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°.

Molded body and method for manufacturing same

This invention relates to a preparation for a polyurethane foam and a polymer polyol preparation for a polyurethane foam, each of which exhibits high coloration and discoloration inhibition properties over a long period of time when stored, and to a composition for a polyurethane foam, which is excellent in storage stability and is preferable as a resin premix. The composition comprises (i) at least one polyol, (ii) a compound having a P&#x2550;N bond, (iii) an antioxidant having a hydroxyphenyl group, (iv) at least an acid and/or its salt, (v) a catalyst for polyurethane foam production and (vi) a blowing agent.

The present invention provides a polyester polyol, preferably a plant-derived polyester polyol, suitable for a composition for polyurethane foam that contributes to the reduction of load on the environment and has a good balance of high resilience, moderate hardness, and high durability as a cushioning material for vehicle seat cushions. A polyester polyol having a hydroxyl value in the range of 15 to 100 mgKOH/g according to the present invention is produced by a condensation of raw materials comprising at least one selected from the group consisting of fatty acids having a hydroxy group and fatty acid esters having a hydroxy group with a polyhydric alcohol having an average number of functional groups of more than three but not more than eight. The raw materials contain 90% to 100% by mass of a fatty acid having a hydroxy group and a fatty acid ester having a hydroxy group in total.

Disclosed are a polyol with a molecular weight distribution Mw/Mn of 4 or more, obtained by reacting a compound comprising an alkylene oxide compound (II) having a hydroxyl group in a base polyol (I) with a molecular weight of 2000 or more; and a polyol composition for a flexible polyurethane foam, comprising a polyol compound and a crosslinker, wherein the crosslinker comprises a polyol (a) with a hydroxyl value of 50 to 1100 mgKOH/g and with a primary hydroxylate ratio of 25% or more and 60% or less, which is obtained by an addition of a compound comprising alkylene oxide compound (ii) having a hydroxyl group to active hydrogen compound (i).

Polyol, polyol composition, and flexible polyurethane foam using the same

Highly-functionalized, low-viscosity polyether polyols are obtained by dehydration condensation reaction of alcohols. The polyether polyols are obtained by dehydration condensation of glycerin and monohydric and/or dihydric alcohol with the glycerin percentage being more than 50 mol % relative to 100 mol % of the total of the glycerin and alcohol. The glycerin may be crude glycerin obtained by hydrolysis or alcoholysis of natural fat and oils.
