Abstract: The present invention addressed the problem of providing a molded body which has a high performance of reducing energy caused by the application of a load, and which is obtained from a fiber-reinforced resin containing reinforcing fibers arranged while aligned in one direction. To solve the problem, the present invention relates to a molded body, including a reinforced layer formed by layering fiber-reinforced resin layers containing a plurality of reinforcing fibers arranged while aligned in one direction and a matrix resin impregnated with the reinforcing fibers. In the molded body, the reinforced layer has a plurality of alignment shifted layers, which are fiber-reinforced resin layers in which the shift angle, i.e., the angle formed by the reinforcing fibers with respect to the longitudinal direction of the reinforced layer, is 25° to 65° or ?65° to ?25°.

Abstract: A method to manufacture an extruded polystyrene resin foam includes the steps for heating and mixing a nucleating agent, a fire retardant, a polystyrene resin and a physical blowing agent except chlorofluorohydrocarbons together within an extruder to prepare a polystyrene resin melt; introducing the resin melt to a die having a cooling member therein and constructed so that a molten resin flow channel within the die is broad in a vertical direction but narrows abruptly near a die orifice ;and discharging the polystyrene resin melt from the die orifice into a guider attached to a top of the die and causing it to expand within the guider. The extruded foam has an apparent density of 0.015 to 0.06 g/cm3.

Abstract: A thick extruded polystyrene resin foam which can be obtained without using chlorofluorohydrocarbons has a center portion in which the cells are approximately spherical. The extruded polystyrene resin foam contains a residual gas selected from fluorohydrocarbons, aliphatic hydrocarbons and alicyclic hydrocarbons, and has a thickness of 45 to 150 mm and an apparent density of 0.015 to 0.06 g/cm3. The resin foam includes a center layer, excluding 10% of the foam thickness from each of the two foam surfaces, which is composed of cells with specific shape and compressive strengths in the foam thickness, transverse and machine directions.
