Title: Charles M Roland: Innovator in Advanced Armor Solutions

Introduction

Charles M Roland is a prominent inventor based in Waldorf, MD. He has an impressive portfolio of 25 patents, showcasing his innovative contributions to the field of materials and armor systems. His work primarily focuses on enhancing protective solutions for military and civilian applications.

Latest Patents

One of Charles M Roland's latest patents includes a groundbreaking invention of polymer coatings with embedded hollow spheres. This lightweight armor system provides both blast protection and ballistic protection against small arms fire. It is designed for use in helmets, personnel, or vehicle protection, as well as other armor systems. The innovation features a hard substrate coated with a thin elastomeric polymer layer, which encapsulates hollow ceramic or metal spheres. This specialized coating can serve as stand-alone blast protection or augment an underlying structure. Notably, the glass transition temperature of the polymer is ideally between negative fifty Celsius and zero Celsius.

Another significant patent pertains to a porous refractory armor substrate. This invention comprises composite armor systems that include substrates capable of delaying and reducing compressive waves resulting from ballistic impacts. These waves can reflect off the back surface of ceramic front face armor as tensile waves, potentially damaging the material. The innovative use of syntactic substrates backed by high-strength fiber enhances mass efficiency and mitigates blunt force trauma during ballistic events.
