A cartridge type hollow fiber membrane module including a housing, a hollow-fiber membrane bundle having a plurality of hollow fiber membranes, a first potting part that bonds the hollow fiber membranes at at least one end of the bundle of the plurality of hollow fiber membranes such that the hollow fiber membranes are open, and a sealing material that fixes the first potting part to the housing liquid-tightly, wherein the first potting part comprises an inner potting part and an outer potting part, wherein the inner potting part and the outer potting part are both formed of a potting material, wherein the sealing material is in contact with the outer potting part, and wherein both the inner potting part and the outer potting part are formed in a sealing direction of the sealing material. The cartridge type hollow fiber membrane module is free of leakage and contamination due to separation of a potting material even when steam sterilization is performed.

A process for producing a sheet-shaped prepreg includes: a fiber bundle introduction step in which tape-shaped reinforcing fiber bundles are disposed in a multilayer arrangement in the thickness direction and introduced into a die to which a molten thermoplastic resin has been supplied; a fiber bundle thickness reduction step in which each of the tape-shaped reinforcing fiber bundles is widened by means of spreading to reduce the thickness; a resin impregnation step in which the tape-shaped reinforcing fiber bundles are impregnated with the molten resin in the die; and a lamination step in which the plurality of resin-impregnated tape-shaped reinforcing fiber bundles are laminated in the die.
