  • Publication number: 20230144658
    Abstract: A monitoring system according to one aspect of the present disclosure includes: a sensor to measure physical quantities at one or a plurality of measurement points of a structural body; processing circuitry configured to acquire measured values from the measurer; a memory to store the measured values acquired from the measurer; and a data storage that, when one or some of the measured values stored in the memory satisfy a predetermined trigger condition, and as a result, it is determined that the structural body has received impact, records a group of data of the measured values which are within a certain time range and include the measured value based on which it is determined that the trigger condition is satisfied.

  • Patent number: 10518484
    Abstract: A bonded structure includes a first fiber part (12) and a second fiber part (14) arranged between a first member (10) and a second member (20). The first fiber part (12) and the second fiber part (14) are bonded so as to connect the first member (10) and the second member (20) to each other. The first fiber part (12) and the second fiber part (14) are arranged so that the fibers constituting the first fiber part (12) and the second fiber part (14) are oriented in a direction from the first member (10) toward the second member (20).

  • Patent number: 10345515
    Abstract: The purpose of the present invention is to provide a bonded structure, a method for manufacturing the same, and a bonding state detection method which are capable of determining whether or not members are bonded together appropriately. A bonded structure 10 includes a laminated sheet 12A, a laminated sheet 12B, an adhesive 14 that bonds the laminated sheet 12A and the laminated sheet 12B together, and a distributed optical fiber 16 sandwiched between the laminated sheet 12A and the laminated sheet 12B. The cross-sectional shape of the distributed optical fiber 16 is deformed in accordance with the bonding state.

  • Patent number: 10145786
    Abstract: A bonded structure includes a first member, a second member, an adhesive that bonds the first member and the second member together, and an optical fiber sandwiched between the first member and the second member. When pressure is applied to the optical fiber only from a predetermined direction, the sectional shape of the optical fiber changes to an elliptical shape, so that birefringence occurs, whereby the shape of the light spectrum changes so as to have multiple peaks. The optical fiber is used as a sensor for detecting the bonding condition between the first member and the second member based on the birefringence.

  • Publication number: 20160069793
    Abstract: A bonded structure (10) includes a laminate (12A), a laminate (12B), an adhesive (14) that bonds together the laminate (12A) and the laminate (12B), and an optical fiber (16) sandwiched between the laminate (12A) and the laminate (12B). When a pressure is applied to the optical fiber (16) only from a predetermined direction, the sectional shape of the optical fiber (16) changes to an elliptical shape, so that birefringence occurs, whereby the shape of the light spectrum changes so as to have multiple (e.g., two) peaks. The optical fiber (16) is used as a sensor for detecting the bonding condition between the laminate (12A) and the laminate (12B) based on this birefringence. Thus, with the bonded structure 10, it is possible to determine whether members are bonded together appropriately.

  • Patent number: 8746991
    Abstract: A method of repairing an embedded optical fiber of a composite material structure including an embedded optical fiber embedded in a composite material, includes removing a portion of the composite material including a damaged portion of the embedded optical fiber to form an opening portion; polishing an end surface of the embedded optical fiber exposed in the opening portion and an end surface of the composite material exposed in the opening portion; and performing position adjustment such that a core of the polished embedded optical fiber and a core of a replacement optical fiber are aligned with each other, butting the end surface of the embedded optical fiber and an end surface of the replacement optical fiber with each other, and connecting the end surface of the embedded optical fiber and the end surface of the replacement optical fiber together.
