Materials including support layers and fiber-free compositions are disclosed, as well as related articles and methods for making the materials. The fiber-free compositions compositions are formed from a precursor composition that includes a nitride butadiene rubber, a nanoclay and a cure package including a sulfur-based curing agent. The fiber-free compositions may have a substantially reduced weight and compressive modulus in comparison to conventional rubber. Thus, the fiber-free compositions may provide improved ballistic properties in addition to reduced density and thickness. Precursor compositions for forming the insulative composition may have good flow characteristics. The fiber-free compositions may be used in a variety of applications, such as personnel body armor, ground vehicle armor and aircraft armor systems.

In at least one embodiment, a molding method for producing a molded article is provided. The method may include introducing polymer and fiber separately into an extruder in a first ratio to produce a first extruded material having a first fiber content and in a second ratio to produce a second extruded material having a second fiber content different from the first fiber content. The method may further include filling a first region of a mold with the first extruded material and a second region of the mold with the second extruded material. The extruded material may be formed as blanks for use in compression molding or may be introduced into an injection chamber for use in injection molding. The method may be used to form molded articles having a plurality of regions having different fiber contents.

Precursors, insulative compositions, an article including the insulative compositions and a method for making the insulative compositions are disclosed. The insulative compositions are formed from a precursor composition that includes a nitride butadiene rubber, a nanoclay and a cure package including a sulfur-based curing agent. The insulative compositions may have a substantially reduced weight and compressive modulus in comparison to conventional insulative rubbers. Thus, the insulative compositions may provide improved ballistic properties in addition to reduced density and thickness. Precursor compositions for forming the insulative composition may have good flow characteristics. The insulative compositions may be used in a variety of applications, such as personnel body armor, ground vehicle armor and aircraft armor systems.

This invention is directed to a rifle barrel and a method for modifying a pre-existing rifle barrel comprising dissembling said pre-existing rifle so that said barrel is removed from said pre-existing rifle placing said barrel in a sleeve having an inner diameter larger then said diameter of said barrel for receiving said barrel thereby defining a void arranged between said barrel and said sleeve when said barrel is placed in said sleeve reducing the outer diameter of said barrel near the breach end of said barrel so that said sleeve will cover said barrel up to the action of said rifle when said barrel is placed in said sleeve filling said void defined by said barrel and said sleeve with filler material attaching a weld-on thread assemble to said sleeve at the muzzle end of said barrel and assembling said pre-existing rifle with said barrel placed in said sleeve.
摘要:
The present invention concerns a method of producing a moulded mineral wool insulation product, said method comprising the steps of providing a mixture by mixing mineral fibres with a binder composition, and providing said mixture in a mould form, and then curing the binder, wherein the binder composition comprises at least one hydrocolloid, and then removing the moulded product from the mould form.
摘要:
A fiber product is described which includes fibers, a binder and a temperature control additive. The fiber product has properties that make it useful for a variety of applications. The fibers may be glass fibers and the product may be a fiberglass insulation product for use in buildings, vehicles, or other structures for acoustic and/or thermal insulation. The fibers may be cellulosic fibers and the product may be a wood board product. The temperature control additive is incorporated into the uncured fiber product to prevent deleterious self-heating during or after binder curing. The temperature control additive undergoes an endothermic process that consumes at least a portion of the energy generated during the exothermic curing reaction.
