摘要： Systems and methods are provided for laying up laminates. One embodiment is a method that includes laying up a multi-layer laminate of fiber reinforced material (113) onto a surface (150), by: feeding a tape (114) of fiber reinforced material (113) to tape cutters (130) which cut the tape into pieces (118), picking up pieces (118) of the fiber reinforced material (113) via pick-and-place devices at each of multiple lamination units (110) that are in sequence in a direction of travel, and placing the pieces (118) of fiber reinforced material (113) via the pick-and-place devices to form a laminate as the surface (150) and the lamination units (110) change position with respect to each other and multiple pieces (118) are laid-up concurrently.

摘要： A composite material which has excellent ballistic performance and has improved flexibility. Surprisingly, it has been found that a combination of poly(alpha-olefin) fiber and matrix resin provides these desirable product features. The resin matrix is a block copolymer of a conjugated diene and a vinyl aromatic monomer, preferably a styrene-isoprene-styrene block copolymer, that is applied as an aqueous composition. The fiber has a tenacity of at least about 35 g/d and a tensile modulus of at least about 1200 g/d. The composite has a total density equal to or less than about 100 g/m2 and a stiffness of less than about 2.5 pounds (1.14 kg) for a two layer structure of the composite, and a total areal density equal to or less than about 190 g/m2 and a stiffness of less than about 3.0 pounds (1.36 kg) for a four layer structure of the composite. The Peel Strength for a two layer structure of less than about 1.0 pounds (0.45 kg) for a two layer structure of the composite, and less than about 0.7 pounds (0.32 kg) for a four layer structure of the composite. The process of this invention permits fabrication of these desirable products in a cost-effective manner. Body armor made from the composite has improved flexibility and excellent ballistic characteristics.

摘要： A manufacturing method of composite material member includes a step of shaping a laminate including laminated prepreg sheets along a mold. The laminate includes a first layer in which fibers are oriented in single direction. In the first layer, a first surface crossing the single direction and a second surface crossing the single direction are confronted each other such that the first surface and the second surface face each other. Since the fibers are discontinuous between the first surface and the second surface, the laminate is easily shaped and wrinkles are hard to be generated in a composite material member to be manufactured from the laminate.
