本発明の繊維強化複合材料用マトリックス樹脂およびプリプレグは、常温での保存安定性に優れ、低い温度で熱硬化できるため、繊維強化複合材料が安価かつ容易に成型でき、かつ、高い耐熱性を有した繊維強化複合材料を提供することができる。 Since the matrix resin and prepreg for fiber reinforced composite material of the present invention have excellent storage stability at room temperature and can be thermoset at low temperature, the fiber reinforced composite material can be molded easily at low cost and has high heat resistance. An improved fiber reinforced composite material can be provided.
本発明の（Ｂ）成分の形態は、以下に述べるマイクロカプセルに（Ｂ）成分を封入した形態である。
マイクロカプセル等により潜在性を付与することにより、さらに常温での保存安定性が
向上する。本発明でいう潜在性とは、製造工程でかかる温度である６０℃以下では硬化剤
としての作用をせず、それ以上の特定の温度、圧力、光量条件により硬化剤としての作用
を発現させる機能をいう。
Form of the component (B) of the present invention, Ru embodiment der encapsulating component (B) microcapsules described below.
Storage stability at room temperature is further improved by imparting latency with a microcapsule or the like. The term “latency” as used in the present invention refers to a function that does not act as a curing agent at a temperature of 60 ° C. or less, which is a temperature required in the production process, and develops an effect as a curing agent under specific temperature, pressure, and light quantity conditions. Say.
（Ｂ）成分が０．５質量部未満であると、硬化に必要な温度を１７０℃未満に低減することができないばかりでなく、硬化反応を十分に完了することができなくなる。
（Ｂ）成分が１０質量部を超えると、得られる樹脂組成物が高粘度となるため、強化繊維への含浸性が劣ってしまう。高粘度のマトリックス樹脂を強化繊維に含浸させるためには、通常より１０〜２０℃程度高い温度をかけて、マトリックス樹脂の粘度を下げる必要がある。その結果、製品に大きな熱履歴がかかり、保存安定性が失われてしまう懸念が生じる。また、この樹脂組成物を含浸して得られるプリプレグは、室温での保存安定性に欠ける。さらには、硬化温度の低減効果も弱まってしまう。
特に、本発明では上述した潜在性を付与した（Ｂ）成分を用いるため、（Ｂ）成分の含有量が本発明の範囲内であることが重要である。
When the component (B) is less than 0.5 parts by mass, the temperature required for curing cannot be reduced to less than 170 ° C., and the curing reaction cannot be completed sufficiently.
When the component (B) exceeds 10 parts by mass, the resulting resin composition has a high viscosity, so that the impregnation property to the reinforcing fibers is poor. In order to impregnate the reinforcing fibers with a matrix resin having a high viscosity, it is necessary to lower the viscosity of the matrix resin by applying a temperature about 10 to 20 ° C. higher than usual. As a result, there is a concern that a large heat history is applied to the product and storage stability is lost. Moreover, the prepreg obtained by impregnating this resin composition lacks the storage stability at room temperature. Furthermore, the effect of reducing the curing temperature is also weakened.
In particular, the present invention for use granted the potential described above component (B), it is important that within the scope of the present invention the content of the component (B).
次に、本発明の実施例について説明するが、本発明はこれらに限定されることはない。
