This is a reflector support body which is attached to a support body (5). In Fig. 4, a hard and smooth base layer (7) of glass or metal is formed on the surface of an FRP plate (2) that becomes a reflective surface, and a reflective film (4) is formed.

A reflective film (4) applied to the surface of the RP board (2) reflects light in the infrared to ultraviolet range.
従来のＦＲＰ製反射鏡は以上のように構成されているの
で、芯材（１）がハニカムコアの場合、面内の機械的、
熱的特性が等方でないため１例えば鞍型の成形歪や熱変
形が生じる。ハニカムコアを分割し、方向性を考慮して
配置しても、分割したコア単体内での異方性は残り、不
均一な成形歪や熱変形を完全になくすことはできない。Conventional FRP reflective mirrors are constructed as described above, so when the core material (1) is a honeycomb core, in-plane mechanical,
Since the thermal properties are not isotropic, for example, saddle-shaped molding distortion and thermal deformation occur. Even if the honeycomb core is divided and arranged with directionality in mind, anisotropy remains within each divided core, and uneven molding strain and thermal deformation cannot be completely eliminated.
さらにコアを分割する場合、コア分割部分の不連続性に
よる鏡面の変形も加わる。この結果、光線を反射し結像
する場合、像のぼやけが生じたり、また、反射鏡の焦点
にある光源より発せられた光線を反射しても、均一な強
度分布の平行光線とならない。Furthermore, when the core is divided, the mirror surface is deformed due to the discontinuity of the core divided portion. As a result, when a light beam is reflected to form an image, the image becomes blurred, and even when the light beam emitted from the light source at the focal point of the reflecting mirror is reflected, it does not become a parallel light beam with a uniform intensity distribution.
一方、芯材（１）が均質な高分子発泡体の場合、不均一

ニカムコアを芯材（１）としたものより劣るなどの問題
点があった。On the other hand, if the core material (1) is a homogeneous polymer foam, non-uniform deformation will not occur, but the linear expansion coefficient will be 3 to 7X10-'/
℃, the thermal deformation is generally larger than in the case of, for example, an aluminum honeycomb core. Furthermore, when considering rigidity versus weight as a sandwich board, polymer foams have problems such as being inferior to those using a honeycomb core as the core material (1).

．． A homogeneous porous ceramic with a weight of 3 to 1.0 g/cJ is used, FRP plates are fixed to both sides of the ceramic, and a reflective film is formed on the reflective surface of the FRP plate.

成形歪や熱変形がなく、軽量化された高精度な反射鏡が
得られる。The FRP reflector in this invention has a homogeneous core material, isotropic mechanical and thermal properties, and is a low-density porous ceramic with a coefficient of linear expansion smaller than that of polymer foam, so it can be molded non-uniformly.
