い。 FIG. 1a is an external view of an automobile roof according to an embodiment of the present invention, and FIG. 1b is a cross-sectional view taken along the line A--A. As shown in both figures, the roof 1 consists of a transparent plate 2, a foam structure 3, and an elastic body 4. Here, the transparent plate 2 is made of polycarbonate resin (for example, LEXAN
FL2000 (manufactured by EPL) is molded using heat press, vacuum, or injection molding, and is either colorless or transparent or colored. Further, the foamed structure 3 is made by injection molding a polycarbonate resin containing glass fiber or an inorganic filler as a foaming nucleating agent together with a chemical foaming agent or N2 gas. This molding is performed by attaching the transparent plate 2 in a mold and injecting the foamable polycarbonate resin together with a chemical foaming agent or N2 gas, and as the foamable polycarbonate resin foams, the transparent plate 2 and The foam structure 3 is integrally formed. Further, the elastic body 4 provided between the transparent plate 2 and the foamed structure 3 is not necessarily necessary, but is provided to prevent molding shrinkage between the transparent plate 2 and the foamed structure 3. A material with good heat resistance and low contamination property, such as silicone rubber, is used. In such a structure, the thickness of the foam structure 3 is 6 mm for strength reasons.
The thickness of the transparent plate 2 is preferably 1/2 or less.
このようなルーフ１においては、透明ポリカー
ボネート製の透光板２及び発泡製ポリカーボネー
ト製の発泡構造体の収縮・膨張率が略同じである
ため、完全に一体化されて防水性が完全であると
ともに、軽量・高剛性のものである。また、弾性
体４がインサートされているので、防水性がさら
に完全になつている。 In such a roof 1, since the contraction and expansion rates of the transparent plate 2 made of transparent polycarbonate and the foam structure made of foamed polycarbonate are approximately the same, they are completely integrated and have complete waterproofness. , lightweight and highly rigid. Furthermore, since the elastic body 4 is inserted, waterproofness is further improved.
本実施例のルーフ１には、必要に応じて外面に
塗装、内面に塗装、植毛表皮材の貼付などの２次
加工を施すことができる。 The roof 1 of this embodiment can be subjected to secondary processing such as painting the outer surface, painting the inner surface, and pasting a flocked skin material as necessary.
