US12320621 - Bulletproof shielding devices and methods

A bulletproof shielding devices and methods for protecting a user from high velocity projectiles such as bullets includes a panel having a front side and a back side. The front side is a raw carbon fiber material bonded with an epoxy resin. The back side is an extended chain polyethylene fiber material blended with the raw carbon fiber material. A bullet resistant material is positioned between the front side and the back side. The bullet resistant material includes at least four layers of an ultra-high-molecular-weight-polyethylene material. The extended chain polyethylene fiber material entangles a projectile being shot at the front side, reducing a force of an impact of the projectile and facilitating the bullet resistant material in stopping the projectile. The raw carbon fiber material exerts a force toward the projectile thereby inhibiting the progression of the projectile. The panel has a weight between 4.5 pounds and 7.5 pounds.

The patent describes a bulletproof shield assembly featuring a panel made of raw carbon fiber and extended chain polyethylene fiber, designed to protect users from high-velocity projectiles. The innovative design incorporates multiple layers of ultra-high-molecular-weight polyethylene to effectively entangle and stop incoming projectiles while maintaining a manageable weight between 4.5 and 7.5 pounds.

Claim 1

A bulletproof shield assembly comprising: a panel having a front side and a back side; the front side comprising a raw carbon fiber material being bonded with an epoxy resin; the back side comprising an extended chain polyethylene fiber material being blended with the raw carbon fiber material; a bullet resistant material being coupled to and positioned between the front side and the back side, the bullet resistant material comprising at least four layers of an ultra-high-molecular-weight-polyethylene material; wherein the extended chain polyethylene fiber material is configured to entangle a projectile being shot at the front side of the panel thereby reducing a force of an impact of the projectile and facilitating the bullet resistant material in stopping a progression of the projectile through the panel; wherein the raw carbon fiber material is configured to exert a force toward the projectile thereby inhibiting the progression of the projectile through the panel; and wherein the panel has a weight between 4.5 pounds and 7.5 pounds. a panel having a front side and a back side; the front side comprising a raw carbon fiber material being bonded with an epoxy resin; the back side comprising an extended chain polyethylene fiber material being blended with the raw carbon fiber material; a bullet resistant material being coupled to and positioned between the front side and the back side, the bullet resistant material comprising at least four layers of an ultra-high-molecular-weight-polyethylene material; wherein the extended chain polyethylene fiber material is configured to entangle a projectile being shot at the front side of the panel thereby reducing a force of an impact of the projectile and facilitating the bullet resistant material in stopping a progression of the projectile through the panel; wherein the raw carbon fiber material is configured to exert a force toward the projectile thereby inhibiting the progression of the projectile through the panel; and wherein the panel has a weight between 4.5 pounds and 7.5 pounds.
