[Prior Art] Conventionally, composite materials in which various resins are reinforced with glass fibers have been used in various fields. It has been studied to use polypropylene resin reinforced with glass fiber, but polypropylene resin is a non-polar resin, so that it has a problem that it has poor affinity with glass fiber. Therefore, it is impossible to obtain satisfactory mechanical properties simply by mixing the polypropylene resin and the glass fiber. Therefore, for example, JP-A-57-76041 discloses a composition in which a polypropylene resin, a resin component obtained by mixing a modified polypropylene resin modified with an unsaturated carboxylic acid or a derivative thereof, and glass fiber are mixed. Has been done.
It is known that the use of this modified polypropylene resin improves the interfacial adhesion between the polypropylene resin and the glass fiber and improves the strength, rigidity, heat resistance and the like.

[Problems to be Solved by the Invention] By the way, the effect of the modified polypropylene resin is not significant unless the polypropylene resin is added in a relatively large amount. For example, the addition amount of the modified polypropylene resin generally required is 10 to 20% by weight based on 80 to 90% by weight of the polypropylene resin. Modified polypropylene resin is 10
If the amount is less than the weight%, the affinity with the glass fiber becomes poor and the strength, heat resistance and the like are deteriorated. However, according to the research conducted by the present inventors, it has become clear that the elastic modulus of the composite material containing glass fibers decreases when the modified polypropylene resin is added in an amount of 10% by weight or more in all the resin components. Further, the modified polypropylene resin is expensive because the manufacturing method is difficult, which is a factor of cost increase.

As the glass fiber, those having any shape from a long fiber type (glass low bean) to a short fiber type (chopped strand, milled fiber) can be used. Of these, chopped strands are the most preferable. As this glass fiber, one that has been previously treated with a silane coupling agent is used. The glass fiber content is 2 to 40 parts by weight with respect to 60 to 98 parts by weight of the resin component. If the glass fiber is less than 2 parts by weight, the reinforcing effect is poor,
If it exceeds 40 parts by weight, the fluidity at the time of molding and the appearance quality of the molded product deteriorate.

Where it is.
This monomer component may be used alone or in combination of two or more. The same unsaturated carboxylic acid and unsaturated carboxylic acid derivative as those exemplified above can be used. Of these, maleic anhydride gives good results. When the amount of the monomer component blended is less than 0.05 parts by weight, the affinity with the glass fiber becomes poor and the performance of the obtained composite material deteriorates. On the other hand, if the amount is more than 1 part by weight, the strength of the composite material is not significantly reduced, but the adverse effect of the monomer components may cause pinholes, silver phenomena, etc. in the obtained molded product to deteriorate the appearance quality.
