［産業上の利用分野］
本発明は、自動車の外板や内装等に利用される繊維強化
プラスチック用強化繊維に係り、特に熱よる線膨張や外

繊維に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to reinforcing fibers for fiber-reinforced plastics used for automobile exterior panels, interior interiors, etc. This invention relates to reinforcing fibers for fiber-reinforced plastics.
［従来の技術］
一般に、自動車の内装等にはプラスチックが多用されて
いる。このプラスチックは耐蝕性、加工性に優れると共
に、特に自動車の軽量化手段としては不可欠なものであ
り、今日では、さらに鋼板が主流だったフェンダやボン
ネット等のプラスチック化も研究されている。[Prior Art] Generally, plastics are widely used in the interior of automobiles. This plastic has excellent corrosion resistance and processability, and is especially essential as a means of reducing the weight of automobiles.Today, research is also being conducted into using plastic for fenders, bonnets, etc., which were previously made of steel plates.

発生し、ドアｂとサイドフェンダａの接合部Ｃがカジリ
を起こし、ドアｂの開閉機能障害を誘発するといった間
組があつた。However, when automobile fenders, bonnets, etc. are made of plastic, it becomes necessary to combine and bond them with other steel plates. However, this plastic has a larger coefficient of linear expansion than other materials such as metals and ceramics, and this difference in coefficient of thermal expansion has the disadvantage of causing distortion at the joint with a steel plate or the like. Furthermore, in the case of large-area members such as fenders, the distortion is clearly visible to the naked eye, which not only impairs the beauty of the vehicle body, but also poses a problem in impact strength. For example, as shown in Figure 7, if the side fender a of a car is made of plastic, the side fender a will undergo thermal expansion deformation due to temperature changes, and the joint C between the door b and the side fender a will become stiff. There was an interruption that caused door b to open and close incorrectly.

チックの線膨張率を低くすると共に、プラスチック全体
の強度を向上させていた。Therefore, in the past, while increasing the strength of this plastic,
The most effective method for lowering the coefficient of linear expansion is to mix reinforcing fibers such as glass fibers into plastics. As shown in FIG. 5, this fiber-reinforced plastic d is formed by coating the surface of glass fibers e with a surfactant f to improve compatibility with the plastic g, and mixing it into the plastic g. This lowers the coefficient of linear expansion of the plastic and improves the overall strength of the plastic.

いった問題点があった。[Problems to be Solved by the Invention] However, since plastic and glass fibers are different materials, the conventional method does not allow sufficient compatibility between plastic g and glass fibers e, and the linear expansion coefficient still remains low. The difference cannot be resolved; for example, if an external force or sudden temperature change is applied to this fiber-reinforced plastic d, the glass fiber e and the plastic g will separate as shown in Figure 6, and this separated part will become There was a problem that cracks were caused and the durability of the entire fiber-reinforced plastic d was lowered.

This capsule fiber fItI3 is formed by adhering and fixing plastic powder 5 to the entire surface of glass fiber 4 and encapsulating it. Plastic powder 5 to this glass fiber 4
The adhesion and fixation is carried out by making the glasstic powder 5 into particles with a particle size of 10 μm or less, electrostatically adhering them to the glass fibers 4, and then fixing them by an impact method as shown in, for example, JP-A No. 62-250942. , capsule m-fiber 3. By encapsulating the glass fiber 4 in this way, unevenness is formed on the surface of the glass fiber, and this unevenness increases the adhesion between the plastic 2 and the capsule fiber 3, even when an external force F is applied, as shown in FIG. Peeling of the interface between the capsule fibers 3 is less likely to occur.
