- thermoplastic resins polycarbonate has excellent impact resistance, electrical properties, and moldability, and is widely used as an engineering plastic material capable of maintaining its physical properties over a wide temperature range and having self-extinguishing properties.
- brominated and chlorinated flame retardants are harmful to the human body due to the gases produced during combustion, and due to such human hazards, legal constraints are increasing, and impurities or by-products arising from brominated and chlorinated flame retardants are produced and used. This is undesirable because it can corrode related equipment.
- low molecular weight polycarbonate improves the moldability, but the impact and chemical resistance are drastically reduced, and when the core-shell impact modifier is added, the fluidity is decreased and due to excessive shear during processing.
- the desired impact resistance could not be obtained due to the destruction of the glass fiber and the deterioration of the resin, and the surface roughness due to the surface protrusion of the glass fiber was not good.

- the d) ethylene-containing acrylic resin has a problem in compatibility with polycarbonate resin if the content of ethylene is too high, and the impact reinforcing effect is lowered because the content of ethylene is too low, 20 to 60% by weight of ethylene based on the total weight of the resin %, Or in the range of 15 to 50% by weight.
- ethylene containing acrylic resin an ethylene-methylacrylate copolymer can be used as an example.

- Such glass fibers do not exhibit the required stiffness in the side feeder of the twin screw extruder, based on the total weight of the total monomers of the composition, of less than 10% by weight, and in excess of 50% by weight of flow and polycarbonate. Since the bonding strength with the resin is bad and the processing temperature is high and it is difficult to obtain the desired impact resistance and beautiful appearance, it can be added in the range of 10 to 50% by weight, or 25 to 50% by weight.

It showed high tensile strength and flexural modulus when reinforced with the same content, and showed excellent properties in fluidity, surface smoothness, and bending characteristics. This is because the flat glass fibers used in the present invention have a smaller number of glass fibers and a higher contact area with the matrix resin at the same content than the general cylindrical glass fibers.
