Armor

BTG Research can quickly, accurately and economically conduct ballistic and laboratory scale blast tests of candidate armor materials and components, whether developed in-house or by outside vendors. In addition to determining V50 and similar tests according to NIJ standards, capabilities include determining projectile velocity, force, and energy transfer as well as backface deformation in armor. BTG Research can also advise on quantitative analysis of video data you may already have.

NEW! Request for Data NEW!

For law enforcement agencies in the United States, we will consider requests to provide brief, no cost reviews of available test data to better inform decisions regarding armor selection. We may also be able to provide a modest amount of armor testing at no cost for samples provided by law enforcement agencies. Contact us to make a request or discuss possible testing.

 Ballistics testing

  • V50 and related armor tests can be performed using projectiles up through .50 cal, including .30 cal AP. BTG Research has knowledge and experience with a wide range of projectiles and loads. Custom loads can be developed to meet experimental requirements.

  • Beyond basic penetration data, post-penetration velocity, energy transfer, accelerations, and force of resistance can often be determined in conjunction with high speed video data.

  • These methods are applicable both to vehicle and structural armor as well as hard or soft personal protective equipment (PPE).

  • Ballistic testing can be conducted with 10% gelatin (FBI specification) or clay (NIJ Standard 0101.06).

Laboratory scale blast testing

  • Using oxy-acetylene driven shock tubes developed at BTG Research, the blast wave transmission, reflection, and absorption of materials and structures can be quantified.

  • In combination with high-speed video analysis, similar tests can be performed to determine momentum transfer and compare the response of candidate materials or designs.

  • With these methods, effects of different geometric designs on blast transmission can also be quantified.

Acoustic impedance

  • Non-destructive speed of sound measurements can be made for candidate armor materials and structures. These measurements can inform numerical simulations and decisions about layering materials for optimal ballistic and blast resistance.
