Unlike hang gliders, their close relations, paragliders have no rigid framework; the parachute canopy acts as a wing and is constructed of fabric cells with openings at the front that allow them to be inflated by movement through the air the "ram-air" effect.
Much effort has been done to engineer artificial fabric cell-laden scaffolds which are widely used for a great diversity of linear tissue constructs.
The approach was incrementally employed whereby the model predicts the composite fabric unit cell effective modulus, processing-induced strains and stresses (thermal expansion and chemical shrinkage) during cure.
Highly structured and hierarchal textiles may be modelled at three scales, ranging from micro modelling of individual fibres within a yarn via meso-scale modelling of a fabric unit cell through to macro-scale modelling of a whole product.
Applied exclusively on particle-type composites, this paper demonstrates that they can model woven laminated composites with very valuable issues as they are able to capture with high spatial resolution the details of the stress and strain fields in the fabric periodic cell.
"Regenerative medicine," as some call it, would depend not on scalpels and poisons but on the same agents the body itself uses to repair its own fabric -- cells and chemical signals.
The good news is that recent advances in plastics and nanotechnology are speeding up the development of cheap, flexible cells that can be sprayed on walls or even printed on paper and fabrics.A solar cell is made of semiconductive film sandwiched between two electrodes.
Furthermore, the study permits a reliable prediction of mechanical behavior of woven fabric composites unit cells in which the weave patterns are the variables.
This study addresses the optimization of the elastic properties within woven fabric composite unit cells with multiple designs based on periodic boundary conditions and evolutionary algorithms.
The system, devised by Sheffield university and the London College of Fashion, follows similar 'smart' applications at Bolton University, which generate electricity through minute solar and movement cells in fabric.
