Characterization of debris cloud distribution and damage caused by hypervelocity impacts on vapor grown carbon nanofiber reinforced laminate shielding Conference Paper uri icon

abstract

  • The debris cloud formation associated with small particle hypervelocity impacts (HVIs) to laminated composite shields was conducted using a micro twostage light gas gun. Woven fabric E-glass/vinyl ester (VE) composites and Eglass/ VE/vapor grown carbon nanofiber (VGCNF) hybrid composites were subjected to small particle impacts with impact velocities in the range of 3.4km/s to 4.7km/s. A pristine 6061 aluminum plate was employed as the back wall on which the debris cloud impacted with a standoff distance of 19.1mm. This back wall was then visually inspected as well as viewed using SEM. The impacts produced slightly different types of damage to the composite shielding, and the damage to the back wall was consistent with that associated with laminated shield impacts.
