This paper investigates the effect of transverse impact loading on in-plane shear behaviour two laminate configurations. The extensive experimental studies consider a pure carbon (type 1) and novel X-shaped carbon/glass 2). results establish that all three graduated energy levels (5J, 7.5J 10J) induce through-thickness matrix cracking, fibre breakage delamination in type 1 laminate. However, us...

A comparison between the vibration of fiber-metal laminate (FML) and composite cylindrical shells has been studied in this manuscript. Love’s first approximation shell theory has been applied to obtain Strain-displacement relations. In addition, beam modal function model has been used to analyze the cylindrical shell with different boundary conditions. In this manuscript, the frequencies of FML...

The design of thin-walled cylinders in axial compression is limited by sensitivity to geometric imperfections. This paper focuses on reducing this imperfection from a perspective. By using variable-angle composites, the load paths are tailored reduce effective area over which imperfections can initiate buckling. Continuous Tow Shearing (CTS) one such manufacturing technique. It does not cause d...

Abstract GLARE laminates are multi-layered metal-composite materials created from bonding sheets of metallic alloys with carbon or glass fibre layers. The application hybrid-conventional machining processes such as ultrasonic-assisted drilling (UAD) is becoming great interest to the aerospace industry due its capability in reducing cutting forces and tool wear which directly responsible for dri...

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...

Fiber-metal laminates (FMLs) such as Kevlar reinforced aluminum laminate (ARALL), 18 Carbon reinforced aluminum laminate (CARALL), and Glass reinforced aluminum laminate 19 (GLARE) offer great potential for weight reduction applications in automobile and aerospace 20 construction. In order to investigate the feasibility for utilizing such materials in the form of 21 laminates, sheet hydro-bulgi...

This work aims to improve the flexural behaviour of unidirectional fibre-reinforced laminates by means coupling an optimization procedure for quasi-isotropic configurations with design space opened dispersed-ply orientations. The approach consists finding suitable alternatives traditional (with fibre orientations limited 0°, ±45∘, and 90°), while maintaining their stiffness characteristics. str...
