By increasing the molecular weight of P3HT block from 7150 to 21,000 g/mol in a similar growth condition, the laminating numbers changed to 3 and 10 in toluene and xylene, respectively.
Use of the NDT impact-echo method presented in this paper may be effective in evaluating CFRP laminate bond condition on RC bridge structural members.
Laboratory tests of the impact-echo machine with associated signal analysis show a correlation between signal frequency and CFRP-laminate bond condition.
The following points can be concluded from the tests presented in this paper: 1. Use of the NDT impact-echo method presented in this paper may be effective in evaluating CFRP laminate bond condition on RC bridge structural members.
One sheet of NiO YSZ support (~300 μm), YSZ electrolyte layer (20 30 μm), and porous YSZ layer (~70 μm) were stacked together under a vacuum condition and laminated at 20 MPa for 10 min using a thermal isostatic press (30T Shanxi, China) to form a NiO YSZ supported tri-layer structure.
READ laminating directions thoroughly.
Finally, using either third order polynomial or trigonometric functions in thickness of the laminate, boundary conditions at the top and bottom of the laminate are used to reduce the number of unknown functions, which is only two.
Finally, based on these discussions, we present simple damage identifications with the embedded chirped FBG for the holed CFRP laminates under completely unloaded conditions.
A new micro-mechanical model is developed to predict the behavior of unidirectional polymer matrix composite laminates under impact loading conditions and implemented in the non-linear finite element software LS-DYNA.
Here, a model is presented to calculate the evolution of stress and deformation in single-curvature cold-bent laminated glass when, in particular, the glass plies are first cold-bent and, in this condition, are successively laminated in autoclave.
