Building Stronger Ships: Application Cases And Technical Advantages of Yuniu Chopped Glass Fiber Mat

What is chopped strand mat?

Chopped strand mat is a nonwoven fabric made of glass fiber after cutting and dispersing. It is mainly made of E-glass (electronic grade glass fiber) and has excellent mechanical properties and chemical stability. This material is widely used in composite materials, especially in applications that require enhanced structural strength and durability.

Why is chopped strand mat needed?

1. Enhanced structural strength: Chopped strand mat can significantly improve the structural strength of the hull, especially in the manufacturing process of composite hulls. By enhancing the rigidity and compressive resistance of the hull, chopped strand mat ensures the safety and reliability of the ship in various environments.

2. Lightweight: The lightweight characteristics of chopped strand mat help to improve the speed and fuel efficiency of the ship, making it more advantageous in the highly competitive shipping market.

3. Corrosion resistance: In the marine environment, chopped strand mat can resist the erosion of seawater and other corrosive media, extending the service life of the ship.

Application cases of chopped strand mat

1. Shipbuilding:

- Case 1: A large shipbuilding company used Yuniu fiberglass chopped strand mat to build a luxury yacht. By using chopped strands of felt in the hull structure, the structural strength of the yacht is significantly improved, while maintaining a lightweight design and improving fuel efficiency.

- Case 2: A fishing boat manufacturing company uses chopped strands of felt to strengthen the hull structure, successfully solving the problem of traditional materials being easily corroded in the marine environment and extending the service life of the fishing boat.

2. Ship repair:

- Case 1: A commercial cargo ship had hull cracks during long-term use. After repairing it with Yuniu fiberglass chopped strands of felt, the cracks were effectively filled, the hull structure was significantly enhanced, and normal operation was restored.

- Case 2 : A cruise ship was damaged in an accident. By using chopped strands of felt for repair, not only the integrity of the hull was restored, but also the corrosion resistance of the hull was improved, ensuring the safe operation of the cruise ship.

3. Actual projects:

- Project 1: In a naval ship project, chopped strands of felt were used to strengthen the deck and bulkhead of the ship, significantly improving the impact resistance and corrosion resistance of the ship, and ensuring the reliability and safety of the ship in complex environments.

- Project 2: A yacht club uses chopped strand mat to regularly maintain and repair its members' yachts, significantly improving the service life and performance of the yachts and winning high praise from members.

Technical advantages of chopped strand mat

1. High alkali resistance: After immersion in an alkaline solution with a pH value of 12 for 72 hours, the strength loss of the chopped strand mat does not exceed 5%, showing excellent alkali resistance.

2. High strength: After testing, the tensile strength of the chopped strand mat reaches or exceeds 800 MPa, and the elongation at break can reach 3%, ensuring reliability and stability when subjected to stress.

3. Excellent resin permeability: The chopped strand mat combines well with the resin to form a strong composite layer and improve the overall performance of the material.

4. Wear and corrosion resistance: After immersion in simulated seawater conditions for 30 days, the strength of the chopped strand mat decreases by no more than 3%, showing excellent wear and corrosion resistance.

Installation and use of chopped strand mat

1. Preparation:

-Material selection: Select high-quality E-glass chopped strand mat to ensure the performance and reliability of the material.

-Tool preparation: Prepare necessary construction tools, such as scissors, brushes, rollers, etc.

2. Construction steps:

-Surface treatment: Clean and polish the surface to be constructed to ensure that the surface is clean and flat.

Laying chopped strand mat: Lay the chopped strand mat evenly in the area to be reinforced to ensure that there are no bubbles and wrinkles.

-Resin coating: Apply resin evenly on the chopped strand mat to ensure that the resin fully penetrates into the chopped strand mat.

-Curing treatment: Treat according to the curing requirements of the resin to ensure that the composite material layer is completely cured.

3. Precautions:

Environmental conditions: Choose appropriate environmental conditions during construction to avoid adverse factors such as high temperature and high humidity.

Safety measures: Pay attention to personal protection during construction and wear protective equipment such as masks and gloves.

Industry standards and regulations

1. International standards:

ISO standards: The International Organization for Standardization (ISO) has developed a number of standards on chopped strand mats in shipbuilding, such as ISO 12215-3 "Ships and offshore technology - Marine composite materials - Part 3: Structural design of glass fiber reinforced plastic (GRP) hulls".

2. **National standards:

Chinese standards: China Classification Society (CCS) has developed relevant standards such as "Rules for Classification and Construction of Seagoing Steel Ships", which put forward specific requirements for chopped strand mats used in shipbuilding.

American standards: The American Bureau of Shipping (ABS) has developed relevant standards such as "Rules for the Construction of Steel Ships", which put forward clear requirements for the performance and use of chopped strand mats.

Conclusion

Chopped strand mats play an important role in shipbuilding and repair. Their high alkali resistance, high strength, excellent resin permeability and wear resistance make them an ideal choice for improving ship performance and safety. By using chopped strand mats from Yuniu Fiberglass, you can significantly improve the structural strength and durability of the hull and extend the service life of the ship.
