るｌａ！補強樹脂組成物に関するものである。Detailed Description of the Invention [Industrial Field of Application] The present invention relates to a fiber-reinforced resin composition, particularly in fields where dimensional stability and weather resistance at high temperatures are required, such as fenders and door panels. , la! is used for vehicle exterior parts such as bumpers, bumper skirts, and fascias. The present invention relates to a reinforced resin composition.
フィラー等で補強されたプロピレン系樹脂組成物は、そ

広く使用されている。Propylene-based resin compositions reinforced with fillers, etc. have excellent moldability and physical properties, and are economically advantageous, so they are widely used in the field of automobile parts and various other industrial parts. .
ところが、前記補強のためのフィラーとして炭酸カルシ
ウムや硫酸バリウムを用いた場合には、高温時の寸法安
定性が不充分である。However, when calcium carbonate or barium sulfate is used as the reinforcing filler, the dimensional stability at high temperatures is insufficient.
また例えば、ガラス繊維をフィラーとして用いた場合に
は高温時の寸法安定性は良くなるが、成形反りや物性低
下、特に衝撃強度の低下という問題を生ずる。For example, when glass fiber is used as a filler, the dimensional stability at high temperatures is improved, but problems such as molding warpage and deterioration of physical properties, particularly impact strength, occur.
これらの問題を解決する手法としては、フィラーとして

８号、特開昭５９−１４０２４５号、特開昭５８−２１
３０３２号、各明細書参照）。As a method for solving these problems, a reinforcing method using fine Ta fibers (whiskers) as a filler has been proposed. Among them, products using fine fibers of potassium titanate as a filler not only improve dimensional stability and mold warping at high temperatures, but also have excellent physical properties, so they can be used not only for propylene-based plastics but also for various other plastics. A number of reinforcement materials have been proposed for use in combination with fillers (for example,
