The present invention provides an improved fiber-reinforced article comprised of at least two plies. Each of the plies comprises (a) rubber and (b) cord made from melt-spinnable, non-metallic, multifilament fibers for which the cord has a twist multiplier of less than or equal to about 375, a stress at 1% strain greater than or equal to about 1.7 grams/denier, and an initial compressive modulus greater than or equal to about 7 grams/denier, and the at least two plies have a fiber orientation angle of greater than or equal to about 23&#xb0;. The composite is useful as a tire belt in a passenger tire.

Composite comprising organic fibers having a low twist multiplier and improved compressive modulus

A rigid improved penetration resistant composite of the type comprising a plurality of fibrous layers comprising network of fibers in a polymeric matrix selected from the group consisting of thermoplastic polymers, thermosetting resins or a combination thereof, at least two of said layers secured together by a securing means, said improvement comprising a securing means which comprises fiber stitches wherein the average stitch length is greater than the average stitch path, a process for forming the composite and articles fabricated from said composite.

Constructions having improved penetration resistance

A composition containing a matrix, a fiber, a filler; and a friction modifier; wherein an effective amount of at least one of said components selected from the group consisting of fiber, filler, friction modifier and combinations thereof are cure promoting compounds having an effective aspect ratio such that the composition is rapidly cured in the presence of electromagnetic energy, and a process for curing such compositions. Articles comprised of this composition are suitable for use in the production of friction materials, such as brake pads, drum linings, and clutches.

Composition for use in friction materials and articles formed therefrom

An improved rigid composite of the type comprising a plurality of fibrous layers at least two of which are secured together by a securing means, said improvements comprising a securing means which comprises at least two adjacent paths.

This invention relates to a fire resistant multilayer complex ballistic resistant article comprising at least one first layer comprised a plurality of flammable fibers a first matrix and at least one second layer which is adjacent to said first layer which comprises a plurality of fire resistant fibers in a second matrix, wherein the second matrix comprises a fire retardant material and is different from the first matrix material.

Fire resistant ballistic resistant composite armor

The present invention relates to high strength, high modulus polyethylene filaments which form composites having improved shear strength and composites formed from said filaments.

Rigid polyethylene reinforced composites having improved short beam

This invention is related to a woven fibrous article which exhibits relatively low reductions in energy-to-break and tenacity on repeated impacts.

Impact resistant woven body

This invention relates to a fire retardant compound comprising at least one fibrous layer comprising a network of fibers such as high strength polyethylene or aramid fibers in a matrix such as a blend of a vinyl ester and a polyurethane, and a fire retardant layer comprised of a particulate fire retardant material which decompose an heating to a gaseous material such as magesium hydroxide dispersed in a matrix comprised of relatively high char yield resin such as cured phenolic cyanate resin.

Flame resistant ballistic composite

The present invention provides an improved composite which comprises one or more layers, at least one of said layers comprising network of high strength filaments having a tensile modulus of at least about 160 grams/denier, a tenacity of at least about 7 g/denier and an energy-to-break of at least about 8 joules/gram in a matrix material, the ratio of the thickness of said layer to the equivalent diameter of said filaments is equal to or less than about 12.8, and complex composite articles formed from said composite.

Ballistic-resistant composite article

Polyacrylonitrile (PAN) fibers are prepared by forming a 2-15 weight % solution of PAN of M.sub.w at least 500,000, extruding, cooling to below the gel temperature, extracting and drying. At least one of the gel fiber, the fiber containing extraction solvent and the dried gel is stretched. The product PAN fibers have a M.sub.w at least 500,000 (e.g. 1,000,000-4,000,000 or 1,500,000-2,500,000), a tenacity at least 5 g/den (e.g., at least 7 g/den) and a secant modulus at least 100 g/den (e.g. at least 125 g/den).

Method for preparing tenacity and modulus polyacrylonitrile fiber

Polyvinyl alcohol of molecular weight over 500,000 (i.e. 1,500,000 to 2,500,000) is spun as a dilute solution (2-15%) in a relatively non-volatile solvent such as glycerin. The resultant gel fiber is extracted with a volatile solvent such as methanol and dried. Upon stretching at one or more stages during the process, fibers of tenacity above 10 g/denier and modulus above 200 g/denier (e.g. 18 and 450, respectively) are produced.
