Abstract
Provided is a method for manufacturing a protection board. A reinforcement fabric including multiple reinforcement fibers is provided, each reinforcement fiber containing multiple adjacent filaments, each filament being composed of a core and a shell formed around the core, and a melting temperature of the shell is lower than a melting temperature of the core, the shell of each filament attached to the shell of the adjacent filament. The impact strength of the shell is higher than the impact strength of the core. The reinforcement fabric can be manufactured into a protection board with good impact resistance simply through heating and molding. Therefore, the reinforcement fabric has the advantage of both manufacturing a protection board with good impact resistance and reducing its process complexity and cost.
