Abstract
Provided is a resin molded body capable of increasing a flexural modulus. A resin molded body according to the present invention includes a urethane resin, long reinforcing fibers, an inorganic filler having an average particle diameter of 1 μm or more, and fine inorganic particles having an average particle diameter of 200 nm or less, a content of the fine inorganic particles being 0.06 parts by weight or more and 3.00 parts by weight or less with respect to 100 parts by weight of the urethane resin.
Claims8
A resin molded body, comprising a urethane resin, long reinforcing fibers, an inorganic filler having an average particle diameter of 1 μm or more, and fine inorganic particles having an average particle diameter of 200 nm or less,
- a content of the fine inorganic particles being 0.06 parts by weight or more and 3.00 parts by weight or less with respect to 100 parts by weight of the urethane resin.
A method for producing a resin molded body, the method comprising:
- a mixing step of mixing a polyol compound, an isocyanate compound, an inorganic filler having an average particle diameter of 1 μm or more, and a thixotropic agent to obtain a first composition;
- an impregnation step of impregnating long reinforcing fibers with the first composition using an impregnation plate to obtain a curable resin composition;
- and
- a curing step of curing the curable resin composition in a mold,
- the thixotropic agent containing fine inorganic particles having an average particle diameter of 200 nm or less, and
- a content of the fine inorganic particles in the first composition being 0.06 parts by weight or more and 3.00 parts by weight or less with respect to 100 parts by weight of a total of the polyol compound and the isocyanate compound in the first composition.
