Investigation into the Ballistic Properties of Three-Dimensional Braided Fabrics
MetadataShow full item record
High performance fabrics are an integral part of modern soft ballistic body armor. Currently, the most common practice has been to use woven fabrics in these applications. This work is intended as an early study exploring the feasibility of replacing these conventional fabrics with three-dimensional (3D) rotary braided fabric. Low velocity tests were conducted on plain woven and 3D braided fabrics to quantify out of plane deformation properties of the different fabric structures. A tensile tester was used to determine the force-displacement properties of one sample of each different fabric type. The single layer and four layer 3D braided fabrics were found to have similar specific energy absorption capabilities to the woven fabric. The two layer 3D braided fabric was found to have over 300% of the specific energy absorption of other fabric types, indicating that this class of fabrics may be made to have desirable qualities for soft body armor. Possible explanations for this occurrence include successive failure of the fabric structure layers and inconsistencies in fabric production, however, more experimentation is necessary to arrive at a satisfactory explanation for this phenomenon.
