Manufacturing method of halogen-free flame-retardant thermoplastic braided fiber reinforced polymer composite board and product thereof

A manufacturing method of a halogen-free flame-retardant thermoplastic braided fiber reinforced polymer composite comprising steps of:

• (A) recycling a used material containing a halogen-free flame-retardant thermoplastic braided fiber reinforced polymer composite having a flammability rating of UL94 V-0;
• (B) adding a polymer base material to the recycled used material to form a core layer material and extruding the core layer material with a low shear extruder;
• (C) hot pressing the core layer material by rollers to obtain a recycled fiber core layer;
• (D) preparing a reinforcement layer containing a fiber material or a fabric with pores;
• and
• (E) stacking and hot pressing the recycled fiber core layer and the reinforcement layer to cause the halogen-free flame-retardant thermoplastic braided fiber reinforced polymer composite of the recycled fiber core layer penetrating into the pores of the reinforcement layer to form a composite board in which dissimilar materials of recycled fiber core layer and the reinforcement layer are linked with each other.
