- the present invention relates to a thin layer reinforcing material that reinforces mechanical properties of a substrate to be reinforced that is lightweight, thin, and flexible.
- Patent Document 1 a tape formed by impregnating a carbon fiber or the like directly into a matrix as a thermosetting resin or a thermoplastic resin has been widely used as an intermediate material for composite materials.
- Molded articles made using such an intermediate of a normal fiber reinforced polymer composite material are characterized by being rigid for high weight and having high mechanical properties. It has been developed for various uses.
- Patent Document 1 Japanese Patent Laid-Open No. 2003-165851
- Patent Document 2 International Publication No. 2005Z002819 Pamphlet
- the conventional fiber reinforced polymer composite material can obtain high mechanical properties, but it is difficult to combine the high mechanical properties with thinness and flexibility. . Therefore, a conventional composite material intermediate cannot be used as a reinforcing material that reinforces mechanical properties while retaining the properties of a thin layer substrate that is lightweight and flexible.
- a sail of a sailing ship is cited as an example that needs to have high mechanical properties such as tear strength while maintaining the lightness, thinness, and flexibility of the base. Et It is.
- the sail of a sailing ship is a force racing cloth that has been a preferred material.
- For sailing sailboats it is necessary to extract the maximum boat speed under the wind of various conditions.
- On the other hand in addition to its shape, it is required to be lightweight, to have high tear strength, and to have sufficient flexibility and resistance to refraction.
- the thickness of the sail increases, the weight increases, and flexibility and folding resistance are impaired.
- the reinforcing fiber is often used more than necessary, the cost is increased accordingly.
- a reinforced substrate having a thin, lightweight, and flexible characteristic is characterized by its thickness, weight, flexibility, and the like.
- the object is to provide a thin-layer reinforcing material with improved mechanical properties while maintaining the above.
- a thin layer reinforcing material according to the present invention is a thin layer reinforcing material that is bonded to a substrate to be reinforced to reinforce the mechanical properties of the substrate,
- the reinforced fiber single yarn bundle that has been spread and widened so that the width of the fiber becomes 1.3 mm or more is also obtained by impregnating with an adhesive resin.
- the reinforced substrate is lightweight, thin and flexible.
- the mechanical properties of the reinforced substrate can be improved while maintaining the characteristics of the reinforced substrate that are lightweight, thin and have more flexible characteristics.
- the substrate to be reinforced is a sheet-like body.
- the mechanical properties can be improved while maintaining the properties of the sheet-like reinforced substrate that is lightweight, thin, and flexible.
- the adhesive resin is a hot melt type resin.
- the thin layer reinforcing material can be bonded to the reinforced substrate by thermocompression bonding.
- the thin layer reinforcing material of the present invention is one in which a release tape is bonded to at least one surface of the thin layer reinforcing material.
- the thin layer reinforcing material can be spread and stored, so that the storage method becomes simple and the thin layer reinforcing material is also treated when it is bonded to the substrate to be reinforced. Easy to do.
- the reinforcing fiber is a carbon fiber.
- the mechanical properties of the thin-layer reinforcing material can be efficiently enhanced by the high specific strength and specific elastic modulus of the carbon fiber.
- the thin-layer reinforcing material of the present invention is such that the reinforcing fibers are arranged in a uniaxial direction in the layer of the reinforcing fiber single yarn bundle.
- the thin-layer reinforcing material of the present invention is the same as the thin-layer reinforcing material in the arrangement direction of the reinforcing fibers.
- the thin-layer reinforcing material of the present invention is the same as the thin-layer reinforcing material in the arrangement direction of the reinforcing fibers. It is affixed on the reinforced substrate so as to face different directions. This makes it possible to improve the mechanical characteristics of the reinforced substrate in a plurality of directions without greatly changing the characteristics such as weight and thickness of the reinforced substrate.
- the main component of the substrate to be reinforced is a biaxially stretched film.
- an airtight, lightweight, thin and flexible reinforcing body can be provided more easily.
- This reinforcement is particularly suitable for sail materials.
- the thin-layer reinforcing material of the present invention is a laminate of a printed film on one surface of the thin-layer reinforcing material.

- a tape obtained by impregnating adhesive thin resin with a reinforcing fiber single yarn bundle that has been spread and widened so that the width per 1000 pieces of the thin layer reinforcing material is 1.3 mm or more. Since the strength of the body is also increased, it is possible to provide a reinforcing material having high mechanical properties while being thin, lightweight and flexible. Further, by bonding the thin layer reinforcing material to the reinforced substrate, the thickness of the reinforced substrate is heavy and the weight of the reinforced substrate is not greatly changed. Characteristics can be improved.
- the adhesive resin of the thin-layer reinforcing material is a hot melt resin
- the reinforcing material can be bonded to the substrate to be reinforced by thermocompression bonding, thereby greatly simplifying the bonding operation. Can be abbreviated.
- the reinforcing fiber is a carbon fiber

- the thin layer reinforcing material of the first embodiment will be described.
- This thin layer reinforcing material is a thin layer that has a tape-like physical strength in which bundles of reinforcing fiber monofilaments that have been spread and expanded so that the width per 1000 fibers is 1.3 mm or more are impregnated with adhesive grease. It is a reinforcing material.
- the mechanical characteristics of the reinforced substrate can be improved.
- the mechanical properties here refer to the tensile strength and tear strength.
- the reinforced substrate to which the thin-layer reinforcing material of Embodiment 1 is attached is light, thin, and has a flexible property.
- a typical example is a sail of a sailing ship. Raised It is done.
- Other examples of the substrate to be reinforced include a parachute, a tent, a balloon, a membrane material for construction, a casing sheet for a portable electric information device, a bag sheet, and a thin tubular pole. .
- the properties of the substrate to be reinforced include lightness (weight per unit area), thinness (thickness), and flexibility (flexural rigidity per unit width). Are preferably 0.2 gZcm 2 or less, 2 mm or less, and 1.3 Ncm 2 Zcm (N: -Euton) or less, respectively.
- the thin layer reinforcing material of the present invention (hereinafter simply referred to as “reinforcing material” or “reinforcing tape”) will be described.
- the reinforcing tape of the present invention is obtained by impregnating an adhesive resin with a bundle of reinforcing fiber single yarns that have been spread and spread in advance so that the width per 1000 fibers is 1.3 mm or more.
- the thickness of the reinforcing tape can be reduced while maintaining the reinforcing effect, and the degree of weight increase can be reduced.
- a typical example of the reinforcing fiber that spreads and widens is carbon fiber. Since carbon fiber has a high specific modulus and specific strength, it is particularly excellent in that the mechanical properties of the reinforcing tape can be improved efficiently.
- Other examples of the reinforcing fiber include fibers having high mechanical properties such as glass fiber, para-type polyamide fiber, wholly aromatic polyester fiber, ultrahigh molecular weight polyethylene fiber, and poly'benzoxazole fiber.
- ultrahigh molecular weight polyethylene fibers are suitable for reinforcing the base material for sails in terms of lightness, weather resistance, folding resistance, and the like.
- a substantially untwisted reinforcing fiber bundle is run in a relaxed state, and a rectified air flow is substantially orthogonal to the suspended reinforcing fiber bundle. It is preferable to spread and spread the fiber by spraying. If the size of the suspended sag is increased or the flow velocity of the air to be blown is increased, the width to be widened increases. If the flow velocity of the air to be blown is increased, the width to be widened further increases. However, if the width is too wide, the uniformity of fiber distribution in the width direction will decrease, so care must be taken.

- the reinforcing tape 10 since the reinforcing tape 10 only needs to be bonded in the direction in which the mechanical characteristics of the substrate 20 to be reinforced are desired to be strengthened, there is also an effect that the degree of freedom in the direction in which the reinforcement is desired can be increased. For example, as shown in FIG. 7 (a), a uniaxially oriented reinforcing tape 10 may be applied in parallel to one direction, and as shown in FIG.
- the tape 10 may be affixed to the entire substrate to be reinforced 20 as shown in FIG. 7 (c). , It may be attached to only a part. Also, as shown in Fig. 7 (a) and (b), it is only necessary to paste the reinforcing tapes 10 so that they are parallel to each other. Good.
- the above-described uniaxially oriented reinforcement tape 10 has a problem that it takes time to bond. is there. In that case, a bundle of reinforcing fiber single yarns that have been widened and spread is pre-arranged on a multi-axis to produce a tape-like body impregnated with resin 11, and the multi-axis reinforcing tape is applied to the substrate to be reinforced. It is also possible to match. In this way, it is possible to efficiently and uniformly perform biaxial reinforcement, surface reinforcement, or intended reinforcement simply by joining the multiaxial reinforcement tape to the reinforced substrate as it is. .
- a typical example of the multi-axial arrangement of the reinforcing fiber single yarn bundle described above is: 2 axes at 0 degrees Z90 degrees, 3 axes at 0 degrees Z + 60 degrees Z-60 degrees, (0 degrees Z + 45 degrees Z-45 A force that includes four axes (degrees Z90 degrees) is not particularly limited.
- the thin-layer reinforcing material according to the first embodiment is obtained by bonding a bundle of reinforcing fiber single yarns that are spread and widened so that the width per 1000 pieces is 1.3 mm or more. Since the strength of the tape is impregnated with the synthetic resin, it is possible to give the reinforced substrate high mechanical properties without significantly changing the properties such as thickness, weight or flexibility of the reinforced substrate. Can do.
- the thin layer reinforcing material of the present invention is formed by adhering the release tape 13 to at least one surface, when the thin layer reinforcing material 10 is stored, the reinforcing material 10 Since it can be stored in a wound state, it can be stored easily, and when the reinforcing material 10 is bonded to the reinforced substrate, the reinforcing material 10 can be smoothly pulled out and bonded. The working efficiency of the bonding can be increased.
