化プラスチック(以下、CFRPという)板からなる。Figures 4 and 5 are cross-sectional views of another conventional fiber-reinforced plastic (hereinafter referred to as FRP) backing mirror. In Figure 2, (1) is made of honeycomb core or polymer foam. The core material (2) is a layering agent (

その表面に施されている。(4) is a reflective film formed by vapor deposition on the reflective surface of the FRP board (2), (5) is a support that supports the reflective mirror, and (6) is the FRP board (2) that does not serve as a reflective surface. This is a reflex theory support book that is attached to a support (5). In FIG. 4, a hard and smooth base layer (such as glass or metal) of glass or metal is formed on the surface of an FRP plate (2) serving as a 2-reflecting surface, and a 2-reflecting film (4) is applied to that surface.

The reflective film (4) provided on the surface of the FRP board (2) reflects light in the infrared to ultraviolet range.

結像する場合、像のぼやけが生じたシ、また2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。Since the structure is similar to that of a conventional PRP counter-reflector, if the core material (1) is a non-nicum core, the mechanical and thermal properties in one plane are not isotropic, so for example, saddle-shaped molding distortion may occur. or thermal deformation may occur. Even if the Nicum core is divided and arranged with directionality in mind, anisotropy remains within the two divided cores, and uneven molding strain and thermal deformation cannot be completely eliminated. 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 two reflecting mirrors 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
な変形は生じないが、線膨張率が3〜7 X 10−5

チ板としての剛性対重量を考えた場合。On the other hand, if the core material (1) is a homogeneous polymer foam, non-uniform deformation will not occur, but the coefficient of linear expansion will be 3 to 7 x 10-5.
/°C (for example, in the case of aluminum lamino-nicum core), thermal deformation generally becomes large. Furthermore, when considering the stiffness versus weight as a sand inch board.
高分子発泡体はハニカムコアを芯材(1)としたものよ
シ劣るなどの問題点があった。Polymer foams had problems such as being inferior to those using honeycomb cores as the core material (1).
