【発明の詳細な説明】 本発明は、ＦＲＰの成形方法に関するものである。[Detailed description of the invention] The present invention relates to a method for molding FRP.
樹脂を繊維で強化してなるＦＲＰ（繊維強化プラスチッ
ク：Ｆｉｂｅｒ ＲｅｉｎｍｃｅｄＰｌａｓｔｉｃｓ）
は、軽量かつ高強度、高弾性であるという優れた特長を
有しているため、いろいろな産業分野において広く用い
られる。FRP (Fiber Reinforced Plastics) made by reinforcing resin with fibers
has the excellent features of being lightweight, high strength, and high elasticity, so it is widely used in various industrial fields.
このようなＦＲＰは、従来、たとえばプリプレグ法と呼
ばれる方法や樹脂含浸法と呼ばれる方法によって作られ
ている。Such FRP has conventionally been produced, for example, by a method called a prepreg method or a method called a resin impregnation method.
すなわち、プリプレグ法は、補強用繊維材料に熱硬化性
樹脂を含浸予備硬化させた、いわゆるプリプレグを用い
、このプリプレグをたとえば金型の中に積み重ね、加熱
加圧して成形する方法である。That is, the prepreg method is a method in which so-called prepreg, which is a reinforcing fiber material impregnated with a thermosetting resin and precured, is stacked in, for example, a mold, and molded by heating and pressing.

浸を行うので、成形工程の作業環境が悪いという欠点が
あった。The resin soaking method is a method in which a reinforcing fiber material is cut into a desired shape, impregnated with liquid resin, and immediately molded. However, in the prepreg method described above, it is necessary to prepare prepregs made of various types of thermosetting resins and reinforcing fiber materials in advance so as to be compatible with any type and shape of FRP. There was a drawback. In addition, prepreg is stored in a refrigerated or frozen state to prevent the thermosetting resin from completely curing before molding, but as mentioned above, it is necessary to make many different types of prepreg. Since it is stored with the reinforcing fiber material included, it has the disadvantage of requiring a large storage facility. Furthermore, the resin immersion method has the disadvantage that the reinforcing fiber material is impregnated with liquid resin immediately before molding, resulting in a poor working environment during the molding process.
本発明の目的は、従釆のＦＲＰの成形方法の上記欠点を
解決し、樹脂や補強用繊維材料の組み合わせの自由度が

ＲＰの成形方法を提供するにある。The purpose of the present invention is to solve the above-mentioned drawbacks of conventional FRP molding methods, to have a large degree of freedom in combining resins and reinforcing fiber materials, and to easily mold FRP in various shapes. Furthermore, the working environment in the molding process is good, and the overall cost of FRP can be reduced.
The present invention provides a method for molding RP.

である。The present invention achieves the above object by overlapping a reinforcing fiber material and a thermoplastic resin material or a semi-hardened thermosetting resin material prepared separately from the reinforcing fiber material during molding, and The FRP molding method is characterized in that the reinforcing fiber material is soaked with the resin of the resin material by heating and pressurizing the reinforcing fiber material in the above state, and the resin is further cured.
本発明にいう“半硬イａ氏態の熱硬化性の樹脂材料”と
は、液状のように流動性は有しないが、完全には硬化し
ていないような熱硬化性樹脂であって、かつシート状や
テープ状、棒状のような形態を有するものをいう。In the present invention, the "semi-hard thermosetting resin material in A mode" refers to a thermosetting resin that does not have fluidity like a liquid, but is not completely hardened. It also refers to something that has a sheet-like, tape-like, or rod-like shape.
上記のような半硬イＱ伏態の熱硬化性樹脂は、加熱する

のである。The reinforcing fiber materials used in the present invention are high-strength, high-elastic fibers such as carbon fibers, glass fibers, silicon carbide fibers, poron fibers, organic high-elastic fibers, polyamide fibers, and polyester fibers in the form of sheets or tapes. It looks like it has been processed into a hose shape. Examples include various types of woven and knitted fabrics, blinds, mats, and braids. The thermosetting resin constituting the semi-cured thermosetting resin material includes epoxy resin, unsaturated polyester resin, polyimide resin, and phenol resin.
樹脂材料はまた、ポリアミド系樹脂やアクリルニトリル

することによって流動性を有するようになり、補強用繊
維材料に含浸される。さて、上述したような補強用繊維
材料と樹脂材料を用いてＦＲＰを成形するには、たとえ
ば次のようにして行う。The resin of such a thermoplastic resin material becomes fluid when heated during molding, and is impregnated into the reinforcing fiber material. Now, in order to mold FRP using the above-mentioned reinforcing fiber material and resin material, it is carried out, for example, as follows.
すなわち、板状のＦＲＰを成形するような場合には、シ
ート状の補強用繊維材料とシート状の樹脂材料とを用い
、これらの所要複数枚を金型内に交互に重ね合わせて積
み、加熱加圧して補強用繊維材料に樹脂材料の樹脂を含
浸させ、さらに樹脂を硬化させる。In other words, when molding a plate-shaped FRP, a sheet-shaped reinforcing fiber material and a sheet-shaped resin material are used, and the required number of sheets are stacked alternately in a mold and heated. Pressure is applied to impregnate the reinforcing fiber material with the resin of the resin material, and the resin is further cured.
管状のＦＲＰを成形するような場合には、１枚のシート

樹脂を含浸させ、さらに樹脂を硬化させた後マンドレル
を引き抜く。When molding tubular FRP, one sheet of reinforcing fiber material and one sheet of resin material are overlapped, wrapped around a mandrel with the resin material on the inside, and then After wrapping a heat-shrinkable film on top, it is heated in an oven to impregnate the reinforcing fiber material with the resin of the resin material, and after the resin is further cured, the mandrel is pulled out.
このとき、樹脂材料が補強用繊維材料の外側になるよう
に巻き付けることができるが、特に薄肉の管状ＦＲＰを
成形する場合は、上述したように樹脂材料が内側になる
ように巻き付けるほうが、成形時のポィドが少なくなる

ト状の樹脂材料を重ね合わせて用いてもよいし、それぞ
れの複数枚を交互に重ね合せて用いてもよい。以上説明
したように、本発明のＦＲＰの成形方法は、補強用繊維
材料とこの補強用繊維材料とは別に用意した熱可塑性の
樹脂材料または半硬イひ伏態の熱硬化性の樹脂材料とを
成形時に重ね合わせて成形するので、補強用繊維材料と
樹脂との組み合わせの自由度が大きく、いろいろな種類
や形状のＦＲＰを簡単に成形することができる。At this time, it is possible to wrap the resin material on the outside of the reinforcing fiber material, but especially when molding thin-walled tubular FRP, it is better to wrap it so that the resin material is on the inside as described above. This is preferable because it reduces the number of pods. In addition, when adopting such a molding method,
A sheet-like reinforcing fiber material may be sandwiched with sheet-like resin materials stacked on both sides thereof, or a plurality of sheets of each resin material may be stacked alternately. As explained above, the FRP molding method of the present invention uses a reinforcing fiber material and a thermoplastic resin material or semi-rigid thermosetting resin material prepared separately from the reinforcing fiber material. Since these are overlapped during molding, there is a large degree of freedom in combining the reinforcing fiber material and resin, and various types and shapes of FRP can be easily molded.
また、従来のプリプレグ法のように、補強用繊維材料に
樹脂を含浸した状態のまま冷蔵または冷凍保管する必要
がなく、樹脂材料のみを補強用繊維材料とは別に保管す
ることができるので、広い冷蔵または冷凍保管設備を必
要としない。In addition, unlike the conventional prepreg method, there is no need to refrigerate or freeze the reinforcing fiber material impregnated with resin, and the resin material can be stored separately from the reinforcing fiber material. Does not require refrigeration or frozen storage facilities.
さらに、従来の樹脂含浸法のように、成形時に補強用繊
維材料に液状の樹脂を含浸する必要がないので、成形工
程の作業環境が良好である。Furthermore, unlike conventional resin impregnation methods, there is no need to impregnate the reinforcing fiber material with liquid resin during molding, resulting in a favorable working environment during the molding process.
