Referring to fig. 1, a method for manufacturing a terminal protection cover according to a first embodiment of the present disclosure may include the following steps:
step S101: filling the surface of a Kevlar (aramid fiber material) structure with the thickness of less than or equal to 0.2 mm;
the untreated kevlar structure is similar to cloth, the surface has a plurality of holes (the diameter of the holes is smaller than a specific threshold), and the hardness and the density of the kevlar structure cannot meet the requirements, so that the kevlar structure with higher hardness and higher density can be obtained by filling the surface of the kevlar structure, namely filling the holes on the surface of the kevlar structure. In this embodiment, the hardness of the kevlar structure after the filling treatment is greater than the specific hardness value, and the density of the kevlar structure after the filling treatment is greater than the specific density value, so as to ensure that the hardness and the density of the manufactured protective sleeve meet the requirements.
The way of filling the kevlar structure may include various ways, for example, in one embodiment, referring to fig. 2, the kevlar structure with a thickness of less than or equal to 0.2mm is soaked in the resin with a temperature greater than or equal to a specific temperature threshold. Wherein, when the temperature of the resin is less than a specific temperature threshold, the resin is in a solid state; and when the temperature of the resin is higher than a specific temperature threshold value, the resin is in a liquid state.
