US12319033 - Composite structure

There is provided a composite structure, comprising a protective structure comprising a plurality of ballistic layers arranged as a stack; and an ancillary structure adjacent to the protective structure adapted to at least partly absorb a force acting on the protective structure. The ancillary structure comprises at least one first layer comprising an aerogel arranged to at least partly absorb a force acting on the protective structure. A part of each ballistic layer is moveable relative to at least one adjacent ballistic layer and wherein a part of each ballistic layer is connected to at least one adjacent ballistic layer so as to restrict relative movement of a part of each of the adjacent ballistic layers.

The patent describes a composite structure for ballistic protection, featuring a stack of ballistic layers and an adjacent ancillary structure designed to absorb forces impacting the protective layers. This innovative design allows for selective movement between parts of the ballistic layers, enhancing the overall effectiveness of the protective system.

Claim 1

A composite structure, comprising: a protective structure comprising a plurality of ballistic layers arranged as a stack; and an ancillary structure adjacent to the protective structure adapted to at least partly absorb a force acting on the protective structure, wherein the ancillary structure comprises at least one first layer comprising an aerogel arranged to at least partly absorb the force acting on the protective structure; and wherein a first part of each ballistic layer is moveable relative to at least one adjacent ballistic layer and wherein a second part of each ballistic layer is connected to at least one adjacent ballistic layer so as to restrict relative movement of a part of each of the adjacent ballistic layers such that the first part of the ballistic layer can move to a greater degree relative to the at least one adjacent ballistic layer compared to the second part. a protective structure comprising a plurality of ballistic layers arranged as a stack; and an ancillary structure adjacent to the protective structure adapted to at least partly absorb a force acting on the protective structure, wherein the ancillary structure comprises at least one first layer comprising an aerogel arranged to at least partly absorb the force acting on the protective structure; and wherein a first part of each ballistic layer is moveable relative to at least one adjacent ballistic layer and wherein a second part of each ballistic layer is connected to at least one adjacent ballistic layer so as to restrict relative movement of a part of each of the adjacent ballistic layers such that the first part of the ballistic layer can move to a greater degree relative to the at least one adjacent ballistic layer compared to the second part.
