Structural Armor

Structural Armor

Structural armor solutions are designed to be capable of withstanding structural loading in addition to resisting hostile actions. This allows designers to use armor panels directly as construction elements in shelters, building or on vehicles.


Composhield has developed and maintains three types of structural armor technologies, each tailored to meet a specific application area: non-mobile, semi-mobile and mobile.

Composhield offer several Structural Armor solutions


Non-Mobile applications include permanent structures such as embassies, power plants or military headquarters that would be a prime target for hostile actions. The main threat to consider here are very large explosive charges – several hundred kilograms of TNT.

Composhield has developed and patented a unique technology for such applications: High Impact-Resistant Composite, or HIRC. products based on HIRC technology are extremely resistant to blast loads and can effectively protect permanent installations with very moderate space claim.

The technology is based on a UHSS rebar pattern, laced with high-strength aramid fibers, that are embedded in a special cementitious matrix. Together this form a panel that exhibits very high-strength properties while being very ductile. This allows a HIRC panel to absorb large quantities of energy without breaking up or loosing structural integrity.

Composhield has developed and patented a unique technology for semi-mobile applications: Steel-Concrete composite, or SC. The system uses a mix of HHA steel, HH steel and a reinforced cementitious matrix to create an armor panel that:

  • Has excellent resistance to blast loading
  • Provides ballistic protection up to STANAG 4569 Level 3
  • Provides protection against fragmentation

The SC technology is heavier, for the same threat, than our mobile CP technology, but provides protection at a lower cost. This renders the technology ideally suited for protection larger structures where mass is not the most critical factor.

Composhield structural armor for mobile applications is based on high­-strength and high-stiffess composite materials that incorporates ballistic properties. The armor component is derived from our Ceramic PoIymer (CP) technology, which is also used for add-armor.

For mobile applcations the CP armor is reconfigured to better carry and absorb structuraI loads, whereby the armor panels themselves can be used as structuraI elements for sides, doors, hatches etc., while still providing ballistic protection.

Key benefits are:

  • Ballistric performance up to STANAG 4569 Level 4

  • Protection against fragments from mortars and artillery shells

  • High structural stiffness and strength

  • Excellent multi hit capabilities

  • Good resistant to blast loading

This minimizes the overall mass of the armor system, as no material is wasted on redundant system components. This renders the CP structural armor ideal for applications, where little mass and space is available.
