Carbon fiber fabric reinforced PPS prepreg production process and equipment

Abstract

The invention discloses a carbon fiber fabric reinforced PPS prepreg production process and equipment, relates to the technical field of carbon fiber fabric reinforced PPS prepreg production, and is mainly used for solving the problem that domestic carbon fiber fabric reinforced PPS prepreg does not have industrial production conditions at present. The carbon fiber fabric reinforced PPS prepreg production process comprises the following steps of 1, unwinding and tensioning; 2, removing a sizing agent; 3, gluing on the double sides; 4, extruding and impregnating; 5, cooling; 6, online detecting; and 7, winding. The equipment structurally comprises an unwinding device, a front-section guide roller, a first drying oven, a gluing roller set, a second drying oven, a heat insulation cavity, a cooling cavity, an on-line weighing instrument, a traction roller set and a winding device. According to the carbon fiber fabric reinforced PPS prepreg production process and the equipment provided by the invention, the industrial production of the carbon fiber fabric reinforced PPS prepreg can be completed by utilizing the process and the equipment.

Description

technical field [0001] The invention relates to the technical field of carbon fiber fabric reinforced PPS prepreg production technology, in particular to a carbon fiber fabric reinforced PPS prepreg production process and equipment. Background technique [0002] Because carbon fiber fabric reinforced PPS prepreg not only has good insulation and flame retardant properties, but also has high tensile strength and modulus, high flexural strength and modulus, and excellent high temperature resistance. It is used in aviation, rail transit, automobiles, etc. More and more fields have been promoted and applied. [0003] However, due to some reasons: 1. The carbon fiber fabric reinforced PPS prepreg is difficult to soak due to the fiber overlap of the carbon fiber fabric. At the same time, since the sizing agent on the surface of the carbon fiber fabric does not match the PPS, it needs to be removed in advance, but the surface of the carbon fiber after removing the sizing agent is i...

Problems solved by technology

[0003] However, due to some reasons: 1. The carbon fiber fabric reinforced PPS prepreg is difficult to soak due to the fiber overlap of the carbon fiber fabric

At the same time, because the sizing agent on the surface of the carbon fiber fabric does not match the PPS, it needs to be removed in advance, but the surface of the carbon fiber after removing the sizing agent is inert, which makes it more difficult for the PPS resin to infiltrate the fiber cloth

2. The final infiltration molding of prepreg depends on the extrusion of steel rollers. During the process of rolling molten resin, since the pressure rollers will inevitably bond PPS resin, the bonding of resin is uneven and irregular. It will seriously affect the production efficiency and product quality, and cannot be mass-produced

As a result, China can only provide some laboratory-level samples at present, and the domestic demand for carbon fiber fabric reinforced PPS prepregs is completely dependent on imports.
