Abstract

A resin formed article, comprising a main body that includes a first resin; a functional layer that is disposed at at least a portion of a surface of the main body and includes a fiber and a second resin; and a projection that is disposed on the functional layer and includes the first resin and the second resin.

Claims (16)

1 . A resin formed article, comprising:

a main body that includes a first resin;

a functional layer that is disposed at at least a portion of a surface of the main body and includes a fiber and a second resin; and

a projection that is disposed on the functional layer and includes the first resin and the second resin,

wherein a portion of the first resin is permeated into a portion of the functional layer, and wherein the projection does not include the fiber.

2 . The resin formed article according to claim 1 , wherein the first resin and the second resin each is a thermoplastic resin.

3 . The resin formed article according to claim 1 , wherein a melting temperature of the second resin is equal to or lower than a melting temperature of the first resin.

4 . A method for producing a resin formed article, the method comprising:

disposing a functional layer that includes a fiber and a second resin in a mold having a concave portion that corresponds to a projection of a resin formed article; and

supplying a first resin in a melted state to the mold,

wherein the second resin has a melting temperature that is equal to or lower than a melting temperature of the first resin, and

wherein a portion of the first resin permeates into a portion of the functional layer, and wherein the projection does not include the fiber.

5 . The method for producing a resin formed article according to claim 4 , wherein a portion of the second resin included in the functional layer is melted by contact with the first resin supplied to the mold.

6 . The method for producing a resin formed article according to claim 4 , further comprising pressurizing the first resin after the supplying the first resin to the mold.

7 . The method for producing a resin formed article according to claim 4 , wherein the first resin permeates through the fiber included in a basal region of the functional layer corresponding to a basal portion of the projection.

8 . The resin formed article according to claim 1 , wherein the first resin is permeated through the fiber included in a basal region of the functional layer corresponding to a basal portion of the projection.
