FAQ

1. What resin systems are used in fiberglass prepreg?

Common resin systems include:

• Epoxy resin (most common)

• Flame-retardant epoxy systems

• High-temperature resin systems

• Toughened resin systems for improved impact resistance

The resin system can be selected based on application requirements.

2. What applications is prepreg fiberglass used for?

It is widely used in:

• Automotive interior and structural components

• Electrical insulation parts

• Wind energy and industrial equipment

• Marine and shipbuilding applications

• Consumer and sporting goods

3. How is prepreg fiberglass processed?

Prepreg fiberglass is typically processed using:

• Hot press molding

• Autoclave curing

• Vacuum bagging (in some applications)

Final performance depends on curing temperature, pressure, and cycle time.

4. What storage conditions are required?

Prepreg fiberglass must be stored under controlled conditions:

• Refrigerated storage (commonly -10°C or below)

• Sealed packaging to prevent moisture and contamination

• Limited room-temperature exposure before curing

5. Can prepreg fiberglass be customized?

Yes, customization is available for:

• Fiber type (E-glass, S-glass, etc.)

• Resin system and resin content

• Fabric structure (woven or unidirectional)

• Width, thickness, and roll length

• Performance requirements such as flame retardancy or high temperature resistance

6. Do you offer free samples?

Yes, we provide free samples for testing and evaluation. In most cases, customers only need to cover the shipping cost before bulk orders.
