Example Embodiment

[0024] Example 1

[0025] The glass fiber reinforced polyether ether ketone 3D printing consumable of the present invention is composed of long glass fiber (GL), PEEK resin viscosity modifier and PEEK resin. The components are long glass fiber (GL) with a mass percentage of 15% and PEEK resin viscosity. The mass percentage of the regulator is 2%, the mass percentage of PEEK is 83%, the melt index of PEEK is 8, the tensile modulus of long glass fiber (GL) is 81 GPa, and the viscosity regulator of PEEK resin is polyaryletherketone liquid crystal polymer.

[0026] The glass fiber reinforced polyether ether ketone 3D printing consumable of this embodiment solves the problem of the limitations of traditional 3D printing consumables, and increases the application of consumables in terms of high heat resistance, high strength, high modulus, and high fracture toughness. Directly replace metal for the manufacture of various complex components, the products are cheap and lightweight, so that...

Abstract

The invention provides a glass fiber reinforced poly(ether-ether-ketone) 3D printing consumptive material and a preparation method thereof, wherein the glass fiber reinforced poly(ether-ether-ketone) 3D printing consumptive material is formed by mixing long glass fiber (GL), a poly(ether-ether-ketone) (PEEK) resin viscosity modifier, and a PEEK resin. The preparation method comprises: raw material drying, melting extrusion, cooling, traction, and winding. According to the present invention, by adding the PEEK resin viscosity modifier to the PEEK, the viscosity of the PEEK matrix resin can be effectively reduced so as to be suitable for the processing of the 3D consumptive material; the PEEK resin viscosity modifier is formed from the polyetherketoneketone liquid crystal polymer having the structure similar to the poly(ether-ether-ketone), such that the compatibility with the poly(ether-ether-ketone) matrix resin is solved due to the similar structure; and the PEEK is the special engineering plastic, and can be combined with the 3D printing molding method, such that the obtained material can be used for preparing the complex functional member so as to expand the material application field.

Description

technical field [0001] The present invention relates to a 3D printing consumable, in particular to a glass fiber reinforced polyether ether ketone 3D printing consumable and a preparation method thereof. Background technique [0002] In the development of 3D printing manufacturing technology, materials are the key to technology improvement. 3D printing manufacturing technology is a brand-new manufacturing concept, which will eventually be applied to large-scale intelligent production in large industries. Nowadays, due to the limitation of the strength of plastic itself, the application of plastic materials in 3D printing is limited to ordinary products. In the future, plastic materials will develop towards high strength. With its excellent comprehensive properties such as high heat resistance, high strength, high modulus, and high fracture toughness, PEEK is considered to be the most likely material to directly replace metals in the manufacture of various complex component...
