During the past 15 years NASA has taken the lead role in exploiting the benefits of textile reinforced composite materials for application to aircraft structures. The NASA Advanced Composites Technology (ACT) program was started in 1989 to develop composite primary structures for commercial transport airplanes with costs that are competitive with metal structures. As part of this program, sever...

This thesis examines the capability of current techniques in fiber classification such as UV-visible microspectrophotometry (MSP) (for dye in situ and/or extracted) to discriminate between fibers from sources known to be different. When these methods fail to adequately distinguish the fibers, novel alternative techniques, such as pulsed pumped laser-induced fluorescence spectroscopy (LIF) and l...

Devices for the measurement of airborne fiber concentration currently existing on the market show significant disadvantages. Due to e.g. multi-step measurement principles or bulky design, existing devices are not capable to be used for specific applications. Knowledge of airborne fiber concentration is essential to determine operation conditions and air quality in e.g. textile mills, museums or...

There is a growing interest in fibers supporting optoelectrical properties for textile and wearable display applications. Solution-processed electroluminescent (EL) material systems can be continuously deposited onto fiber or yarn substrates in a roll-to-roll process, making it easy to scale manufacturing. It is important to have precise control over layer deposition to achieve uniform and reli...

Fibers comprise probably the most common form of trace evidence in forensic science today. They occur in perhaps one-quarter of all cases that involve trace evidence and a large majority of crime laboratories routinely characterize textile fibers. Although a great deal of research has been done on how to best characterize and compare fibers, relatively little time has been spent on determining ...

Shielding of instruments and humans from electromagnetic interference (EMI) has become increasingly important during the last decades due to more machines devices radiating waves. While several applications can use rigid shields, flexibility is enabled by developing bendable, drapable, ideally even stretchable EMI shielding. Textile fabrics have these properties, combined with potentially good ...

one of the main issues of nanotechnology is producing materials with new properties. nanotechnology, as a powerful tool, has the ability to create evolution in the agricultural system and food–medicinal industries across the world. producing a high-performance material from reclaimed cellulose material will increase motivation to recycle these materials at all phases of paper production and rem...
