Models for Textile Composites Forming

INTRODUCTION Drape of dry fabrics or prepregs was recognised as an important feature in composites forming operations from the start. In the 1950s the first mathematical models were developed based on purely kinematic arguments. The assumption of zero fibre strains and trellis deformations led to the socalled fishnet approach. Typically, these methods require certain arbitrary constraints to re...

Multi-pass Gaussian Contact-hardening Soft Shadows

Real-time soft shadows have seen numerous improvements over the years. Post-process blurring of shadow edges are commonly used to hide aliasing artifacts, but in some cases, such as ours, it is used to mimic physical processes. Instead of generating penumbra regions uniformly, we scale key algorithmic components in screen space to allow the penumbra region to grow in accordance with occluder/re...

Contact Hardening Soft Shadows using Erosion

In this paper, we present an image based method for computing contact hardening soft shadows by utilizing an erosion operator. Our method is based on shadow mapping and operates in screen space. By using object silhouettes in hard shadows, we estimate the penumbra size and scale an erosion operator to generate the penumbra areas. Furthermore, we present two solutions to generate the shadow fact...

Complex Stamp Forming of Advanced Thermoplastic Composites

The inherent advantages of thermoplastics over the traditional thermoset composite systems are well recognized in the aeronautics community. The main advantages are the much faster processing and the higher toughness. The current advanced thermoplastic material systems provide excellent mechanical performance but their main disadvantage is the difficult processing. Ideally, future aircraft subc...

Stochastic simulation of woven composites forming

A stochastic forming simulation procedure is developed and implemented to investigate the effect of geometric variability in pre-impregnated woven textiles on manufacturing. Image analysis is used to characterise variability in tow directions and unit cell size in a pre-impregnated carbon/epoxy satin weave textile. It is found that variab ility in tow orientations is significant, whereas variab...
