Ultrasound and Textile Technology – Cellular Automata Simulation and Experiments
نویسندگان
چکیده
A summary of usage of ultrasound in traditional textile technologies and a present literature review about new possibilities of usage of ultrasound in textile branch are the first part of this contribution. Second part is focused on a possibility of computer simulation of high frequency wave propagation by means of cellular automata method. An own program for longitudinal harmonic wave simulation is designed. Results of computer simulations of wave motion through different porous structures are presented. Wave attenuation in respect of frequency and then different porous structures is studied. The last part of this contribution – an experimental part – is attended to production of composite materials reinforced by electrospun nanofibers, where the impregnation of nanofiber layers by liquid matrix proceeded by means of ultrasound. The usage of ultrasound improved the impregnation process (mainly for high viscous liquid matrixes) and thus a content of fibers in a complete composite material reinforced by polyvinyl alcohol electrospun nanofiber layers.
