  • Patent number: 10710327
    Abstract: A method of forming a composite article. One step involves applying adhesive on surfaces of a plurality of sublaminate units, each ply of each sublaminate unit comprising fibers impregnated with resin which has been initially cured to 30% to 50% of full cure. The initially cured sublaminate units are then arranged in a stack, which stack is pressed against a surface of a forming tool. While pressure is being applied, the stack is heated to an intermediate temperature above a glass transition temperature of the resin for a time interval sufficient to intermediately cure the resin to 50% to 70% of full cure to form a composite laminate having a contour defined by the surface of the forming tool. Then the resin is finally cured at a final temperature higher than the intermediate temperature.

    Abstract: A method for producing solidified fiber bundles includes applying a melt or solution to a carrier web forming a viscous coating, applying parallel filaments under tension to the carrier web, and pressing the filaments into the viscous coating, forming an impregnate. The coating is partially solidified until a plastically deformable state of the impregnate is obtained by vaporizing the solvent, thermal curing and/or cooling. The impregnate is rolled onto a winding core to form a roll while maintaining a winding tension of the filaments in the impregnate. The outer roll is fixed on the winding core by a sleeve and/or by adhesive tape. The impregnate is solidified by vaporizing the solvent, thermal curing and/or cooling. The solidified impregnate is divided up to form solidified fiber bundles. A pressure produced by the winding tension of the filaments in the impregnate is exerted on the roll.

  • Patent number: 9993991
    Abstract: A lightweight composite panel, and resisting to impacts and to peeling, comprising: a honeycomb core in poly(p-phenyleneterephthalamide), on either side of which are positioned two skins each comprising: an internal ply comprising: a fabric of glass fiber E in contact with the honeycomb core; and a web of unidirectional carbon fibers oriented along a first direction; an external ply, in contact with the corresponding internal ply, comprising: a web of unidirectional carbon fibers oriented along a second direction different from the first direction, the web of each external ply facing the web of the corresponding internal ply; and a fabric of glass fiber E. The fabrics of glass fiber are impregnated with at least 70% by weight of epoxy resin, and have a mass of less than or equal to 30 g/m2. The webs of carbon fibers have an elastic modulus comprised between 275 and 300 GPa, are pre-impregnated with between 30% and 40% by weight of epoxy resin, and have a mass of less than or equal to 100 g/m2.

  • Patent number: 9981692
    Abstract: An impact absorbing assembly comprises a CFRP part including a first portion and a second portion that are connected by a metal bending hinge connector. The metal bending hinge connector bends in response to an impact force being applied to the assembly to inhibit the CFRP part from cracking. The metal bending hinge connector may be a tubular member that defines an opening extending from a first end to a second end of the tubular member. The tubular member receives the first CFRP part in the first end and the second CFRP part in the second end. The impact absorbing assembly may be, for example, a longitudinally extending rail or a sub-frame arm.

  • Patent number: 9919785
    Abstract: A stringer made of composite material for reinforcing aircraft skin panels. Plies are introduced at 90° in a segment close to the stringer run-out, and progressively reducing the number of plies at 0°, such that the majority of the number of plies is at 90° in an segment adjacent to the run-out, so the stiffness of the run-out is reduced, and the load it supports is also therefore reduced. This is an alternative solution to the solutions already existing for getting the stringer run-outs to support a smaller load, thereby reducing both the risk of the plies of the stringer peeling off and the risk of separation between stringer and skin panel. A method of manufacturing said stringer is also provided.

  • Patent number: 9918559
    Abstract: By taking into account the difficulty in smoothly bending along the shape of, for example, a care bed, there is provided a three-dimensional net-like structure made from polyethylene having a swelling ratio dependent on a shear rate such as to be 0.93 to 1.16 at a shear rate of 24.3 sec?1 and 1.15 to 1.34 at a shear rate of 608 sec?1 and having an MFR of 3 to 35 g/10 min and a density of 0.82 to 0.95 g/cm3 and configured to have a spring structure of filaments randomly brought into contact with and tangled with one another, have a three-dimensional striped sparse-dense configuration in a lateral direction relative to an extrusion direction. The swelling ratio is shown as D2/D1 against shear rate when a molten thermoplastic resin is extruded to filaments from a capillary having a tube inner diameter D1 of 1.0 mm and a length of 10 mm and D2 denotes a diameter of cross section of the filaments extruded and cooled down.

  • Patent number: 9895849
    Abstract: A method of manufacturing a wind turbine blade using pre-fabricated stacks of reinforcing material is described. The stacks 14 comprise a plurality of plies of fiber material, joined together along a side edge to form a spine. The opposite edges of the stack are left unjoined so that the plies can separate and slide across one another. In doing so, the stacks can be stored flat, but on installation into a curved mold 12 profile, the plies may slide to adopt the curved shape of the mold. The stacks extend from a point near the leading or trailing edge of the mold to an intermediate point on the mold surface. The stacks may be used to construct the thickened root section of a wind turbine blade.

  • Patent number: 9833933
    Abstract: The present invention relates to a method of manufacturing a body made of composite material such as a shell of a helmet. Said body constitutes a multilayer structure where each layer is formed by superposed strata comprising portions of fabrics preimpregnated with thermoplastic resin in which at least some of said layers are formed by woven or non-woven LFRTP-type preimpregnated fabrics. The outer layer is formed by strata of portions of “veil” type or “felt” type fabrics, with non-woven and non-oriented fibers of lengths comprised between 5 and 20 mm. In the method, the multilayer structure arranged in a mold is subjected to the action exerted by a bag that is inflated due to pressure occupying the cavity of the mold.
