Reactive material linear shaped charges
WebFeatured Application: This work provides a new type of linear shaped charge, and it is meaningful for the structural design of the novel linear shaped charge. Abstract: In this paper, a... WebCompared with the conventional copper liner, the reactive material liner can shape jet in a shorter time, but the jet break easily and lose stability due to its poor ductility. Although the penetration depth is sacrificed slightly when penetrating steel target, the reactive material liner produce a significantly enlarged hole-diameter.

WebShaped Charge Shaped charges are devices in which an explosive load is used to collapse a (usually metal) liner, thereby creating a high velocity jet that is capable of penetrating deep into metal, concrete or other target materials (Walters & Zukas, 1989). From: Advances in Applied Mechanics, 2024 View all Topics Add to Mendeley About this page WebTo study the penetration and cratering effect of reactive material composite jets, a series of experiments are carried out for the shaped charge (SC) with different composite liners damaging steel targets. The inner layer of composite liners is metal and the outer one is a polytetrafluoroethylene/aluminum (PTFE/Al) reactive material. Copper (Cu), titanium (Ti) …
