Effects of amino-functionalized MWCNTs on ballistic impact performance of E-glass/epoxy composites using a spherical projectile

Mechanical and ballistic analysis of aramid/vinyl ester composites

“…For this reason, there is an increasing demand for the use of polymeric composites in defense applications like naval ships, warplanes, armored vehicles and re-entry vehicles. [1][2][3][4] Aramid, carbon, ultrahigh molecular weight polyethylene and glass fibers are the main reinforcements that have been widely used in high-performance composites. Among these materials, aramid-reinforced composites are known to have one of the best protection-to-weight ratios, high impact and compressive strength, and thus it is commonly applied in components subjected to impact loads, as well as in the lightweight armors production.…”

“…8 When the composite is subjected to high velocity impact, it hinders the projectile by absorbing kinetic energy following a variety of mechanisms such as cone formation, tensile failure of primary yarns, elastic deformation of secondary yarns, matrix cracking and delamination. 2 Furthermore, to avoid failures in the composite during a ballistic event, it is necessary that the high impact energy applied to it is absorbed within a short time frame. 10 For instance, some studies analyzed ballistic impact in thermoset polymer composites, 7,11-13 e.g.…”

Investigation of polycarbonate/acrylonitrile butadiene styrene/multiwall carbon nanotube nanocomposites under impact loading

“…Also, the energy absorption behavior at V 5 0 shows the same trend for different samples, in which the amount of the increase in the energy absorption of the control blend samples containing 1, 2, and 4 wt% are 44%, 121%, and 58%, respectively. As discussed by Rahman et al , one of the effective parameters that contribute to the high‐velocity impact properties of polymer composites is the capacity for easy stress transfer between various compositions of nanocomposite alloys, which strongly depends on improved dispersion. However, the good dispersion of nanotubes in polymer alloys improves interfacial properties by bridge formation between polymer components and MWCNT and finally enhances interfacial adhesion of PC and ABS .…”

Ballistic and impact protection finishes for textiles

“…According to the promising global market in Europe and worldwide for ballistic protective textiles, some research efforts have been already made to improve ballistic and other protective textiles in the area of new fi bre materials (i.e. SWCNTs (Ericson, 2004 ), MWCNTs (Rahman et al ., 2013 ) and nanofi bres (Thilagavathi et al ., 2008 )) and yarn/fabric structures and textile architecture (i.e. layer sequencing, incorporation of nonwovens, composite structures).…”
