本発明は優れた摺動特性と加工性に優れた炭素繊維強化
樹脂組成物に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a carbon fiber reinforced resin composition that has excellent sliding properties and processability.

いる。[Prior Art] Carbon fiber reinforced resin compositions are evaluated for their excellent mechanical properties and heat deformation temperature, and are used as friction-resistant and wear-resistant materials. However, for widespread use as friction-resistant and wear-resistant materials such as bearings, although the limit Pv value is high, the friction coefficient is not sufficient, and materials with lower friction coefficients are desired.

があった。Furthermore, in order to reduce the coefficient of friction, it has been proposed to blend crystalline polyolefin powder impregnated with carbon fiber and a liquid lubricant into a thermoplastic resin. (Unexamined Japanese Patent Publication No. 53-10
8142) [Problems to be Solved by the Invention] However, this proposal had the disadvantage that the mixing operation was complicated because it required a step of impregnating the crystalline polyolefin powder with the liquid lubricant. In addition, although the friction coefficient of the material proposed by this proposal is certainly lower, since it is impregnated with a liquid lubricant, the liquid lubricant may be liberated during processing, for example, when molded with an injection molding machine, resulting in the appearance of the molded product. It has the disadvantage that it contaminates the water to the extent that it has no commercial value.

発明を成すに至ったのである。[Means and effects for solving problem E] The inventors have surprisingly found that a carbon fiber-reinforced thermoplastic resin composition containing polyethylene having a specific weight average molecular weight has improved sliding properties and processability. They have found that both performance and performance are satisfied, and have come up with the present invention.

This was achieved for the first time using a thermoplastic resin composition.

る。The carbon fiber is not particularly limited, and bread-based or pitch-based carbon fibers made from polyacrylonitrile can be used.

る。ポリエチレンの形状は特に制限はなく、ペレット状
だけでなく、粉末状でもよい。The weight average molecular weight of polyethylene is in the range of 100,000 to 500,000, preferably 150,000 to 300,000. If the weight average molecular weight is less than 100,000, the improvement in sliding properties will be unsatisfactory, and if it is more than 500,000, the improvement in sliding properties will be unsatisfactory, and it will be difficult to uniformly disperse polyethylene. The shape of polyethylene is not particularly limited and may be in the form of not only pellets but also powder.

５重量部からなる組成物である。5 to 1 carbon fiber per 100 parts by weight of thermoplastic resin
The composition is composed of 30 parts by weight of carbon fiber and 3 to 60 parts by weight of polyethylene, but preferably 9 to 100 parts by weight of carbon fiber and 5 to 3 parts of polyethylene per 100 parts by weight of thermoplastic resin.
The composition consists of 5 parts by weight.
炭素繊維が５重量部より少ないと充分な機械的強度が得
られず、１３０重量部より多いと、溶融時の流動性が低
下し、加工性が劣るようになる。If the amount of carbon fiber is less than 5 parts by weight, sufficient mechanical strength cannot be obtained, and if it is more than 130 parts by weight, fluidity during melting will be reduced and processability will be poor.
ポリエチレンの量が３重量部より少ないと満足した摺動
特性が得られず、６０重量部より多いと、機械的強度の
低下を来たす恐れがある。If the amount of polyethylene is less than 3 parts by weight, satisfactory sliding properties may not be obtained, and if it is more than 60 parts by weight, there is a risk of a decrease in mechanical strength.
又、出熱のことながら、一般に知られた添加剤、耐候剤
