sp2nano is about Solving Problems to increase effectiveness of men and materials
The U.S. Army should authorize commanders to allow combat troops to leave the service's heavy, over-designed body armor behind on certain missions to increase physical performance, according to a new report from the Center for a New American Security.
"Body armor provides increasingly advanced protection, but at a cost in soldier performance," according to "The Soldier's Heavy Load," part of the "Super Soldiers" series of reports that Army Research Laboratory commissioned CNAS to conduct looking at soldier survivability.
"Increased soldier load not only slows movement and increases fatigue, but also has been experimentally demonstrated to decrease situational awareness and shooting response times," the report added.
sp2nano does not sell armor, rather we are a Business to Business Organization that manufactures and sells reinforced fabric for armor to the manufacturers of armor that will enable the production of lighter and more effective armor. Our product is based on the most common ballistic fiber used today poly-para-phenylene terephthalamide; commercially know as Kevlar (DuPont) and Tarwon (Tejin). If you have an interest in a different fiber material please inquire. We are capable of working with all weaves and fabric weights, woven and nonwoven and work with our customers to optimize their product.
Hard Armor Composites, as opposed to soft armor, are made with a matrix resin that provides a rigid product. Our functionalized fabrics will make stronger products because the functionalized fabric and nanocarbons will chemically bond to the matrix resin. Our Armor reinforced fabrics are designed for helmets and armor plates. These materials are often used in conjunction with thin ceramic plates.
Advanced Composites are made from Carbon Fibers and Glass Fibers as well as Kevlar. These materials have already made Aircraft and Sporting Goods lighter and more effective. Our technology is more correctly described as Advanced Hybrid Hierarchal Nano Composites that is comprised of microscale fibers and nanoscale carbon materials. Materials that meet this definition are currently taking their place in developing Advanced structural Composites by reinforcing the matrix resin in the composite system. sp2nano 's emerging technology surpasses this application developed by chemically attaching functionalized reactive groups to the fabrics and fibers. These reactive sites provide an anchor for grafting reinforcement to the fibers and fabrics creating a much stronger bond between the reinforcement and the matrix resin which provides stronger structure. In past research other means of noncovalently placing graphene oxide and carbon nanotubes on carbon and Kevlar fabrics have been reported. These methods set the nano materials into the tow or wrapped the materials around the fibers. Substantial improvement in interlaminar shear strength and compression failure after impact has been reported in these studies.
Our technology amplifies these properties. Graphene, carbon nanotubes and graphene nanoribbons that are bonded to the fibers that make up the fabric providing a unified composite structure. We also have the ability to customize the mechanical properties by mixing the carbon materials that we attach to the fabric. It is well known that these carbon nanomaterials act synergistically when paired to increase the composites properties. Our product will also eliminate the problem faced by manufacturers of composite parts related to even dispersion of the nano reinforcement in the finished composite. The nanomaterials added to the resin measurably increases the viscosity of resin requiring much higher pressure to produce the part; and forcing the filled resin through the reinforcing fabric filters the nano reinforcing filler. Not only does our product make the part lighter and stronger it also improves process and quality.
Our principal goal is to remove the Achilles Heel that plagues laminar composite materials-Low Interlaminar Shear Strength and Delamination After Impact! Our current development effort is to make these Anisotropic Structures (High strength in X and Y axis with very limited strength in the Z axis) Isotropic Structures (High strength in all axes). We will do this by tying the laminate plies together with the strongest known materials-Graphene and Carbon Nanotubes. As discussed earlier Graphene Nano Ribbons can be economically produced by unzipping the carbon nanotubes. We currently produce fabric that has very long carbon nano ribbons (100-200 microns) grafted onto it, and these nanoribbons are functionalized for further reaction potential. This length and reactivity allow us to join adjacent plies with compatible chemistry. This will eliminate the prevalent Advanced Composite issue that could adversely impact these materials suitability for the automotive applications market. This product has been developed specifically for the next generation of automobiles.
sp2nano HEM incorporates hybrid electronic materials developed with both traditional materials and materials derived from the graphene family. A past venture of Mr. Craig, Polymeric Interconnect Inc's (PII) product portfolio was acquired by Dow Corning in 2004. PII developed and produced Electronic Interconnects based on conductive inks and adhesives for circuit boards, RFID tags, solar cell contacts and other electronic materials applications. Although the products acquired by Dow Corning were not commercialized, fifteen years later they still outperform the products in use for these applications today. These current silver conductive ink products cost in excess of $1000/Kilo.
Due to major emerging markets driven by Printed Electronics, alternative energy, 5 G communications, and the Internet of Things the market opportunity for these conductive materials will explode. We view our opportunity in this market as providing a lower cost solution by utilization of lower cost carbons in conjunction with expensive silver.
sp2nano is currently developing conductive inks and adhesives for these applications that will be snap cure at moderate temperature for applications in Printed Electronics, RFID antennae, and in mold circuitry. Flexible and stretchable products will be developed for applications in wearables and smart clothing that will include sensors.
The market for Electronic Materials is being seriously impacted by these new graphenic materials with massive market developing for displays, batteries and capacitors to only skim the surface. Where we see disruptive opportunities that match our capability we intend to participate in this opportunity.
