Reinforcement fabric, protection board, and method for manufacturing the protection board

A method for manufacturing a protection board, comprising steps of:

• providing a raw fabric made of a reinforcement fabric, the reinforcement fabric comprising multiple reinforcement fibers, each reinforcement fiber containing multiple adjacent filaments, each filament composed of a core and a shell formed around the core, a melting temperature of the shell being lower than a melting temperature of the core, and the shell of each filament attached to the shell of the adjacent filament, and the impact strength of the shell being higher than the impact strength of the core;
• heating the raw fabric to melt the shell to obtain a melted raw fabric;
• molding the melted raw fabric to obtain an untreated protection board;
• depositing aluminum on a surface of the untreated protection board to obtain a raw protection board;
• and
• applying a thermoplastic polyurethane to a surface of the raw protection board to obtain the protection board;
• wherein the protection board comprises:
• a base made of the shells of the filaments in the reinforcement fiber;
• multiple reinforced portions arranged at spaced intervals in the base, and each reinforced portion comprising the cores of the reinforcement fibers of the reinforcement fabric;
• and
• a thermoplastic polyurethane layer, made by the thermoplastic polyurethane and coated on a surface of the base.
