摘要: Abstract This paper reports a study of the laser transmission welding polymeric joints composed by two ABS (acrylonitrile/butadiene/styrene) sheets, one transparent (natural ABS) and other absorbent (filled different percentages carbon nanotubes (CNTs)). The objective this work is to analyze effect process parameters CNTs concentrations on weld formation mechanical resistance joints. Thermal optical characterizations natural doped sheets are studied. Microscopic characterization top cross sections joining were carried out corresponding widths integrity. optimal welded was checked shear tests. capability investigated as function filler concentration. results concerning material integrity suggest high sensitivity with concentration specific changes in incident intensity. can be related properties polymer.
