本発明は、ＳｉＣウィスカーにより強化する樹脂複合材
、とくに表面改質されたＳｉＣウィスカーを強化材とす
るＳｉＣウィスカー強化樹脂複合材の製造法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for producing a resin composite material reinforced with SiC whiskers, particularly a SiC whisker-reinforced resin composite material using surface-modified SiC whiskers as a reinforcing material. .
ＳｉＣウィスカーは、比強度、比弾性率などに優れ、ま
た熱的、化学的に安定であるため、各種樹脂材料の複合
強化物質として有用されている。SiC whiskers have excellent specific strength, specific modulus, etc., and are thermally and chemically stable, so they are useful as composite reinforcing materials for various resin materials.

要素となる。ところが、ＳｉＣウィスカーは本質的に樹
脂との濡れ性が悪く、また化学的に極めて安定であるた
め、マトリックス樹脂との結合性は良くない。In general, in order to use a fibrous reinforcing material to impart the expected composite performance to a resin, the reinforcing material must have good wettability with the matrix resin, and at the same time be strong through an interfacial chemical reaction with the matrix resin component. An important element is to combine them with each other. However, since SiC whiskers inherently have poor wettability with resins and are chemically extremely stable, they do not bond well with matrix resins.
このため、ＳｉＣウィスカーの表面性状を改質してマト

２−１１３８００号公報）が提案されている。For this reason, attempts have been made to improve the bonding properties with the matrix resin by modifying the surface properties of SiC whiskers. A surface modification method in which a thin film of stow is formed on the surface and then treated with a silane coupling agent.

しかしながら、ＳｉＣウィスカーの表面は化学的に不活
性であるため、そのままシランカップリング処理を施し
てもその反応基と化学結合し難く、十分なカップリング
効果を得ることができない。However, since the surface of SiC whiskers is chemically inert, even if they are directly subjected to silane coupling treatment, they are difficult to chemically bond with the reactive groups, making it impossible to obtain a sufficient coupling effect.
この点、ＳｉＣウィスカーの表面を予め酸化処理したの

ＯＨ基の反応性はさほど高くない関係で未だ十分な化学
結合を付与することが困難な問題がある。In this regard, the method of pre-oxidizing the surface of SiC whiskers and then subjecting them to silane coupling treatment considerably improves the bonding properties because the 10H groups formed on the surface increase the affinity with the reactive groups of the silane coupling agent. You can, but −
Since the reactivity of the OH group is not very high, it is still difficult to provide sufficient chemical bonds.

に設定し、樹脂の高分子鎖が有機溶媒中に均一相として
分散するまで静置するこが望ましい。A resin solution is prepared by dissolving a carbonizable resin such as a phenolic resin, a furan resin, or divinylbenzene in an organic solvent. It is desirable that the concentration of the resin solution be set in the range of 0.1 to 20% by weight, and allowed to stand until the polymer chains of the resin are dispersed as a homogeneous phase in the organic solvent.

理薬剤が良好に使用される。The oxidized carbon film is then surface-treated with a drug that has good reactive bonding properties with -COOH and -OH groups and has excellent reactivity or compatibility with the matrix resin. Therefore, the type of surface treatment agent must be selected depending on the matrix resin. For example, when using an epoxy resin as a matrix, diisocyanate and epoxy resin should be used together, diamine, etc., and polyamide resin or polyimide resin as a matrix. Surface treatment agents such as diamines and their compounds, urethane prepolymer polyethylene resins when using polyurethane resins as a matrix, and polyethylene grafted methyl acrylate when using polyolefin resins as a matrix are preferably used.
