Document Type and Number:
Japanese Patent JPH04170435
Kind Code:
A
Abstract:
PURPOSE:To obtain the title compsn. having good physical properties with an excellent processability under a stable feeding by compounding a thermoplastic resin with a short carbon-fiber aggregate surface-coated with an epoxy sizing agent emulsion having a specified mean particle diameter. CONSTITUTION:100 pts.wt. thermoplastic resin is compounded with 5-40 pts.wt. short carbon fiber aggregate surface-coated with a sizing agent emulsion mainly comprising an epoxy compd. and having a mean particle diameter of 0.3-1mum, pref. 0.4-0.6mum, (the amt. of the agent attached to the aggregate being 0.1-10wt.% based on the total wt.). giving the title compsn. A mixture comprising 45-95wt.%, pref. 45-65wt.%, epoxy compd. which is liq. at room temp (e.g. an epoxy compd. of a bisphenel A type having a mol.wt. of 470 or lower) and 5-45wt.%, pref. 35-45wt.%, epoxy compd. which is solid at room temp. (e.g. an epoxy compd, of a bisphenol A type having a mol.wt. of 900-5000) is pref. as the epoxy compd.
