Abstract:
The production technology of reinforcement filler for new multifunctional polymer based composites with weft-knitted structure had been proposed. In such reinforcement filler high-strength carbon fibers (CFs) from PAN precursors (wefts) were laid in a knitted fabric as straight continuous yarns, so in such case these CFs were not twisted by knitting machine to form the loops. Various kinds of chemical and inorganic fibers can be used as base yarn in this case, in particular glass, aramid, carbon fibers from hydrate cellulose and etc. Properties of multifunctional polymer-based composite materi

The surface characteristics of a solospun roller are important to the properties of solo-sirofil yarns. In this research, a three-level, three-factor, orthogonal experimental design (33) was used to investigate the effect of a solospun roller diameter, groove width and groove depth on the hairiness of cotton/polyester composite yarn. Solo-sirofil yarns with different solospun rollers were produced, and the hairiness was tested. It was shown that the hairiness of the solo-sirofil composite yarn was reduced by 44% compared to that of the sirofil. The structure of the solo-sirofil was improved wh

The textile reinforcements used for composites are multiscale materials. A fabric is made of woven yarns themselves composed of thousand of juxtaposed fibres. For the simulation of the draping of these textile reinforcements several families of approaches can be distinguished in function of the level of the modelling. The continuous approaches consider the fabric as a continuum with a specific behaviour. The discrete approaches use models of some components such as the yarns and sometimes the fibres.
