Regarding polycarbonate resin compositions that are suitable for structural materials such as cameras and optical equipment, we have developed mold releasability without damaging the appearance of molded products. This invention relates to a glass fiber-reinforced polycarbonate resin composition that has improved impact strength, excellent rigidity, and has excellent moldability with little gas generation during molding. [Prior art and problems to be solved by the invention] Glass fiber-reinforced polycarbonate is used in various industrial fields, but as its uses expand, industrial parts with complex shapes are required, resulting in poor mold release and problems during molding. The lack of impact strength of the product has become a problem. For this reason, various types of lubricants have been added to improve mold releasability, but even if mold releasability is improved, the appearance may deteriorate, gas generation increases during molding, and mold damage occurs. Cleaning has increased and productivity has deteriorated. In addition, methods of blending isobutylene (Japanese Patent Publication No. 53-12946) and organopolysiloxane (Japanese Patent Publication No. 59-35929) have been used to improve impact strength. Even though the impact strength is not significantly improved, the appearance is significantly worse.

By doing so, impact strength can be improved without damaging the appearance.

品の外観を目視により評価したが、その判定基準は次の
通りである。Examples 1 to 13 As shown in Table 1, predetermined amounts of each component were blended and pelletized at 300°C using a twin-screw extruder. Using this pellet, injection molding was performed at 300°C to prepare a test piece, and the physical properties were measured. The results are shown in Table 1. The mold releasability evaluation was performed by molding a cylindrical molded product at 300° C. and using the hydraulic pressure (mold release hydraulic pressure) at which the ejecting pin of the molding machine protrudes the molded product. In this case, the lower the oil pressure, the better the mold releasability.
For practical purposes, it is good if the weight is 20 kg/cm2 or less. Further, the appearance of the molded product was evaluated by visual observation of the appearance of the cylindrical molded product used for mold releasability evaluation, and the criteria for evaluation were as follows.
×・・・ガラス繊維の浮き大
Δ・・・ガラス繊維の浮き中
Ｏ・・・ガラス繊維の浮き小
◎・・・ガラス繊維の浮き極小

It can be said that the lower the minimum filling pressure, the better the fluidity. The amount of gas generated was visually evaluated when it was injected into the air at 300°C. The judgment criteria are as follows.
×・・・ガス発生多い
△・・・ガス発生中くらい
Ｏ・・・ガス発生少ない
