VIRTUAL COMPOSITE - AN EFFECTIVE TOOL OF RESEARCH

摘要

The paper deals with analysis of the structure of textile composite. The quasi-periodic yarn shape, as basic structure unit, is modelled by the Fourier series that allows high flexibility, for example very effective approximation. Amplitudes and phase constants in Fourier series exhibit the distribution very similar to normal one. By the use of random number generators, virtual yarns can be generated and virtual composite realised from them. The structures are effectively visualised by a virtual reality system. The method of visualisation allows the immediately use of finite element method to predict the properties of virtual composite. Efficient model of virtual composite saves a lot of expensive experimental work.
