Low Density Blasting Mat Skirt Containment

The patent changes the density parameter of the blasting mat from high-density (conventional) to low-density (new invention). The low-density mat is designed with sufficient strength and abrasion resistance to contain ejected matter from low-velocity explosions, while being significantly easier to handle and transport compared to high-density conventional mats.

The blasting mat is constructed using composite materials that provide the necessary strength and abrasion resistance without requiring high density. The mat body incorporates multiple layers including a wear layer, a reinforcement layer with cross-chorded pattern, and a base layer, creating a composite structure that achieves containment effectiveness with reduced weight.

The patent uses composite materials with multiple functional layers to achieve containment effectiveness with low-density construction. The composite structure includes wear-resistant layers, reinforcement layers with specific geometric patterns, and base layers, where each layer contributes specific properties that collectively provide adequate containment for low-velocity explosions.

Different regions and layers of the mat have different material properties optimized for their specific functions. The wear layer provides abrasion resistance, the reinforcement layer provides structural strength through its cross-chorded pattern, and the base layer provides flexibility and conformability, creating local quality variations that achieve overall containment effectiveness.
