Embodiment
[0017] figure 1 It is a cross-sectional view of a highly transparent porous quartz / quartz ceramic matrix composite material. Among them, [10] is a quartz / quartz composite material layer composed of quartz fiber reinforcement and quartz matrix, and [20] is a channel, which is characterized in that the channel is uniformly present in the part of the quartz / quartz ceramic matrix composite near the inner surface. The channel is circular with a diameter of 1 mm, and the distance between the channel layer and the inner surface is 5 mm. The volume ratio of pores to the whole material is 20%. The shape of the channels is linear, and the channels are distributed parallel to each other.
[0018] The preparation method of the above-mentioned highly transparent porous quartz / quartz ceramic matrix composite material, the specific steps are as follows:
[0019] (1) The pure iron wire is prefabricated in the reinforced structure formed by quartz fiber weaving or lamination, and the pure i...
