▎ 摘  要

NOVELTY - A functional composite material comprises functional surface layer and functional inner layer. The functional surface layer comprises polymer resin and antistatic agent. The functional inner layer comprises polymer resin and laser direct molding agent. USE - Functional composite material for communication, electronic, medical care, automobile and aerospace applications (claimed). ADVANTAGE - The functional composite material solves the problems in the existing product that the component resources of the laser direct forming agent in the non-laser activation area are wasted and the polymer components are prone to electrostatic damage. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the functional composite material, which involves (A) mixing and extruding polymer resin, antistatic agent and additive in a molten state, granulating, obtaining functional surface layer, (B) mixing and extruding the polymer resin, laser direct molding agent and additive in a molten state, granulating, obtaining functional inner layer, and (C) subjecting the functional surface layer and the functional inner layer to hot press molding, double-mold injection molding, multi-layer casting molding or welding.
