Crumb rubber obtained from recycled tires is subjected to an interlinked substitution process. The process utilizes a reactive component that interferes with sulfur bonds. The resulting treated rubber exhibits properties similar to those of the virgin composite rubber structure prior to being granulated, and is suitable for use in fabricating new tires, engineered rubber articles, and asphalt rubber for use in waterproofing and paving applications.

A prepreg having high processability and laminating performance and a method to produce such a prepreg is described, the prepreg comprising at least the components [A] to [E] shown below, and having a structure incorporating a first layer composed mainly of the component [A] and a first epoxy resin composition that contains the components [B] to [D] but which is substantially free of the component [E], and a second layer composed mainly of a second epoxy resin composition that contains the components [B] to [E], [A] carbon fiber, [B] epoxy resin, [C] curing agent, [D] thermoplastic resin, and [E] particles containing a thermoplastic resin as primary component and having a volume-average particle diameter of 5 to 50 ?m.

A laminate assembly includes a matrix layer and elongated, continuous strips of a conductive alloy. The matrix layer has opposite first and second sides connected by opposite first and second edges. Each of the first and second edges extends from the first side of the matrix layer to the opposite second side of the matrix layer. The elongated, continuous strips of the conductive alloy are disposed in the matrix layer between the first and second sides of the matrix layer. The elongated continuous strips continuously extend through the matrix layer from the first edge to the opposite second edge.

Square symmetric composite laminate structures, and sub-modules thereof, are provided, along with methods of forming the same. The square symmetric laminate structures include two or more sub-laminate modules, each comprising: a first ply set consisting of a first ply layer oriented at a first angle and a second ply layer oriented at a second angle, a first sum of the first and second angles being ninety degrees; and a second ply set consisting of a third ply layer oriented at a third angle and a fourth ply layer oriented at a fourth angle, a second sum of the third and fourth angles being ninety degrees; wherein the second ply layer is positioned adjacent the third ply layer and the second and third ply layers are both positioned intermediate the first and fourth ply layers, thereby defining a double-double helix arrangement of the respective ply layers. Associated methods are also provided.

A construction product described herein includes a fiber core that includes a plurality of entangled glass fibers. The fiber core also includes a binder that bonds the plurality of entangled glass fibers together and an Aerogel material that is homogenously or uniformly disposed within the fiber core. In some instances, the fiber core includes between 40 and 80 weight percent of the Aerogel material. The construction product has an R-value of at least 6.5 per inch, a flame spread index of no greater than 5, and a smoke development index of no greater than 20 as measured according to the ASTM E-84 tunnel test.

An acoustic insert comprises a sleeve having a first end and a second end. The sleeve comprises segments between the first end and the second end. A first acoustic septum is placed within the sleeve at a first depth. A second acoustic septum placed within the sleeve at a second depth.

Improvement in a ballistic resistant material is disclosed. The material uses unidirectional laid aramid of fibers that. The fibers are laid in a unidirectional arrangement that allows the fibers to essentially nest together to create a more dense and thinner material. The fibers can be different and can include fiberglass to graphite or any combination of fibers or alloys that the application requires including electrically conductive and non-electrically conductive, flammable and non-flammable, water restraint to non-water restraint, buoyant and non-buoyant materials. The material is bonded with NANO technology that fills in the gaps in the molecular structure of the adhesives that can contain petroleum and nonpetroleum based adhesives depending on the application.

The embodiments described herein provide for composite panels that include elements that form one or more Radio Frequency (RF) antennas. The composite panels may be integrated along with other composite panels to form a composite structure for a vehicle. In some cases, the composite panels function both as elements of an RF antenna and as structural elements of the vehicle. In some cases, the composite panels function both as elements of an RF antenna and as a means for static charge dissipation. When operating as an RF antenna, the composite panels are inherently conformal with an outside surface of a composite structure.

An insulative construction product includes a polyurethane foam core and a mixture of Aerogel and carbon black that is disposed within the polyurethane foam core. The mixture of Aerogel and carbon black includes between 90 and 99 weight percent Aerogel and between 1 and 10 weight percent carbon black. The polyurethane foam core includes between 10 and 90 percent by volume of the of Aerogel and carbon black mixture and the construction product has an R-value of at least 8.0 R/inch.
