Abstract

The invention provides a resin composition containing glass fibers, wherein warping of a molded article is reduced and the resin composition has high transmittance, and a molded article using the same, a composition kit, and a method for producing a molded article. The resin composition is a polyamide resin composition containing a polyamide resin, glass fibers, an optically transparent dye, and muscovite.

Description

technical field [0001] The present invention relates to a method for producing a resin composition containing a polyamide resin, a molded article, a composition combination, and a molded article. The polyamide resin composition of the present invention is mainly used as a light-transmitting resin composition (light-transmitting resin composition) for laser welding. Background technique [0002] Polyamide resin, which is a representative engineering plastic, is easy to process, and has excellent mechanical properties, electrical properties, heat resistance, and other physical / chemical properties. Therefore, it is widely used in vehicle parts, electric / electronic equipment parts, other precision instrument parts, and the like. Recently, parts with complex shapes can also be made of polyamide resin. For example, in the bonding of parts with hollow parts such as intake manifolds, such as adhesive welding, vibration welding, ultrasonic welding, etc., can be used. Various claddi...
