In the last 30 years since their introduction into aerospace applications, composites have become increasingly used, making up as much as 50% of modern aircraft by weight. Considering this fact, it is surprising that most aircraft today are only scratching the surface of the true potential of composite technology with traditional uniaxial fibers. With the introduction of Automated Fiber Placeme...

Increasing evidence shows that complex diseases are caused by both common and rare variants. Recently, several statistical methods for detecting associations of rare variants have been developed, including the test for testing the effect of an optimally weighted combination of variants (TOW) developed by our group in 2012. These methodologies consider phenotype measurement at only one time poin...

BACKGROUND Return to work is an important outcome following traumatic work-related hand injuries. It is unclear how psychosocial factors affect the time to return to work following traumatic work-related hand injury. AIMS To investigate the relationships between hand injury severity, self-perceived health, demographics and time off work (TOW) following traumatic work-related hand injuries and...

The fundamental frictional behaviour of carbon fibre tows relevant to composite fabric forming is explored. Tow-on-tool and tow-on-tow contact are considered. For tow-on-tool contact, an experiment is devised to simultaneously observe the true filament contact length and measure the friction force over a range of normal loads. Filament contact length is not constant, as would be given from an i...

The aim of this study is to see what the influence of tow-bars is in rear-end collisions, hereby looking at the crash pulse. The database from the Swedish insurance company Folksam and some full-scale tests performed by Autoliv [I, 241 give an indication that the tow-bar increases the injury risk. The increased average acceleration correlates to the increased injury risk. First of all a literat...

A helical tow model of on-line curing of thermoset composites in winding is developed and solved numerically. Actual shape of tow in winding process is considered, and consequently, the modeling of the on-line curing process is more realistic. A numerical grid generation method is developed for the complicated geometry. Transformations of three-dimensional energy equation and its boundary condi...
