Example Embodiment
[0018] The technical scheme of the present invention will be further elaborated below in conjunction with the drawings and specific embodiments:
[0019] Such as figure 1 with figure 2 Shown: the present invention provides a reinforced, heat-insulating three-dimensional fabric, comprising an upper surface layer 1, a lower surface layer 2, and an intermediate layer 3 arranged between the upper and lower surface layers, the intermediate layer 3 includes spacer filaments 31 and a silica aerogel 32 doped with whiskers 321 or / and reinforced short fibers 322, the silica aerogel 32 is uniformly filled in several spaces formed by the arrangement of spacer filaments 31; The spacer wire 31 is W-shaped (such as figure 1 Shown) or X-shaped (such as figure 2 Shown) Arrangement structure.
[0020] As a preferred solution, a heat reflective coating 4 is provided on the upper surface layer or / and the lower surface layer to further reduce heat radiation and surface temperature.
[0021] As a pre...
