Interlacing is commonly used in textile industries to produce cohesion points (knots) in a multi-filament yarn. The knots distance needs to be controlled on-line since its regularity guarantees a homogeneous appearance of the final fabric. Here, we investigated two techniques for the on-line monitoring of the multi-filament yarn interlacing. The high speed imaging of the yarn motion in an interlacer...
A DGEBA-based epoxy matrix was loaded with 10, 20 and 30phr of fumed silica particles. Single edge notched bend (SENB) specimens were prepared and deformed to failure in three-point bending configuration. Their fracture surfaces were examined by atomic force acoustic microscopy (AFaM) in order to obtain information about the local elastic modulus of the surface at high spatial resolution. The collected...
DGEBA-based epoxy nanocomposites filled with various amounts of fumed silica nanopowders (10, 20 and 30phr corresponding to 3.3, 6.4 and 9.2% by volume) were prepared by a solvent assisted dispersion procedure. The obtained nanocomposites were analyzed by means of differential scanning calorimetry, dynamic-mechanical thermal analysis, uniaxial tensile tests on un-notched samples and three-point bending...
