Carbon Fiber Towpreg

 

 

High Gain Industrial Carbon Fiber Towpreg has a proprietary thermosetting resin system and can be stored at room temperature. It can be used with many types of filament winding machines and new processes like automatic tape placement directly.

Epoxy Resin Content: Resin content and fiber can be adjusted according to product and manufacturing processes, generally it would be around 32%

No release film is needed and the resin content is rather accurate during the production. The working environment is largely improved and the mechanical properties of the final products are upgraded while the number of defects is reduced. The weight can be controlled effectively.

 

 

Resin System: HG-518 (Medium Temperature Curing) Resin

Carbon Fiber: Toray T700SC-50C or equivalent

HG-518 Epoxy Resin is designed for filament winding. It is suitable for carbon fiber and glass fiber and relatively have a longer working time. It has good strength, good impact resistance and is suitable for pressure vessel filament winding process.

Points to Note When Using Towpreg

1. Pregin material consistency: One of the crucial points to consider while using Carbon Fiber Towpreg production is the consistency of the material. The tow should be carefully selected to ensure uniformity in resin absorption.

 

2. Proper storage: Be stored correctly to prevent UV radiation exposure, and changes in temperature to maintain its properties and quality during production.

 

3. Resin selection: The resin used in producing pregin should be selected carefully to match the cure cycle of the tow. It should also be compatible with the manufacturing process, and other manufacturing materials.

 

4. Proper handling: Adequate care should be taken while handling carbon fiber tow as it is fragile and can be easily damaged. Verifying the handling capabilities of the equipment used in manufacturing is necessary.

 

5. Quality control: Quality control measures should be implemented at every stage of the production process to ensure that production standards are met.

 

6. Testing: The finished product should be tested to ensure that the properties of the material meet the desired specifications. Testing can help to identify any issues early and improve the quality of the final product.

 

7. Proper labeling:Should be appropriately labeled with critical information such as manufacturing date, batch code or roll number for easy identification, and traceability.

 

8. Safety measures: Safety measures must be put in place to ensure that all personnel working with carbon fiber tow are protected from harm. This includes providing personal protective equipment and training on handling and storage procedures.
