This paper collects very important mechanical properties of laminate composites for industry of laminate structures. We found very important results for various stacking sequences of glass/epoxy laminate composites. On the other hand, we determined the properties of the materials during manufacturing process in the company, which produced mechanical parts in railway industry. Our results can he...

Abstract This research aims to discuss and determine acoustic performance values for impact noise insulation (L’nT,w) 39 floor system compositions that have different resilient materials wooden laminate finishing. The methodology is organized according ISO 16283-2, 717-2 NBR 15575-3 classification. results obtained demonstrate the prefabricated ribbed slab with prestressed joists ceramic slabs,...

Piezoelectric materials can be used as actuators for the active vibration control of smart structural systems. In this work, piezoelectric patches are surface bonded to a composite laminate plate and used as vibration actuators. A static analysis based on the piezoelectricity and elasticity is conducted to evaluate the loads induced by the piezoelectric actuators to the host structure. The load...

This paper presents buckling studies made on skew plates using finite element. The effects of the skew angle, aspect ratio, length-to-thickness-ratio, fibre orientation angle, and numbers of layers in the laminate and laminate sequence on the critical buckling load factor (Kcr) of antisymmetric composite laminates have also been presented. The critical buckling load factor (Kcr) is found to inc...

The stability and low melting point make ionic liquids favorable electrolytes to be used in a wide range of electrochemical systems. The application field includes lithium ion batteries, electric doublelayer capacitors (EDLCs), and ionic electromechanically active polymer (iEAP) actuators. The iEAP is a laminate structure that consists of electronically conductive high surface area electrodes b...

A hybrid composite architecture of carbon nanotubes (CNTs), advanced fibers and a matrix is described, from CNT synthesis and characterization through to standard mechanical and electrical laminate tests. Direct growth of aligned CNTs on the surface of advanced fibers in a woven fabric enables enhancement in multifunctional laminate performance, as demonstrated by a 69% increase in interlaminar...

introduction: the purpose of the presented study was to evaluate the effect of zirconia thickness on the tensile stress of zirconia based all-ceramic restorations. methods: twenty zirconia disks with 10mm diameter were prepared in two groups using cad/cam system. the thickness of zirconia was 0.5mm in first group and 0.3mm in second group. after sintering, 0.4mm glass ceramic porcelain was appl...
