Definitions
- the present invention relates to a fiber reinforced resin structure, and in particular, a fiber reinforced resin structure having a hole into which a connector to another member is inserted, for example, a vehicle part, particularly a frame structure for a seat back of a vehicle seat.
- the present invention relates to a fiber reinforced resin structure suitable for application to the above.
- fiber reinforced resin can exhibit extremely high strength and rigidity, it causes brittle fracture to impact loads, resulting in local fracture, and in areas where such fracture is undesirable.
- the impact energy can be absorbed by the additional mechanism, for example, the member that connects the fiber reinforced resin structure to the other member is deformed or broken first at a load lower than the load causing the brittle fracture.
- the fiber reinforced resin structure itself was prevented from being broken. That is, in addition to the fiber reinforced resin structure, a mechanism for safely breaking or absorbing impact energy has been provided.

- Patent Document 3 the fastening part of the automotive part formed in the laminate of the fiber reinforced resin sheet material is configured to bite into the interlayer of the sheet material on which the fastener is laminated.
- a structure is disclosed in which delamination occurs to absorb impact loads.
- Patent Document 3 since the structure disclosed in Patent Document 3 is premised on deformation and breakage in the delamination direction, which is usually most likely to be weakest in the fiber reinforced resin structure, the fiber reinforced resin structure is originally targeted. It may be difficult to exert high mechanical properties. That is, it has a structure that sacrifices high mechanical properties that are originally targeted.
- the object of the present invention is to focus on the problems in the prior art as described above, and without causing an increase in the number of parts and the assembly process, while easily exhibiting high mechanical properties that are originally targeted, It is an object of the present invention to provide a fiber reinforced resin structure capable of absorbing a load applied from the outside such as impact energy very efficiently only by necessary deformation and displacement of a local part.
- a fiber reinforced resin structure according to the present invention is a fiber reinforced resin structure having a hole into which a connector to another member is inserted, and a load from the connector acts on the fiber reinforced resin structure.
- a bearing strength expressed as a stress when the displacement of the inner surface portion of the hole starts to increase even if the load from the coupling member acting on the inner surface portion of the hole does not increase at the inner surface portion of the hole is the structure. It consists of what is characterized by being smaller than the breaking strength of the fiber reinforced resin which comprises the site
- the fiber reinforced resin part forming the inner surface of the hole is gradually broken locally from the inner surface of the hole toward the part away from the inner surface by a load acting from the coupling tool.
- the holes are enlarged as the successive destruction progresses. With this deformation, the energy of the load acting on the inner surface of the hole is consumed for the deformation of the hole, and the energy due to the external load is appropriately absorbed. Therefore, externally applied loads such as impact energy can be efficiently absorbed by only local displacement and deformation around the hole without local breakage of the fiber reinforced resin structure.
- the hole into which the connector is inserted can take the form of a hole that does not penetrate in the thickness direction of the fiber reinforced resin structure. It is also possible to adopt.

It is possible to appropriately increase the breaking strength of the resin and easily set the bearing strength at the inner surface portion of the hole to a target strength.
- the starting point of the start of displacement of the inner surface portion of the hole is applied to the inner surface portion of the hole to which the load from the connector of the structure acts. It is also possible to adopt a structure in which a trigger is provided. By providing the trigger in an appropriate part in an appropriate form, it is possible to reliably start the displacement of the inner surface part of the desired hole, and it is possible to continue the desired displacement even after the start.
- Such a trigger can be formed from a notch formed in the inner surface portion of the hole.
- the trigger need only be a starting point for the displacement of the inner surface portion of the hole, so that it does not need a large shape. If the shape of the trigger becomes too large, the strength of the fiber reinforced resin at that portion may be weakened.

- the arranged form is preferred.
- Such a continuous reinforcing fiber can be easily arranged as long as it is a peripheral portion of a structure having holes.
- the continuous reinforcing fiber as described above a type of reinforcing fiber different from the reinforcing fiber used for the fiber reinforced resin constituting the peripheral portion of the hole can be used. By using different types of reinforcing fibers, the relative strength of the part can be improved efficiently.
- the type of the reinforcing fiber of the fiber reinforced resin constituting the structure in the present invention is not particularly limited.
- the mechanical properties of the fiber reinforced resin are kept high, and the bearing strength in the present invention is accurately set to a desired value.

- the bearing strength S is a fiber as a material constituting the inner surface portion of the hole 2a and its peripheral portion. It is set to be smaller than the breaking strength of the reinforced resin.
- the bearing strength S of the inner surface portion of the hole 2a is smaller than the breaking strength of the fiber reinforced resin, when an impact load or the like is applied, the fiber reinforced resin as a constituent material is torn around the hole 2a to cause the breaking.
- sequential destruction occurs locally around the hole 2 a in the inner surface direction (surface pressure direction) of the hole 2 a to which a load from the bolt 6 as a coupling tool is applied (sequential destruction part). 5)
- the hole 2a is successively enlarged and deformed into a long hole. In the process of local sequential destruction, the energy of the applied load is consumed and absorbed. Therefore, impact energy is efficiently absorbed by local deformation around the hole 2a without causing breakage of the fiber reinforced resin itself constituting the frame structure 1 for seat back.
- the fiber reinforced resin structure can be provided with high mechanical properties that are originally targeted. In other words, while exerting high mechanical properties desirable for fiber reinforced resin structures, external loads such as impact energy are applied to the fiber reinforced resin structure itself (particularly by designing the fiber reinforced resin structure itself to a specific structure).

- a load is applied using an Instron testing machine
- the pin 14 is displaced in the direction of the arrow, and the bearing strength of the inner surface portion (lower surface side portion) of the hole 13 is obtained.
- the inner surface portion (lower surface portion) of the hole 13 is locally displaced (that is, the hole 13 is deformed into a long hole shape),
- the displacement is measured as the displacement of the pin 14, and for example, a load-displacement characteristic diagram as shown in FIG. 6 is obtained.

図1、図2は、本発明の一実施態様を示しており、とくに、本発明に係る繊維強化樹脂構造体を車両用シートのシートバック用フレーム構造体として構成した場合について示している。図1、図2において、1は、本発明に係る繊維強化樹脂構造体の一例としての車両用シートのシートバック用フレーム構造体を示している。シートバック用フレーム構造体1は、強化繊維として炭素繊維を用いた繊維強化樹脂構造体の一体成形体に構成されている。シートバック用フレーム構造体1の下部の両側には、それぞれ、他部材、例えば、シートフレーム3の一部を構成する回動調整部材4へ連結するための連結具(例えば、ボルト)が挿入される、略水平方向に配列された2つの孔2a、2bが設けられている。本例では、図に示すように、例えば、車両後突時にシートバック用フレーム構造体1の上部に車両後方に向けて加わる衝撃荷重(F)を例にとってみると、孔2bは荷重(F)が加わった際の回動支点として機能し、孔2aの内面に、連結具としてのボルトからの荷重が加わることになる。すなわち、荷重(F)によって腕の長さをd1とするモーメントが孔2b周りに発生し、それに対抗するように、腕の長さを孔2a、2bの中心間距離d2とするモーメントが反対方向に発現し、それに伴って、孔2aの内面には、下向きの荷重S1が加わることになる。
