[0021] In this embodiment, an elastomer intermediate layer 103 and a nanofiber reinforcing layer 104 are disposed between the first base layer 101 and the second base layer 102. Hot pressing is used to composite the elastomer intermediate layer 103 and the nanofiber reinforcing layer 104 with the first base layer 101 and the second base layer 102. During the hot pressing process, under the influence of pressure and temperature, the molecules of the elastomer intermediate layer 103 and the nanofiber reinforcing layer 104 diffuse and entangle with the first base layer 101 and the second base layer 102, forming strong chemical bonds and physical adsorption. This tightly binds the materials into a whole, improving the bonding force and thus enhancing the strength and toughness of the glass fiber wet-laid mat structure 1.
