two different applications for the use of direct laminate resin-based composite veneers to improve esthetics. BACKGROUND Defects in the maxillary anterior teeth, such as enamel hypoplasia and peg lateral, can present esthetic challenges. Furthermore, a treatment plan that can be completed in a single appointment is highly desira...

Adhesively bonded repair patches are an excellent approach for repairing locally damaged composite components. If correctly applied, fiber-reinforced may restore/increment the mechanical response of laminates without significantly increasing structure’s mass or altering its geometry. However, in order to take full advantage this technique, one must employ with a minimal surface area and maximum...

The fracture toughness of a polymer-metal laminate composite is obtained by mechanical testing of a specimen containing a pre-crack. The laminate is a material used for packaging. It consists of a thin aluminium foil and a polymer coating. A centre cracked panel test geometry is used. Each of the layers forming the laminate is also tested separately. The result is compared with the measured fra...

OBJECTIVES The aim of this study was to evaluate the clinical performance of posterior, metal-free polymer crowns with and without a glass-fiber framework, in comparison to metal-ceramic crowns. METHODS After randomisation, 80 single crowns, manufactured from a newly designed polymer composite, were set in posterior teeth. Half of these received a glass-fiber framework, while half were prepar...

This research paper compares the thermal conductivity and thermal expansion coefficients of glass fiber reinforced epoxy composite laminates (GFRP laminates) made using the Hand layup technique. The composite laminates were fabricated by filling with varying concentrations of fly ash, stone powder, aluminium oxide (Al2O3), magnesium hydroxide (Mg (OH)2), Silicon carbide particles(SiC) and hemat...

fiber/ metal laminates (fmls) are hybrid composites consisting of alternating thin layers of metal sheets and fiber reinforced epoxy laminates. in this study, the effect of fiber orientation on impact properties of fml plates is investigated both analytically and experimentally. two groups of specimens were prepared and tested in two different levels of impactor energy. the indentation depth an...

A glass fiber reinforced plastic laminate, which consists of half-overlapped wrapped Kapton/R-glass-fiber reinforcing tapes vacuum-pressure impregnated in a cyanate ester/ epoxy blend, is proposed as the insulation system for the ITER Toroidal Field coils. In order to assess its mechanical performance under the actual operating conditions, cryogenic (77 K) tensile and interlaminar shear tests w...
