Abstract

An article of armor. The article has a composite article with an exposed edge and a wrap layer wrapped around at least a portion of the exterior surface of the composite article and around at least a portion of the exposed edge. The article of armor may be a helmet.

Description

    CROSS REFERENCE TO RELATED APPLICATIONS
  • This application claims priority to U.S. Provisional Patent application 61/812,074 filed Apr. 15, 2013, which is incorporated herein by this reference.
    • TECHNICAL FIELD
  • This disclosure relates to protective equipment and personal armor; more particularly it relates to layered armor and composite wrapped configurations
    • BACKGROUND
  • In the manufacturing of composites it is desirable to cut the material so that mechanical properties are not diminished or interrupted. When a fabric is formed into a shape such as a helmet, there is a wrinkling of the fabric (such as the wrinkles in a cupcake paper cup) before the fabric is cut. This allows for increased mechanical and ballistic resistance due to the continuous fibers, but has two drawbacks.
  • 1) the slight visual appearance of wrinkles may be undesirable to some customers.
  • 2) There is an end grain to all composites when cut at the edge of a part, and this end grain is weaker and must be covered with some kind of edge trim.
    • DISCLOSURE
  • The solution presented solves one or both of these problems.
  • A composite article, in particular a helmet, is formed from desired composite materials or a hybrid of materials, and is then cut to the desired shape leaving an exposed edge. The composite part is then wrapped in a fabric of secondary fiber (can be any fabric or fiber, including without limitation Kevlar, carbon, or cotton). A spray adhesive can be used to assist in wrapping the part. In particular the exposed edges are wrapped with the secondary fiber. The secondary fiber can be a pre-impregnated fiber with resin already in it (either thermoset or thermoplastic), or it may be dry with a wet resin system applied to it by hand.
  • Once the wrapping composite and resin are applied to the part, it is placed in a match metal die system and closed. This forms the outside fabric and the part to a seamless smooth aesthetically appeasing finished shape. The final match metal die may be heated and cooled and have any number of conventional systems included, such as ejection systems.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is a schematic illustration of the disclosed configuration.
    •  DETAILED DESCRIPTION
  • In FIG. 1, wrap layer 30 is wrapped around all or a portion of composite armor 10. Armor 10 has inner portion 20 and end portion 5. Wrap layer 30 is desirably wrapped around end portion 5.

Claims (3)
