Abstract
The invention discloses a carbon fiber-reinforced compressed graphite tube. Raw materials for production of the carbon fiber-reinforced compressed graphite tube comprise the following components, by mass, 12-18% of glass fiber, 18-22% of a phenolic resin, and 60-70% of graphite powder. According to the carbon fiber-reinforced compressed graphite tube of the present invention, carbon fiber is added in the production process so as to improve mechanical properties of the compressed graphite tube.
Description
Technical field
The present invention relates to be used for the die mould carbon tube of graphite equipment, be specifically related to a kind of thomel and strengthen the die mould carbon tube.
Background technology
Traditional die mould carbon tube is formed through hot extrusion by HV resol and Graphite Powder 99, supplies the graphite industry to install and use.Tradition die mould carbon tube material consists of: the resol mass percent is approximately 23%; The Graphite Powder 99 mass percent is approximately 77%, and mechanical property was smaller after manufacturing was accomplished, with internal diameter 22mm; External diameter 32mm is example: tensile strength 20MPa, bending strength 250MPa.
Summary of the invention
Goal of the invention: the present invention provides a kind of tensile strength and bending strength bigger thomel fiber reinforcement die mould carbon tube in order to solve the deficiency of prior art.
The technical scheme that the present invention adopts: a kind of thomel strengthens the die mould carbon tube, and the raw material of making said thomel enhancing die mould carbon tube is following component by mass percent: 12-18% thomel, 18-22% resol, 60-70% Graphite Powder 99.
As optimization, the length of said thomel is 4.5-5.5mm, and fiber length helps the mechanical property of pressed pipe, but outward appearance is more coarse, and fiber is short, and mechanical property promotes not obvious.
Beneficial effect: die mould carbon tube of the present invention adds thomel in making processes, has improved die mould carbon tube mechanical property.
Embodiment
Below in conjunction with specific embodiment the present invention is described further:
Embodiment 1
The raw material of making thomel enhancing die mould carbon tube is following mass percent component: 12% thomel, 18% resol, 70% Graphite Powder 99, the length of said thomel are 4.5mm.
Embodiment 2
The raw material of making thomel enhancing die mould carbon tube is following mass percent component: 15% thomel, 20% resol, 65% Graphite Powder 99, the length of said thomel are 5mm.
Embodiment 3
The raw material of making thomel enhancing die mould carbon tube is following mass percent component: 18% thomel, 22% resol, 60% Graphite Powder 99, the length of said thomel are 5.5mm.
Thomel behind the foregoing description interpolation fiber strengthens the mode of employing of die mould carbon tube and the identical manufacturing of original technology, and it is following that the thomel after completing strengthens die mould carbon tube mechanical property: the about 35MPa of tensile strength, bending strength
About 400 Mpa.
