Abstract
Claims
1. A continuous fiber resin composite comprising (A) polyamide, (B) organic phosphinate, (C) filler having an isoelectric point of 5 or less, and (D) continuous reinforcing fibers, The content of (B) the organic phosphinate is 0.5 to 20% by mass relative to 100% by mass of the continuous fiber resin composite. A continuous fiber resin composite in which the content of filler having an isoelectric point of 1.5 or more and 5 or less is 0.01% by mass or more and 2% by mass or less based on 100% by mass of the continuous fiber resin composite.
2. The continuous fiber resin composite according to claim 1, wherein 0 to 30% by mass of the polyamide (A) consists of a semi-aromatic polyamide.
3. The continuous fiber resin composite according to claim 1 or 2, wherein the (B) organic phosphinate is aluminum diethylphosphinate.
4. The continuous fiber resin composite according to any one of claims 1 to 3, wherein the filler having an isoelectric point of 5 or less is carbon black.
5. The continuous fiber resin composite according to any one of claims 1 to 4, wherein the volume ratio Vf of the continuous reinforcing fibers (D) is 40% or more.
6. (E) The continuous fiber resin composite according to any one of claims 1 to 5, further comprising a phosphate salt.
7. The continuous fiber resin composite according to claim 6, wherein the (E) phosphate is aluminum phosphite.
8. The continuous fiber resin composite according to any one of claims 1 to 5, wherein the product of the mass percentage of (B) the organic phosphinate and the mass percentage of (C) the filler having an isoelectric point of 5 or less is 0.1 to 2.
9. The continuous fiber resin composite according to claim 6 or 7, wherein the product of the total mass % of (B) organic phosphinate and (E) phosphate and the mass % of (C) filler having an isoelectric point of 5 or less is 0.1 to 2.
