Advantages of composites:

    1. Lightweight: composites offer excellent strength-to-weight ratios.
    2. Durability: They resist corrosion and wear and can handle harsh environments.
    3. Versatility: the properties of composites can be adapted to the needs of the application.
    4. Low long-term cost of ownership: Lower maintenance requirements and long life reduce life cycle costs.
    5. Design Flexibility: Composites are structurally designable, allowing materials to be engineered with specific properties as needed.

How to choose the right material?

    1. Consider the application requirements: What is the purpose of the part? Is strength or lightweighting required?
    2. Evaluate environmental factors: Will the material be exposed to moisture, chemicals or high temperatures?
    3. Evaluate mechanical properties: Select a material based on the strength, stiffness and durability required.
    4. Balancing cost and performance: Find a balance between material performance and cost-effectiveness.
    5. Recyclability: For environmentally conscious industries, prioritize recyclable thermoplastic composites.

Which industries benefit from composites?

Aerospace

Carbon fiber composites are widely used in aircraft fuselage and wing structures due to their high strength and light weight. This not only reduces the weight of the aircraft, improves fuel efficiency and range, but also enhances the overall performance and safety of the aircraft.

Automotive

Fiberglass and carbon fiber composites are commonly used in automotive bodies, hoods and interior components. These materials reduce vehicle weight, improve fuel economy and handling, and increase safety in a crash.

Motorcycles

Carbon fiber and fiberglass composites are used in a large number of motorcycle frames, exhaust systems and exterior panels. These materials make motorcycles lighter, increase speed and fuel efficiency, while enhancing vehicle rigidity and impact resistance, providing riders with a better handling experience.

Medical

Carbon fiber and polymer matrix composites are used in the manufacture of medical devices such as prosthetics, surgical instruments and stents. These materials are biocompatible, lightweight and strong, improving patient comfort and reducing the weight of devices while increasing their durability and precision.

Construction

Fiber Reinforced Plastics (FRP) are commonly used in bridge reinforcement, facade and roof design. the corrosion resistance and high strength of FRP make buildings more durable in harsh environments, reducing maintenance costs and improving safety.

Marine

Fiberglass composites are widely used in the manufacture of boat hulls, decks and masts. The materials are corrosion-resistant, lightweight and resistant to salt water and high humidity in the marine environment, extending the life of the vessel while improving sailing efficiency.

FAQ

Composites are engineered materials made from a combination of two or more different materials designed to achieve superior performance.

Composites are typically composed of a matrix (which acts as a bond) and reinforcements (which provide strength and rigidity). Common matrices include polymers, metals and ceramics, while reinforcements are usually carbon or glass fibers, for example.

Materials are selected based on the strength, weight, and environmental requirements of the part in conjunction with budgetary considerations.

No. The use of specialized equipment such as CNC machines and waterjet cutters ensures minimal material damage.

It depends on the complexity and processing method. CNC machining and laser cutting are faster, while molding has a longer cycle time.

Composites are lighter, corrosion-resistant, and can be customized to meet specific needs, while metal offers greater structural strength.
