Abstract
A resin composition comprising resin pellets comprising a first thermoplastic resin and glass fibers, and a second thermoplastic resin, in which the second thermoplastic resin has a lower flow starting temperature than the resin pellets, and a denier of the glass fibers is 500 g/1000 m or more and 3400 g/1000 m or less.
Claims9
A resin composition comprising:
- resin pellets comprising a first thermoplastic resin and glass fibers;
- and
- a second thermoplastic resin,
- wherein the first thermoplastic resin and the second thermoplastic resin are both liquid crystal polyester resins,
- the second thermoplastic resin has a lower flow starting temperature than the resin pellets,
- a length weighted average fiber length of the glass fibers is 5.5 mm to 20 mm,
- a denier of the glass fibers in the resin pellets is 500 g/1000 m or more and 3400 g/1000 m or less,
- each of the first thermoplastic resin and the second thermoplastic resin has a repeating unit (1) represented by Formula (1), a repeating unit (2) represented by Formula (2), and a repeating unit (3) represented by Formula (3), and
- a content of the repeating unit (2) is 10 mol % or more and 35 mol % or less with respect to a total amount of the repeating unit (1), the repeating unit (2), and the repeating unit (3),
- —O—Ar1—CO— (1)
- —CO—Ar2—CO— (2)
- —X—Ar3—Y— (3)
- wherein, Ar1 represents a phenylene group, a naphthylene group, or a biphenylylene group, Ar2 and Ar3 each independently represent a phenylene group, naphthylene group, biphenylylene group, or a group represented by Formula (4), X and Y each independently represent an oxygen atom or an imino group (—NH—), hydrogen atoms in the group represented by Ar1, Ar2, or Ar3 are each independently substituted with a halogen atom, an alkyl group, or an aryl group,
- —Ar4—Z—Ar5— (4)
- wherein, Ar4 and Ar5 each independently represent a phenylene group or a naphthylene group, and Z represents an oxygen atom, a sulfur atom, a carbonyl group, a sulfonyl group, or an alkylidene group.
