この発明は、特に赤外線から可視光線領域の光線を反射

。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention relates to a fiber-reinforced plastic reflector that reflects light in the infrared to visible light range, in particular.

下地層7が設けられている。Figure 3 shows a conventional fiber-reinforced plastic board (hereinafter referred to as F) of this type.
1 is a cross-sectional view of a reflecting mirror (referred to as RP);
The core material is made of woven foam or polymer foam.
Made from lightweight and highly rigid FRP board. Reference numeral 2 denotes a carbon FRP board bonded to both sides of the core material 1 with an adhesive 3, and the core material 1 and the carbon FRP board 2 have a curved shape as a whole. Reference numeral 4 denotes a reflective film formed by vapor deposition or the like on the surface of the carbon FRP plate 2 on the concave side. Incidentally, reference numeral 5 denotes a support member made of an FRP beam that supports the reflecting mirror configured as described above via an FRP support beam 6. FIG. 4 shows another embodiment of the conventional FRP reflector, in which a hard material such as glass is used on the surface of the carbon FRP plate 2 on which the reflective film 4 is applied in the reflector shown in FIG. A smooth base layer 7 is provided.
上記のように構成された反射鏡は、凹面側のFRP板2
表面に施こされた反射膜4に赤外線から可視光線領域の
光線を反射させることができる。The reflecting mirror configured as described above has an FRP plate 2 on the concave side.
The reflective film 4 applied to the surface can reflect light in the infrared to visible light 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、水平。Since the conventional FRP reflector is configured as described above, if the core material 1 is a honeycomb core, it is horizontal.
垂直面内の機械的、熱的特性が等しくないため、例えば
鞍型の成形歪や熱変形が生じる。しかも、ハニカムコア
を分割してコアの水平方向、垂直方向を考慮して配置し
ても分割したコア内での異方性は残る。また分割数を増
加してもシートを接着し展張してへ二カムコアを成形す
る限り、コアの異方性は除去されず、不均一な成形歪や
熱変形を生じることになる。さらにコアの分割はコアの
不連続性による鏡面の変形も加わる。この結果、光線を
反射鏡で反射し結像する場合、像のぼやけが生じたり、
また、反射鏡の焦点くある点光源より発せられた光線を
反射鏡で反射しても均一な分布の平行光線とならない。Because the mechanical and thermal properties in the vertical plane are not equal, saddle-shaped molding distortion and thermal deformation occur, for example. Moreover, even if the honeycomb core is divided and arranged in consideration of the horizontal and vertical directions of the core, anisotropy remains within the divided core. Furthermore, even if the number of divisions is increased, as long as the sheets are bonded and stretched to form a hemi-cam core, the anisotropy of the core will not be removed, resulting in non-uniform molding distortion and thermal deformation. Furthermore, splitting the core also adds deformation of the mirror surface due to core discontinuity. As a result, when the light beam is reflected by a reflecting mirror and formed into an image, the image may become blurred or
Furthermore, even if the light rays emitted from a point light source at the focal point of the reflecting mirror are reflected by the reflecting mirror, they will not become parallel rays with a uniform distribution.
一方、芯材1が均質な高分子発泡体の場合、機械的、熱
的特性は等1的ではあるが、熱膨張率が3〜7 X 1
0−5/’Cであるため反射鏡の熱変形量がハニカムコ
ア芯材の場合より大きくなる。On the other hand, if the core material 1 is a homogeneous polymer foam, the mechanical and thermal properties are uniform, but the thermal expansion coefficient is 3 to 7 x 1.
Since it is 0-5/'C, the amount of thermal deformation of the reflecting mirror is larger than that of the honeycomb core core material.

れたもので、不均一な変形がなく、しかも変形量の小さ
い高精度なFRP製反射鏡を得ることを目的とする。This invention was developed in order to solve the above-mentioned problems, and its object is to obtain a high-precision FRP reflecting mirror that is free from non-uniform deformation and has a small amount of deformation.

。The FRP reflector in this invention uses a low-density, homogeneous inorganic porous material or foam material, or a hardened resin material containing micro hollow bodies, which has uniform mechanical and thermal properties as the core material. This results in a highly accurate reflecting mirror that is lightweight and has high rigidity, and is free from uneven molding distortion and thermal deformation.
