・xamethylenediamine, adipic acid, azelaic acid,
Sebacic acid and the like can be mentioned. Copolymerized nylon can be manufactured by a known method. The most common method is to heat ε-caprolactam and other copolymerization components while mixing them in the presence of water, distill off the water under pressure, and then polymerize under reduced pressure.

It is preferable that the relative viscosity at 25° C. is in the range of 1.5 to 6.0, more preferably 2.0 to 5.0. If the relative viscosity exceeds 6.0, the melt viscosity becomes too high and the fluidity of the resin composition deteriorates, which is not preferable. On the other hand, if the relative viscosity is less than 1.5, it provides only low mechanical strength, which is not preferable.
本発明でＣ成分として用いられるガラス繊維は熱可塑性

From long fiber type (glass roving) to short fiber type (
Any shape can be used, including chopped strands, milled fibers, and glass flakes.
中でも直径が３〜２０μｍ程度のガラス繊維は特に良好
な外観および機械的強度を与えるので好ましい。Among these, glass fibers having a diameter of about 3 to 20 μm are preferred because they provide particularly good appearance and mechanical strength.

Comparative Examples 1 and 2 Obtained from nylon 46 (KS400 manufactured by DSM, Netherlands) with a relative viscosity of 4.0, 90 mol% of ε-caprolactam, 5 mol% of bis(4-aminocyclohexyl)methane, and 5 mol% of isophthalic acid. Copolymerized nylon (relative viscosity 2.5) and chopped glass fiber strands with a diameter of 13 μm (Nippon Electric Glass Co., Ltd. 7289) were mixed in the proportions shown in Table 1, and after vacuum drying at 90°C for 16 hours, The mixture was melt-mixed at 300° C. using a twin-screw press ratio machine and cut into pellets. The obtained pellet was molded at 300° using an injection molding machine.
C to create a test piece. Using this test piece, surface gloss level, heat distortion temperature, tensile strength, and tensile modulus were measured. The results are also listed in Table 1.
（発明の効果） 本発明のガラス繊維強化樹脂組成物においては。(Effect of the invention) In the glass fiber reinforced resin composition of the present invention.
共重合ナイロンを特定贋金むことにより表面光沢が著し
く改良されており、しかも熱変形温度に代表される耐熱
性や機械的性質はそのまま保持されている。しかも引張
強度については予想に反して高い値を示している。The surface gloss is significantly improved by using a special coating of copolymerized nylon, and the heat resistance and mechanical properties represented by the heat distortion temperature are maintained as they are. Moreover, the tensile strength shows a higher value than expected.
