Abstract
A grooved resin molded part which when joined to another molded part, can form a composite molded product having an enhanced strength. This part contains an inorganic filler and has multiple grooves formed by partially removing the resin, such that the filler is exposed in these grooves. The depth of the grooves may be at least one-half of the length of the grooves in the shorter direction. The filler may have a fibrous shape; and the longer direction of the filler may be different from that of the grooves. The part is obtained by subjecting a resin molded part containing the filler to laser irradiation or the like to form multiple grooves in which the filler is exposed.
Claims24
A grooved resin molded article containing an inorganic filler and comprising at least one groove in which the inorganic filler is exposed, wherein the inorganic filler bridging protrusions are present at both sides of the at least one groove.

(canceled)
A method of manufacturing a grooved resin molded article, the method comprising a groove forming step of performing partial removal of a resin in a resin molded article containing a fibrous inorganic filler to form a groove in which the inorganic filler is exposed from a side surface thereof,
- wherein the length of the fibrous inorganic filler in the longer direction is longer than that of the at least one groove in the shorter direction, and
- the at least one groove having a width shorter than the length of the fibrous inorganic filler in the longer direction is formed in a direction different from the longer direction of the fibrous inorganic filler in the groove forming step.
19-21. (canceled)
24-26. (canceled)
A grooved resin molded article containing an inorganic filler, and
- comprising at least one groove in which the inorganic filler is exposed, the longer direction of the inorganic filler being different from that of the at least one groove, and
- the length of the at least one groove in the shorter direction being shorter than that of the inorganic filler in the longer direction.
A method of manufacturing a composite molded article, the method comprising preparing a grooved resin molded article by a groove forming step of performing partial removal of a resin in a resin molded article containing an inorganic filler to form a groove in which the inorganic filler is exposed from a side surface thereof, and then
- Integrating the grooved molded article with another molded article by injection molding through a surface having the at least one groove arranged as a contact surface to manufacture the composite molded article.
