Qualification and Quantification af Firearm Damages of High-Performance Materials

Today, textile fibres and materials are besides producing garments, also used for a wide range of other products such as: different types of transport vehicles, sportswear, protective equipment, etc. Textile fibres are also increasingly used as structural materials, in so-called fibres reinforced composites. Such variety of textile usage cause their frequent occurrence as material traces in criminal act or accidental situations. The qualification and quantification of high- performance materials damages are extremely difficult especially when it comes to damages caused by firearms. In this work, through systematic approach and the application of standardized destructive and/or new, non- destructive textiles testing methods, the possibilities of objective evaluation of high-performance composite materials damages caused by firearms have been explored. Special attention was put on the impact of firearm types (different calibre) and firing distance on the resulting damages of modern composite materials. Acquired findings enable the exact characterization of created damage as well as the type of weapons that committed the criminal offense, which is one of the basic prerequisites in dealing with crimes.
