  • Patent number: 11203178
    Abstract: A reinforced substrate is used for molding a composite material. The reinforced substrate includes a first region and a second region. The first region includes reinforcing fibers extending in a fiber direction that is aligned in a single direction. The second region includes the reinforcing fibers aligned in the same direction as the fiber direction and being thinner than the first region. The first region and the second region are lined up in alternating fashion in a plane along a direction intersecting the fiber direction.

  • Patent number: 11173687
    Abstract: A reinforced substrate is provided for use in molding a composite material. The reinforced substrate has a reinforcing layer having reinforcing fibers extending in a fiber direction that is aligned in a single direction and auxiliary fibers laminated on only one surface of the reinforcing layer so as to extend in only one direction that intersects with the fiber direction. The auxiliary fibers are joined to the reinforcing fibers to hold the reinforcing layer. The auxiliary fibers have a higher tensile elongation at break than do the reinforcing fibers. The reinforcing layer is arranged with fiber bundles of large tows being aligned in an unopened state. The large tows have a higher fiber count of the reinforcing fibers than does a regular tow.

  • Patent number: 10836123
    Abstract: A method of manufacturing a composite material 400 provided with a reinforcement 510 and a resin 600 infused into the reinforcement, includes: an applying process of applying an adhesive 520 to the sheet-shaped reinforcement having first and second regions 501 and 502 such that a content density of the adhesive of the second region is lower than that of the first region; a preforming process of forming a preform 500 by preforming the reinforcement; and a process of molding a composite material 400 by infusing the resin 600 into the preform. The resin injected into the cavity easily flows in a portion of the cavity 350 where the second region of the reinforcement is placed, compared to a portion of the cavity where the first region of the reinforcement is placed.

  • Patent number: 10792839
    Abstract: According to a manufacturing method and device for manufacturing a composite material having reinforced base materials with a resin impregnated in the reinforced base materials. An unactivated powdered adhesive is applied to at least one surface of a plurality of carbon fiber sheets. The carbon fiber sheets are laminated to form a laminate. At least a portion of the unactivated powdered adhesive that is applied between layers of the laminate is removed using an airflow that flows from one exterior surface of the laminate to an opposite exterior surface of the laminate to form a preform having a first region in which the activated adhesive is impregnated in the laminate, and a second region in which a content density of the activated adhesive is less than that in the first region.

  • Patent number: 10717241
    Abstract: To provide a manufacturing method for a composite material, a manufacturing apparatus for a composite material, a preform, and a composite material, capable of molding a high quality composite material having a little constraint in the shape by improving moldability while suppressing a deviation of the arrangement of the reinforced fiber during preforming. A manufacturing method for a composite material 400 provided with a reinforcement 510 and resin 600 infused into the reinforcement, includes: an apply process (step S12) for applying an adhesive to the sheet-shaped reinforcement having first and second regions 511 and 512 such that a content density of the adhesive 520 of the second region is lower than that of the first region; and a preforming process (step S17) for preforming the reinforcement in a three-dimensional shape to form a preform such that the second region has a curvature larger than that of the first region.

  • Patent number: 10673655
    Abstract: In performing SVD-MIMO transmission, a set-up procedure is simplified while assuring a satisfactory decoding capability with a reduced number of antennas. A transmitter estimates channel information based on reference signals sent from a receiver, determines a transmit antenna weighting coefficient matrix based on the channel information, calculates a weight to be assigned to each of components of a multiplexed signal, and sends, to the receiver, training signals for respective signal components, the training signals being weighted by the calculated weights. On the other hand, the receiver determines a receive antenna weighting coefficient matrix based on the received training signals.

  • Patent number: 10440749
    Abstract: Random access operation is performed under a communication environment in which a plurality of communication modes having different transmission rate coexist with small overhead. A high-grade communication station spoofs information of a packet length and a rate in a decoding portion so that a value of (packet length)/(rate) corresponds to a duration where the communication is hoped to be stopped. The other station receiving the spoofed information receives the rest of the packet with the designated rate during the interval designated by the value of (packet length)/(rate). In this case, the packet length and the rate are not those of actually transmitted packet so that this packet is discarded.
