Definitions

  • This invention relates to articles which are laminates of fiber-reinforced polymeric composite layers. Specifically, the invention relates to articles which have at least two composite layers in which the fiber reinforcement is oriented obliquely with respect to the longitudinal axis of the article and which fiber is not cut in the manufacture of the article but rather, is continuous in the cross-plied laminate article. In addition, a method is disclosed to make such a laminate article continuously.
  • Laminates of unidirectional fiber-reinforced polymeric composite sheets are well known in the art and have a diverse array of uses. For instance, such laminates find use as components of: ballistic-resistant articles, tires for vehicles, conveyor belts, and mailing packages.
  • the types of fibers and polymers used in the manufacture of such fiber-reinforced sheets are also quite diverse and are typically chosen with consideration to the desired end use for such articles.
  • These laminated articles are commonly stacks of unidirectional fiber-reinforced composite panels in which the fiber in adjacent stacked panels has an equal and opposite fiber orientation angle with respect to the longitudinal axis to provide balanced reinforcement.
  • the composite panels are then made to adhere to one another, for example, by curing of the polymeric sheet material by application of pressure and heat.
  • U. S. Patent 5,535,801 discloses a tire belt which is a multiple layer folded laminate of continuous, unidirectional fiber-reinforced material.
  • the tire belt is made of a narrow, tire cord-reinforced ribbon, preferably 5 to 15 mm wide, which is spirally zigzagged to create the tire belt.
  • the preferred cord for reinforcement is aromatic polyamide. This design is advantageous in having no cut fibers at the longitudinal edges of the belt.
  • folding the narrow ribbon into the desired zigzag design involves extensive manipulation of the ribbon and would likely be time-consuming if such a technique was used to generate much longer lengths of a multiple layer laminate.
  • the composite has a large number of joints of abutted or slightly overlapped edges in each layer of the laminate.
  • the frequency of joints may be disadvantageous in some uses of such a composite.
  • a similar zigzag composite is also disclosed in U. S. Patent 5,427,167.
  • U. S. Patent 5,766,725 discloses a single layer composite web of parallel fibers in a matrix in which the fibers in the composite layer run at an angle differing from 0° relative to the lengthwise direction of the web.
  • the linear structure of the composite web is a series of joined-up and connected web parts which parts are obtained by cutting them out of a web having unidirectional fibers which are parallel to the longitudinal axis of the web. The cutting is angled with respect to the longitudinal axis and the cut parts are joined-up and connected in such a way that the cut sides form the longitudinal sides of the composite web.
  • this composite web contains cut fiber ends along the entirety of its two parallel longitudinal sides. A method of making this composite web is also disclosed.
  • the method involves multiple steps including cutting out of the web parts and assembly of web parts into the single layer composite web having fibers running at an angle differing from 0° relative to the lengthwise direction of the web.
  • To form a multiple layer composite one then takes this single layer composite web and assembles it with another layer of web to form a two layer composite, for instance.
  • This method thus involves cutting and multiple assembly steps to yield at least a two layer composite and the resultant composite has at least one layer containing cut fibers.
  • the problem to be solved is therefore a laminate article in which unidirectional, parallel fibers embedded in a matrix are oriented at greater than 0° with respect to the longitudinal direction of the composite and are cross-plied with respect to an adjacent layer.
  • each of the layers comprises a plurality of units of unidirectional, parallel fibers embedded in a polymeric matrix, each of the units having a width of at least about 7.5 inches (about 191 millimeters), the fibers are essentially continuous within the at least two layers and the fibers have a fiber orientation angle of between 0° and 90° with respect to the longitudinal direction of the laminate article.
  • a method to manufacture the inventive laminate article is also taught.
  • Preferred fibers are extended chain polyethylene fibers and polyethylene naphthalate.
  • Figure 1 illustrates a cross-plied laminate article of the invention and its hollow tube predecessor.
  • Figure 2 shows the spirally-wound hollow tube of Figure 1 hypothetically cut along a line parallel to the longitudinal axis of the tube relationships and opened flat to show a planar shape.
  • Figure 3 is a partial plan view of an article comprising a cross-plied laminate of the invention, with the layers partially removed to show the next adjacent layer.
  • Figure 4 illustrates a method useful in making the cross-plied laminate article of the invention.
  • essentially continuous means fiber, yarn or cord which has a length greater than the length of the cross-plied laminate article of the invention and substantially greater than the width of the cross-plied laminate.
  • each strand of fiber reinforcement has only two cut ends in the entire length of the cross-plied article, and such cut ends are not located at the longitudinal edge of the inventive article.
  • Staple fiber is thus not part of this invention, per se, but is included to the extent that it forms part of a continuous spun yarn.
  • fiber orientation angle refers to the acute angle formed between the longitudinal axis of the unidirectional fiber and the longitudinal axis of the cross-plied laminate.
  • fiber is an elongated body, the length dimension of which is much greater than the transverse dimensions of width and thickness. Accordingly, the term fiber includes monofilament, multifilament fiber, ribbon, strip, a plurality of any one of combinations thereof and the like having regular or irregular cross-section. The term fiber includes therefore twisted or untwisted yarns of a plurality of filaments and twisted or untwisted cords made from such yarns. Fiber also includes continuous spun yarns formed from staple fiber.
  • unidirectional fibers refers to the fibers used to reinforce the matrix material and how the fibers are arranged within the matrix. Unidirectional fibers are arranged in a substantial parallel fashion and thus are not crossed by other fibers within essentially the same layer of matrix material.
  • ply refers to a single layer in the laminate article of the invention.
  • a ply may be continuous or non-continuous with any other ply in the inventive article. If the inventive article is made with a sheet of fiber-reinforced material helically wrapped singly around a mandrel roll, it will be a two-ply laminate and the two plies are continuous with each other. If the inventive article is made with two or more adjacent sheets of fiber-reinforced material helically wrapped in a single layer around a mandrel roll, it too will be a two-ply laminate, however the two plies are not necessarily continuous with each other. If the inventive article is made with more than one sheet wrapped in more than one layer around the mandrel roll, the resultant laminate will be four ply or more and some plies will not be continuous with other plies.
  • cross-plied laminate and "cross-plied article” as used herein refers to an article having two or more layers of fiber-reinforced material.
  • cross-plied article of the invention the longitudinal axes of fibers of the adjacent layers are rotated relative to one another.
  • cross-plied article of the invention formed by wrapping more than one layer on the mandrel roll, only the two central adjacent layers have fiber longitudinal axes rotated relative to one another.
  • Fibers for use in the practice of this invention may be metallic, semi- metallic, inorganic and/or organic.
  • Useful fibers include polyolefin based polymers and particularly ultra high molecular weight polyolefin fibers including polyethylene and polypropylene fibers.

  • the matrix material can comprise one or more thermosetting resins, or one or more thermoplastic resins, or a combination thereof.
  • thermoplastic resins are resins which can be heated and softened, cooled and hardened limitless times without undergoing a basic alteration
  • thermosetting resins are resins which do not tolerate thermal cycling and which cannot be resoftened and reworked after molding, extruding or casting and which attain new, irreversible properties when once set at a temperature which is critical to each resin.
  • the key requirement of the matrix material is that it be flexible enough to process with the inventive method to generate the inventive laminate article. Choice of an appropriate matrix material would be obvious to one of ordinary skill in the art.

  • the fiber-reinforced composite which is used to form the laminate article of the invention is formed by conventional methods for embedding fibers in matrices or impregnating fibers with matrix material.
  • the matrix material/fibers combination is then consolidated which means that the matrix material and the fiber are combined into a single unitary layer. Consolidation can occur via drying, cooling, pressure or a combination thereof.
  • Fiber-reinforced rubber used in the formation of tire belts can be prepared as taught for instance in commonly-assigned, filed concurrently herewith pending application to Socci et al.
