Automated geometric modelling of textile structures
An automated approach (TexGen) for modeling the geometry of textile structures is presented. This model provides a generic approach to the description of yarn geometry and yarn interlacement for all types of weaving. One feature of this model is that the shape and size of the cross sections may change locally; this is exploited in the functions for interference correction, which modify the textile according to geometric considerations to avoid penetration of yarns. Another feature of this model is that it acts as a pre-processor for finite element simulations by generating a mesh, definition of contact, materials orientation and boundary conditions, thus providing an automatic procedure. This paper describes the modeling techniques, algorithms and concepts implemented in TexGen and examines the functionality of their implementation for a range of two-dimensional/three-dimensional commercial fabrics. Comparisons between the images of real fabrics and modeled fabric structures confirm that the software is capable of modeling sophisticated fabric architectures, including twisted yarns with varied yarn cross sections. Accurate input measurements of fabric geometry are critical for successful results. The paper also discusses directions for further development of the approach to overcome current limitations.

Transmission of ultraviolet light through reinforcement fabrics and its effect on ultraviolet curing of composite laminates
The ultraviolet transmission of various reinforcement textiles was quantified experimentally for the case of incidence of light normal on the fabric plane, and correlated with the curing behavior of laminates incorporating these fabrics. For glass fiber fabrics wetted with polyester resin, light is transmitted through the voids between the fiber bundles and through the fiber bundles. Multiscale modeling of the fabric geometry allows the local transmission to be estimated and the average total transmission to be quantified. The results of curing experiments suggest that the degree of through‐cure achieved after a given cure time is correlated to the fabric transmission. Both are determined by the laminate thickness, the fabric architecture and the fiber volume fraction, i.e., the fiber packing density. While the transmission is reduced by the presence of the reinforcement fabrics, the total resin volume is reduced when compared with that of a resin only sample of the same thickness. A lower radiation dose is sufficient for curing, which partially compensates for the effect of reduced transmission. POLYM. COMPOS., 2008. © 2008 Society of Plastics Engineers

A Refusal and Traversal: Robert Cunninghame Graham's Engagement with Orientalism in Mogreb-el-Acksa
In his fin-de-siècle Morocco travelogue Mogreb-el-Acksa, Robert Cunninghame Graham refused and traversed Orientalist literary discourse. This essay explains how remarkable this refusal and traversal was, given Cunninghame Graham's print culture context and the pressures and pleasures of Orientalist discourse. Most important, the essay distinguishes Cunninghame Graham from his literary peers, especially his friend Joseph Conrad.
