Description
【発明の詳細な説明】 本発明は、軽量化に寄与する補強材に関する。[Detailed description of the invention] The present invention relates to a reinforcing material that contributes to weight reduction.
例えば自動車において、省資源、省エネルギの
ため軽量化が進められている。材料の板厚を下
げ、あるいは構造部材を減らして軽量化を進める
と、強度が落ち、自動車のドアを例にとると、諸
部位の強度の低下、外板面の剛性なかんずく張り
剛性の不足、はたまた操作感不良等の問題があら
われる。 For example, automobiles are being made lighter to save resources and energy. If we reduce the thickness of the material or reduce the number of structural members to reduce the weight, the strength will decrease, and if we take a car door as an example, the strength of various parts will decrease, the rigidity of the outer panel surface will be insufficient, especially the tension rigidity, In addition, problems such as poor operational feel may occur.
このために別の観点からの補強が必要になる。
重い金属板による補強は軽量化に逆行するもので
あるから軽い樹脂板によりドア外板の全面あるい
は局部を強化するものが提案されたりしている。 This requires reinforcement from another perspective.
Since reinforcing with heavy metal plates runs counter to weight reduction, some proposals have been made to strengthen the entire or local part of the outer door panel with light resin plates.
しかし、従来提案されている樹脂板による補強
は、単に薄い樹脂板をドア外板内面に貼着するだ
けであるため、厚さが無いので補強効果が悪く、
肉厚を厚くすれば重量増を招き、厚みを出すため
に樹脂板とドア外板内面との間に充填材を入れた
ものでは、形状に対する追従性が悪かつたり、硬
質発泡材の場合割れてガサガサ音を発したり、構
造が複雑で実用性の無いものであつた。 However, the conventionally proposed reinforcement using resin plates simply involves attaching a thin resin plate to the inner surface of the door outer panel, so the reinforcing effect is poor due to the lack of thickness.
Increasing the wall thickness will increase the weight, and if a filler is inserted between the resin plate and the inner surface of the door outer panel to increase the thickness, it will not be able to follow the shape, and if it is made of hard foam, it will crack. They made a rustling sound and had a complicated structure, making them impractical.
本発明は上記問題点に着目してなされたもの
で、使用前は未硬化で可撓性があるので補強すべ
き部位の形状への追従性が良く、ビード状膨出部

て対象部位を補強し、しかも、割れ防止のために
繊維強化された硬質発泡材の使用により剛性が高
まり僅少の材料で効果的に補強する補強材を提供
するものである。 The present invention has been made in view of the above-mentioned problems, and since it is uncured and flexible before use, it has good ability to follow the shape of the part to be reinforced, and a bead-shaped bulge is formed to allow installation. After that, it hardens and reinforces the target area with sufficient thickness. Furthermore, by using a hard foam material reinforced with fibers to prevent cracking, the stiffness increases and provides a reinforcing material that can be effectively reinforced with a small amount of material. It is something to do.
以下、図示実施例に基づき本発明を説明する。
なお、同一部位には同一符号を付する。 The present invention will be explained below based on illustrated embodiments.
Note that the same parts are given the same reference numerals.

いる。 FIGS. 1 to 3 show the first reinforcing material according to the present invention.
An example is shown, and in the state before use shown in FIGS. 1 and 2, the reinforcing material 1 is made up of a bead forming material 3 having a width narrower than the reinforcing resin layer under the reinforcing resin layer 2. The lower surface of the hem 21 of the reinforcing resin layer 2, which extends wider than the width of the forming member 3, forms a mounting surface 22.

貼着できるようにする。 As the reinforcing resin layer 2, thermosetting resins, particularly epoxy resins, are suitable, but melamine resins, phenol resins, urea resins, etc. may also be used. These resins may be cured by heating, or may be cured at room temperature, and may also be thermoflexible resins that can maintain sufficient strength at the operating temperature. Then, the reinforcing resin layer 2
is prepared in an uncured and flexible prepreg state before use, and the mounting surface 22 is made sticky when used on an vertical surface, etc., as shown in FIG. Alternatively, it can be attached by providing adhesive strength with an adhesive.

泡性シート等に埋設しておけば良い。 As the bead forming material 3, a foamable sheet such as a foamed polyethylene sheet is used, which is flexible before foaming, and foams to become a rigid foaming material when heated. The foamable sheet may be either a thermoplastic resin or a thermosetting resin, and may also be a foaming material that is foamable at room temperature. In order to prevent the foamed material from cracking after foaming, crack-preventing fibers 31 are embedded to strengthen the inside. The reinforcing fibers may be of low strength, such as glass fiber, hemp, nylon, paper, etc., but carbon fibers and metal wires may also be used. Various organic and inorganic fibers can be used, such as woven fabrics, non-woven fabrics,
Single fibers are buried. These fibers may be buried in a foamable sheet or the like before foaming.

た硬質発泡材である。 As shown in FIG. 2, the reinforcing material 1 is pasted and mounted with its mounting surface 22 in contact with the panel A. At this time,
Since the reinforcing resin layer 2 and the bead forming material 3 have flexibility, they have good followability to the shape of the panel A, and since the bead forming material 3 is a foamed sheet before foaming, the followability is particularly good. , the mounting surface 22 is firmly attached to the panel A. When panel A and reinforcing material 1 are heated from this state, the viscosity of reinforcing resin layer 2 temporarily decreases and it becomes more closely attached to panel A.
On the other hand, the bead forming material 3 foams to have a larger cross section, and the reinforcing resin layer 2 is pushed up, forming a bead-shaped bulge 23 before hardening. As the heating progresses over time, the reinforcing resin layer 2 hardens and follows the shape of the panel A to form a reinforcing material 1 as shown in FIG. 3. Furthermore, the bead forming material 3 inside the bead-shaped swollen portion 23 is a hard foam material reinforced with crack-preventing fibers 31.

実施例と同様である。 FIG. 4 shows a second embodiment of the reinforcing material, and the reinforcing resin layer 2 includes a reinforcing resin layer 24 reinforced with upper glass fibers and a soft resin layer 25 that foams when hardened and hardens with a predetermined elasticity. It is composed of two layers, and
A film 26 made of polyester or the like is attached to the surface. Therefore, the lower surface of the soft resin layer 25 appears on the mounting surface 22. On the other hand, in panel A,
A rust preventive film 5 is applied. The bead forming material 3 is the first
This is similar to the example.
強化樹脂層２４は、補強樹脂層２を繊維で強化

強化手段がとり得る。 The reinforcing resin layer 24 improves the reinforcing effect by reinforcing the reinforcing resin layer 2 with fibers, and may use various organic and inorganic fibers such as carbon fiber, metal wire, hemp, nylon, and paper in addition to glass fiber. It can be strengthened by woven fabric, non-woven fabric, single fiber kneading, embedding, attachment, etc.

ることもできる。 The soft resin layer 25 is provided to prevent sink marks on the surface of the panel A caused by expansion and contraction of the resin, and is effective if it is provided at least on the mounting surface 22. If the elasticity of the soft resin layer 25 is too low, the reinforcing effect of the reinforcing material 1 will be reduced, but since the degree of occurrence of sink marks varies depending on the thickness of the panel A, etc., it is set in advance so that it has a predetermined elasticity. In addition, the soft resin layer 25
can also be used with a hard resin layer that is not reinforced with fibers.
フイルム２６は、補強樹脂層２に粘着性があつ
た場合、取扱時に付着しないようにして取り扱い
易くするもので粉でも同様の目的を達することが
できる。 The film 26 makes it easier to handle by preventing adhesion to the reinforcing resin layer 2 when it becomes sticky, and the same purpose can be achieved using powder.
防錆膜５は、パネルＡが鋼板であつた場合に、
塗料のつき回りが特に界面等で悪くなつて発錆す

付加適用して用いることができる。 When the panel A is a steel plate, the antirust film 5 is
In order to prevent rust from occurring due to poor paint coverage, especially at interfaces, a zinc-treated film, paint film, etc. is applied to the surface of panel A. Each configuration added in the second embodiment can be selectively added to and used in the first embodiment as appropriate.
次に補強材１により効果的に補強された補強パ
ネルについて第５図および第６図により説明す
る。 Next, a reinforcing panel effectively reinforced by the reinforcing material 1 will be explained with reference to FIGS. 5 and 6.

がら、中央部だけに補強材を装着硬化してもあま
り効果は無い。なぜならば、その部位の荷重を分
担すべき基礎が無いからである。 The object shown in Fig. 5 is a car door, and the outer panel 5 is relatively flat, so if the weight is reduced and the thickness of the steel plate is reduced, the rigidity will be insufficient, and the surface tension will be insufficient and the rigidity will become uneven. , the operability of the door tends to be poor. Looking at the panel 5, the upper side 51, the lower side 52, the front side 53, and the rear side 54 are supported by the inner plate and have high rigidity, and the character line 55 also has high rigidity because it has a thick cross section. The center and surrounding areas have low rigidity and require reinforcement. However, attaching and hardening the reinforcing material only to the central portion does not have much effect. This is because there is no foundation to share the load of that part.

強している。 In the embodiment shown in FIG.
The reinforcing material 1 is stretched over the parts and hardened to reinforce the low-rigidity part in the center between them, and furthermore, the reinforcing material 1 is extended to the lower side 52 to reinforce the lower low-rigidity part. Furthermore, the reinforcing material 1 is spread between the front side 53 and the rear side 54 to reinforce the entire upper low-rigidity region.
第６図に示す実施例では、上方のキヤラクタラ
イン５６と下方のビード様のキヤラクタライン５

中間の平坦面５８を補強している。 In the embodiment shown in FIG. 6, there is an upper character line 56 and a lower bead-like character line 5.
A reinforcing material 1 is spread between the reinforcing material 7 and the reinforcing material 1, and the intermediate flat surface 58 is reinforced by being hardened.
補強材１を上記各実施例のように配設すれば、
低剛性部位への荷重は補強材１を介して高剛性部
位に伝達され支持されるから著しく補強効果は上
がる。 If the reinforcing material 1 is arranged as in each of the above embodiments,
Since the load on the low-rigidity portion is transmitted to and supported by the high-rigidity portion via the reinforcing member 1, the reinforcing effect is significantly improved.
なお、補強材１自体の形態あるいは装着時の配
置は直線状に限らず曲線状でも良く、格子状その
他の適宜なパターンに配設しても良い。 Note that the shape of the reinforcing material 1 itself or its arrangement at the time of attachment is not limited to a straight line, but may be curved, or may be arranged in a grid or other appropriate pattern.

きる。 According to the reinforcing material according to the present invention, since it is flexible before use, it adheres closely to the shape of the object to be reinforced with good followability, so there is no need for shaping. Furthermore, after installation and curing, a bead-shaped bulge with sufficient height and filled with a highly rigid foamed material is formed, exhibiting overall high rigidity, and thus strongly reinforcing the object. Compared to those using flat plates, it has a higher weight-to-weight ratio, contributes to weight reduction, and is lower in cost. Moreover, since the hard foam material is reinforced with fibers to prevent cracking, it will not crack even if it is temporarily deformed significantly, and the rustling noise caused by cracking will not be generated.
For products that are cured or foamed by heat, the furnace used in the painting process of automobile production lines can be used as is. In addition, it can be made into a highly practical reinforcing material by applying anti-rust measures, fiber reinforcement, sink mark measures, etc.
