Abstract

The invention discloses a manufacturing process of a degradable carbon felt prepreg, the degradable carbon felt prepreg and a process for manufacturing a composite automotive hood inner plate by usingthe carbon felt prepreg, and relates to the technical field of automotive covering parts. The process comprises the following steps of step I, adding a RAF-901 resin A component and a B component thickening agent into a series mixer for stirring, and thus obtaining an epoxy resin paste. The carbon felt prepreg obtained by the manufacturing process of the carbon felt prepreg has uniform appearanceand a good demoulding performance, is non-stick, and can meet the low VOC environmental protection requirements of automotive part materials. The carbon felt prepreg which can be cured quickly is used as a raw material to be applied to the process of the composite automotive hood inner plate, the production efficiency of finished products is high, the cycle is short, the cost is low, the qualityis stable, and the automobile lightweight, energy conservation environmental protection are realized.

Description

technical field

[0001] The invention relates to the technical field of automobile covers, in particular to a process for manufacturing a degradable carbon felt prepreg, a degradable carbon felt prepreg, and a composite automobile hood inner panel made of a carbon felt prepreg craft. Background technique

[0002] Recyclable fiber-reinforced thermosetting materials, referred to as RFRT, with the development of composite material automated mass production technology, the cost of composite material manufacturing has been greatly reduced, and people have a better understanding of the weight-reducing effect of composite materials. The application of composite materials in automobiles is also increasing. Great progress has been made. Most of the existing automotive composite hoods are steel plates, aluminum plates or continuous carbon fiber composite materials. Among the quality of steel plates and aluminum plates, continuous carbon fibers can greatly achieve the goal of weight red...

Examples

Embodiment 1

[0027] Such as Figure 1 to Figure 3 Shown, a kind of degradable carbon felt prepreg manufacturing process is characterized in that, comprises the steps:

[0028] Step 1. Add component A of RAF-901 resin to the serial mixer at 900-1200 rpm;

[0029] Step 2: Add component B thickener into the serial mixer and stir evenly to obtain epoxy resin paste;

[0030] Step 3: Clean up the RFRT sheet material machine, prepare the PP film, add the mixed epoxy resin paste to the upper and lower glue tanks, turn on the equipment, apply the epoxy resin paste to the inner surface of the upper and lower PP film, and then Composite with chopped carbon fiber mat;

[0031] Step 4: pressurize again, impregnate the carbon fiber felt with resin, and then wind up the resin-impregnated carbon felt with a 6-10-inch inflatable shaft;
