Description
本発明は、繊維強化樹脂（Ｆｉｂｅｒ Ｒｅｉｎｆｏｒｃｅｄ Ｐｌａｓｔｉｃｓ：以下、ＦＲＰと称することがある）製の自動車用フード（ボンネット）に関し、とくに衝突時などの衝撃力が加わった際に破断せず破片が飛び散らないようにした自動車フードに関する。 The present invention relates to an automobile hood (bonnet) made of fiber reinforced resin (hereinafter also referred to as FRP), and particularly, when an impact force such as a collision is applied, it does not break and fragments do not scatter. It relates to the car hood.
近年、燃費や運動性能の向上のための軽量化のため、自動車の外板部材のＦＲＰ化が進んでいる。特にフードは面積も大きく車体上部にあるため軽量化効果が比較的大きく、各社開発を進めている。 2. Description of the Related Art In recent years, the use of FRP for automobile outer plate members has been advanced in order to reduce the weight for improving fuel consumption and exercise performance. In particular, the hood has a large area and is located at the top of the vehicle body, so the effect of weight reduction is relatively large.
自動車が正面衝突した際、フードを折り曲げるように設計される。折り曲がらず突っ張ったままでは、ヒンジ部分に過大な力が加わって破壊することにより、フードがフロントガラスを突き破り乗員に傷害を与えるおそれがある。 Designed to bend the hood when the car collides head-on. If the hood is stretched without being bent, the hood may break through the windshield and cause injury to the occupant due to an excessive force applied to the hinge portion for destruction.
フードを折り曲げるには、折り曲げようとする場所に破壊起点を設ける設計が一般に行われている。たとえば特許文献１では、積層材からなるＦＲＰ製フードの一部の層において、強化繊維に切断線を入れることにより、折り曲げる破壊起点としている。 In order to bend the hood, a design in which a breakage starting point is provided at a place to be folded is generally performed. For example, in Patent Document 1, in some layers of an FRP hood made of a laminated material, a break starting point is formed by putting a cutting line in the reinforcing fiber.
しかしながら、ＦＲＰは塑性変形しないか、塑性変形しづらい材料であり、この破壊起点で破断してしまうおそれがある。破断した場合、破片の一部が飛び散り、フロントガラスを突き破り乗員に傷害を与えるなどといった被害を拡大させるおそれがある。これを防ぐため、特許文献１では、一部の層を破断防止層とすることが提案されており、具体的にはアラミド繊維を含む層を破断防止層とする実施形態が記載されている。 However, FRP is a material that does not plastically deform or is difficult to be plastically deformed, and there is a possibility that it will break at this fracture starting point. If it breaks, some of the fragments may scatter and break through the windshield and injure the passenger. In order to prevent this, Patent Document 1 proposes that a part of the layers is a rupture prevention layer, and specifically describes an embodiment in which a layer containing an aramid fiber is a rupture prevention layer.
しかし、破断防止に適用可能なアラミド繊維やその他の有機繊維は、ＦＲＰの母材となる樹脂との接着性が悪いものが多く、また吸水により膨潤するものが多い。そのため破断防止層として広い面積に積層すると、雨水などにより吸水膨潤した結果、母材樹脂と剥離し、フードが二枚に分離してしまう。長期間の使用に耐えられない。 However, aramid fibers and other organic fibers that can be used for preventing breakage are often poor in adhesion to the resin that is the base material of FRP, and often swell due to water absorption. Therefore, when it is laminated on a wide area as a breakage preventing layer, it absorbs and swells due to rain water or the like, resulting in separation from the base material resin and separation of the hood into two pieces. It cannot withstand long-term use.
さらに、アラミド繊維やその他の有機繊維は弾性率がＦＲＰの強化繊維としてよく用いられるガラス繊維や炭素繊維より低いため、破断防止層はフードの剛性への寄与は少なく、広い面積に積層すると重量的に不利である。 Furthermore, since aramid fibers and other organic fibers have a lower elastic modulus than glass fibers and carbon fibers, which are often used as FRP reinforcing fibers, the anti-breaking layer contributes little to the rigidity of the hood, and is heavy when laminated over a large area Disadvantageous.
そこで本発明の課題は、上記のような従来のＦＲＰ製フードにおける問題点に着目し、衝突事故時等に対する要求性能、とくに軽量性を維持したままフードを折り曲げる形に変形したあとも、破断せず破片も飛散しないＦＲＰ製フードを提供することにある。 Therefore, the object of the present invention is to focus on the problems in the conventional FRP hood as described above, and to break even after the hood is bent while maintaining the required performance at the time of a collision accident, especially the lightness. An object of the present invention is to provide an FRP hood that does not scatter fragments.
本発明は、前記した課題を解決するために以下のような構成からなるものである。

本発明によれば、軽量性を維持したまま、衝突時などの衝撃力が加わった際に破断せず破片も飛び散らない自動車フードを提供することができる。 According to the present invention, it is possible to provide an automobile hood that is not broken and does not scatter fragments when an impact force such as a collision is applied while maintaining lightness.
以下、本発明について図面を用いて説明する。 The present invention will be described below with reference to the drawings.
図１は、本発明の自動車用フードを、エンジン側から見た概略斜視図である。自動車用フード１はＦＲＰ（繊維強化プラスチック）製面状部材を有する。ヒンジ取付位置とストライカ取付位置との間を結ぶように、連続繊維糸条２が配置されている。この連続繊維糸条２は、ＦＲＰ用強化繊維よりも破断伸度の大きい連続繊維糸条からなる。この連続繊維糸条２により、自動車衝突時等で仮にＦＲＰ部分が破断しても破片が飛散することを防止することができる。 FIG. 1 is a schematic perspective view of the automobile hood of the present invention as viewed from the engine side. The automobile hood 1 has a surface member made of FRP (fiber reinforced plastic). The continuous fiber yarn 2 is arranged so as to connect the hinge attachment position and the striker attachment position. The continuous fiber yarn 2 is a continuous fiber yarn having a higher elongation at break than the reinforcing fiber for FRP. The continuous fiber yarn 2 can prevent fragments from being scattered even if the FRP portion is ruptured during an automobile collision or the like.
本発明の自動車用フード１の組立構造の概略斜視図を図２に示す。図２に示すように、自動車用フード１はインナーパネル３とアウターパネル４とを組み合わせた構成を含むことが好ましい。この構成により必要な剛性を確保したうえで軽量とすることができる。 A schematic perspective view of the assembly structure of the automobile hood 1 of the present invention is shown in FIG. As shown in FIG. 2, the automobile hood 1 preferably includes a configuration in which an inner panel 3 and an outer panel 4 are combined. With this configuration, the required rigidity can be secured and the weight can be reduced.
ＦＲＰ用強化繊維として、ガラス繊維、炭素繊維、アラミド繊維、ボロン繊維などが使用できる。なかでも炭素繊維は軽量でかつ弾性率や強度も高いために、本発明の自動車用フードの材料としてより好ましい。ＦＲＰ用樹脂は熱可塑性樹脂、熱硬化性樹脂どちらでも使用することができる。熱可塑性樹脂であればナイロン樹脂、熱硬化性樹脂であればエポキシ樹脂が、強度、耐熱性などの点から好適である。成形法はプリプレグのオートクレーブ成形やプレス成型、スタンパブル基材のプレス成型、ＲＴＭやハンドレイアップ法などどのような成形法も適用可能である。 As the reinforcing fiber for FRP, glass fiber, carbon fiber, aramid fiber, boron fiber or the like can be used. Among these, carbon fiber is more preferable as a material for the automobile hood of the present invention because it is lightweight and has high elastic modulus and strength. As the FRP resin, either a thermoplastic resin or a thermosetting resin can be used. Nylon resin is preferable for thermoplastic resin, and epoxy resin is preferable for thermosetting resin from the viewpoint of strength and heat resistance. As the molding method, any molding method such as prepreg autoclave molding, press molding, press molding of a stampable base material, RTM or hand lay-up method can be applied.
連続繊維糸条２として、アラミド繊維（破断伸度２．４−４．４％）、ポリエステル繊維（同７−４０％）、ナイロン繊維（同１５−４５％）、ＰＢＯ繊維（２．５−３．５％）、ポリケトン繊維（同５−７％）、ポリエチレン繊維（同３−５％）、ポリエーテルイミド繊維（同７０％）が、炭素繊維（同０．５−２．２％）よりも破断伸度が大きく好ましい。連続繊維糸条２は破断を防ぐためのものであるので、一方向に引きそろえられて繊維束となっていることが好ましい。連続繊維糸条２として上記に挙げた繊維のうちの１つを一方向に引きそろえた繊維束、もしくは複数種類の繊維を混合し一方向に引きそろえた繊維束のいずれであっても構わない。 As the continuous fiber yarn 2, aramid fiber (breaking elongation 2.4-4.4%), polyester fiber (7-40%), nylon fiber (15-45%), PBO fiber (2.5- 3.5%), polyketone fiber (5-7%), polyethylene fiber (3-5%), polyetherimide fiber (70%), carbon fiber (0.5-2.2%) The elongation at break is large and preferable. Since the continuous fiber yarn 2 is for preventing breakage, it is preferable that the continuous fiber yarns 2 are aligned in one direction to form a fiber bundle. The continuous fiber yarn 2 may be either a fiber bundle in which one of the fibers listed above is aligned in one direction or a fiber bundle in which a plurality of types of fibers are mixed and aligned in one direction. .
連続繊維糸条２をインナーパネル３やアウターパネル４の外表面や内表面に貼付することが、本発明の好ましい一形態である。貼付方法としては、粘着テープ、接着剤等で貼付することができる。また、インナーパネル３とアウターパネル４とを接合する際にその接合面に配置することにより、接合部内に埋め込むことも好ましい一形態である。また、インナーパネル３やアウターパネル４が積層構造の場合、いずれかの層間に連続繊維糸条２を配置したあと成形し内部に埋め込むのも好ましい一形態である。また、インナーパネル３やアウターパネル４を射出成形やＳＭＣ成形で作成する際に、型内にあらかじめ連続繊維糸条２を配置した状態で、ＦＲＰ材料を射出もしくは加圧流動させて成形し内部に埋め込むのも好ましい一形態である。 It is a preferred embodiment of the present invention that the continuous fiber yarn 2 is stuck on the outer surface or inner surface of the inner panel 3 or the outer panel 4. As an affixing method, it can be affixed with an adhesive tape, an adhesive or the like. In addition, when the inner panel 3 and the outer panel 4 are joined, the inner panel 3 and the outer panel 4 are also disposed on the joining surfaces, and are preferably embedded in the joining portion. Further, when the inner panel 3 and the outer panel 4 have a laminated structure, it is also a preferred form that the continuous fiber yarn 2 is disposed between any layers and then molded and embedded in the inside. Further, when the inner panel 3 and the outer panel 4 are formed by injection molding or SMC molding, the FRP material is injected or pressure-flowed and molded in a state where the continuous fiber yarns 2 are arranged in advance in the mold. Embedding is also a preferred form.
連続繊維糸条２は自動車用フード１の周縁部に沿って配置されることが好ましい。ヒンジ位置とストライカ位置を最短距離で直線的に結ぶなら、連続繊維糸条２よりも車体側面側部分の面積が大きくなり、自動車衝突時等にこの部分の一部が破断分離して飛散する可能性がある。その場合比較的大きな破片が飛散するので乗員その他に障害を与える可能性がある。そのため連続繊維糸条２よりも車体側面側の面積を小さくするために周縁部に沿って配置されることが好ましい。 The continuous fiber yarn 2 is preferably disposed along the peripheral edge of the automobile hood 1. If the hinge position and the striker position are connected linearly at the shortest distance, the area of the side of the vehicle body will be larger than the continuous fiber yarn 2, and part of this part can be broken and scattered in the event of a car crash, etc. There is sex. In that case, relatively large fragments may scatter, which may cause damage to passengers and others. Therefore, in order to make the area on the side surface of the vehicle body smaller than the continuous fiber yarn 2, it is preferably arranged along the peripheral edge.
ヒンジ取付位置にヒンジ補強材５、ストライカ取付位置にストライカ補強材６が配置され、それぞれの補強材は金属製であることが好ましい。自動車衝突時にはヒンジ取付位置、ストライカ取付位置に荷重が集中するためである。連続繊維糸条２はこれらの補強材に係止されていることが好ましい。係止することにより自動車衝突時等に連続繊維糸条２が端部まで引き抜かれてしまうことを避けることができる。 It is preferable that the hinge reinforcement member 5 is disposed at the hinge attachment position and the striker reinforcement member 6 is disposed at the striker attachment position, and each reinforcement member is made of metal. This is because the load concentrates on the hinge mounting position and the striker mounting position during a car crash. The continuous fiber yarn 2 is preferably locked to these reinforcing materials. By locking, it is possible to prevent the continuous fiber yarn 2 from being pulled out to the end in the event of an automobile collision or the like.

Example 1
An automobile hood having the shape shown in FIG. 1 was molded. Three layers of prepregs (FK6241E-05K manufactured by Toray Industries, Inc.) made of carbon fiber with a modulus of elasticity of 235 GPa, tensile strength of 5 GPa, and elongation at break of 2.1% and impregnated with epoxy resin are laminated, and inner panels and outer layers are formed by autoclave molding. Molded as a panel. An aramid fiber (Kevlar 119 manufactured by Toray DuPont Co., Ltd.) having a breaking elongation of 4.4% was attached to the upper surface (outer panel side) surface of the inner panel with an adhesive tape (540S manufactured by Teraoka Seisakusho). Moreover, the edge part of the continuous fiber yarn was passed through the hole provided in the steel hinge reinforcement material and striker reinforcement material, and was locked. The inner panel and the outer panel, the inner panel and the hinge reinforcing material, and the striker reinforcing material were bonded and assembled with a urethane-based adhesive (Eitec Mighty Grip 5000).
