摘要： PURPOSE:To obtain a material which totally satisfies low specific gravity, mechanical strength and heat resistance made of light-weight synthetic resin by using high polymer composite material whose specific gravity is a specific value or lower, bending strength is a specific value or higher, and glass transition temperature is a specific value or higher. CONSTITUTION:High polymer composite material whose specific gravity is 1.5 or less, bending strength is 12 kgf/mm and glass transition temperature is 260 deg.C or higher is used as an internal structural material 5 of a fan case 4 of a turbo fan engine. This high polymer composite contains preliminary reactant of polyamino compound with unsaturated bismuth imide compound, vinyl compound containing epoxy radical, aliphatic halogenized epoxy compound containing no vinyl radical, hardening agent for epoxy and radical copolymer initiator as essential components. Further, when the above preliminary reactant composed of thermosetting resin composition formed by preliminary reaction with substantially no existence of the above vinyl compound containing epoxy radical is used, the internal structural material 5 is light in weight, is heat- resistant for a long term and is excellent in mechanical strength.

摘要： PURPOSE:To produce the above composition which is tough, excellent in adhesion to glass cloth or metal and good in flexibility and heat resistance, by reacting a specified unsaturated bisimide with a diamine and a radical polymerization inhibitor by heating. CONSTITUTION:A diamine (a) of formula I (wherein B is a 30C or lower bivalent group) previously molten by heating is blended with an unsaturated bisimide (b) of formula II (wherein D is a bivalent group containing a C-C double bond, and A is a 2C or higher bivalent group), in an amount to give a molar ratio (b)/(a) of 0.9-1.5 and 0.01-5.0wt.%, based on the total of components (a) and (b), radical polymerization inhibitor (c) (e.g., hydroquinone). The resulting mixture is reacted by heating to 100-250 deg.C for several min to several hr in, optionally, an inert polar solvent (e.g., dimethylformamide).

摘要： PURPOSE:To obtain the projection screen which is wide in a light diffusion range in both horizontal and vertical directions and is bright by forming minute and dense undulation patterns with crossing in the horizontal and vertical directions on the surface of the metal aluminum layer provided on a substrate. CONSTITUTION:A metal aluminum layer is provided on a substrate surface. The undulation patterns of about 0.2S-25S in surface roughness (JIS B0601) having directivity in the horizontal direction and the undulation patterns of about 0.01S- 10S in surface roughness having directivity in the vertical direction are formed on the aluminum layer to provide the projection screen. It is desirable that the abovementioned horizontal undulation patterns be formed by rolling and the vertical undulation patterns be formed by mechanical surface treatment (polishing, brushing, etc.). The effect will be higher if many more crater-form patterns are given by etching or the like in addition to the abovementioned undulation patterns.

摘要： PURPOSE:To increase the mechanical strength and to improve the durability, by composing a grinding material with a matrix resin, grinding abrasive grain and fiber reinforcing material and increasing the grinding abrasive grain density of the inner layer rather than the outer layer. CONSTITUTION:Resin sheets 14c, 14d containing a fiber reinforcing material 4a and low density grinding abrasive grain 3a are arranged at both sides of the resin sheets 13a, 13b, 13c containing a high density grinding abrasive grain 3b. A desired grinding material is then obtained by hardening the resin by closing a forming mold having opposed recessed parts from the respective both sides.

摘要： PURPOSE:To readily make the screen which is of high luminance and is free from any glitter by subjecting the same to a directional uneven-patterning treatment by cylindrical polishing and a nondirectional uneven-patterning treatment by spray polishing. CONSTITUTION:When an aluminum foil of thickness 100mu or the like which is laminated and bonded onto a plastic plate is moved at a speed 20m/min. or other and is subjected to cylindrical polishing by a sandpaper polishing belt which is being rotated at the specified velocity of wind, the maximum heights assume the surface state of the required directional uneven pattern. Thence, when it is subjected to spray polishing by shot blasting of silica sand No.4 or the like, a nondirectional uneven pattern is formed and the direction and nondirection uneven patterns exist mixedly in the surface of the aluminum surface, thus the screen which is about 5.9 in luminance ratio at horizontal direction 30 deg., is about 3.8 or other in luminance ratio at vertical direction 10 deg., is high in luminance, is free from any glitter and is capable of performing projection under ordinary interior rays is readily made.
