Wet-molded felt is a material formed by compounding carbon fiber and resin through a wet process, which has the following significant advantages:

I. Main performance advantages

Corrosion resistance

The surface of wet-molded felt forms a uniform resin coating, which can effectively resist the erosion of corrosive media such as acids, alkalis, and salts, and is suitable for special environments such as chemical industry and ocean.

High temperature resistance

The high temperature resistant resin system is adopted, and the working temperature range is wide, which can meet the needs of aerospace, high temperature equipment and other fields.

Insulation and sound insulation effect

The porous structure design reduces heat conduction, and the material itself blocks sound propagation, which is suitable for building sound insulation and insulation systems.

Lightweight

Compared with traditional composite materials, wet-molded felt has a lower density (80-100kg/m³ for dry method and 100-130kg/m³ for wet method), which reduces the structural load.

II. Process and performance optimization
Dimensional stability
The wet process ensures uniform fiber distribution, high product dimensional stability, and reduces deformation caused by environmental changes.
Surface flatness
The surface finish is improved through the stitching process, which is convenient for subsequent processing and decoration, especially suitable for scenes with high surface quality requirements such as kitchenware and building templates.
Customizability
The resin formula and fiber content can be adjusted to meet different performance requirements, such as enhancing acid and alkali resistance or high temperature resistance.
Wet-molded graphite felt is a composite material prepared by wet impregnation. Its advantages and disadvantages are as follows:
1. Advantages
Strong corrosion resistance
During the wet molding process, graphite fibers are combined with the matrix material through chemical bonding to form a dense microstructure, which significantly improves corrosion resistance and is suitable for corrosive environments such as chemical and environmental protection.
Flexible process
Graphite felts with different properties can be customized by adjusting the wet impregnation liquid formula and process parameters to meet diverse needs.
Low equipment investment
Compared with dry molding, wet equipment is simple, suitable for small and medium-sized production, and reduces initial investment costs.
2. Disadvantages
High cost
Wet production requires the use of chemical solvents and special equipment, and the subsequent processing is complicated, resulting in an overall cost higher than the dry process.
Long drying time
It takes a long time to dry, usually several days to a week, which affects production efficiency.
Low product purity
Impurities may be introduced during the wet impregnation process, and the surface treatment process may affect the density of the felt layer, resulting in a purity slightly inferior to that of dry products.
Size limitation
Due to the limitations of equipment volume and operating space, wet molding is difficult to produce oversized graphite felt.
