Abstract: PROBLEM TO BE SOLVED: To obtain a resin molded product having both of high physical properties by long fiber reinforcing effect and moldability equal to that in a case reinforced by short fibers by setting the shape parameter and measure parameter of the fiber length distribution of the resin molded product containing reinforcing fibers to specific ranges. SOLUTION: When a horizontal axis is set to the length of reinforcing fibers and a vertical axis is set to probability density, the shape of fiber length distribution has a specific distribution wherein short and long reinforcing fibers are arranged in this order and, when this distribution shape is formed so as to leave a gentle-sloping trail from short fibers to long fibers, the balance of the moldability and physical properties of a molded product is excellent. When a unit is set to mm and expressed by two-parameter Weibull distribution, the shape parameter of this distribution shape is 1-3 and the measure parameter βthereof is 0.23-3.

Abstract: PURPOSE:To obtain a fiber-reinforced phenolic resin formed article not having voids nearly at all by pultusion, by controlling both first and second dies to be at temperatures of the boiling point of water or below any by compounding a curing agent in an optimum range in phenolic resin to be used for impregnation in the first die. CONSTITUTION:Two dies 8 and 9 are used and the first die 8 is kept in a range of temperature not exceeding 50 deg.C, while the second die 9 is heated in a range of temperature of 50 to 80 deg.C. A reinforcing fiber material is introduced into the first die 8, while phenolic resin containing a curing agent in the range of 5 to 15 pts.wt. is supplied, and the reinforcing fiber material is impregnated with the resin. The reinforcing fiber material impregnated with the phenolic resin is drawn out of the first die 8 and introduced into the second die 9 and the phenolic resin is cured in the second die 9. The reinforcing fiber material used for forming is of carbon fibers and composed of ten plies of cloth of 100mm wide. The sheets of this cloth are piled and charged into the first die 8.

Abstract: PROBLEM TO BE SOLVED: To prevent a rolling stock from being damaged even when cut stringing is brought into contact with the roof of a rolling stock, by forming a roof whose structural body outside is formed with a conductive material layer and an electric insulation layer. SOLUTION: As a conductive material layer where a ground line 8 is brazed at the end part of a rolling stock structural body, a copper mesh 6a is bonded to the outer surface of a roof plate 3a with a phenolic resin adhesive 5b, and from the top side of the copper mesh 6a, room temperature curing 2-liquid mixing type urethane resin paint is applied. The liquid urethane rein paint is made to pass through the opening of the copper mesh 6a and penetrate to the surface of the roof 3a. The copper mesh 6a is coated with polyurethane resin paint film 5a as an electric insulation layer. It is thus possible to prevent a rolling stock from being damaged even when cut stringing is brought into contact with the roof of a rolling stock.
