Over the past century of industrial development, metal materials have been the core cornerstone of manufacturing. From steel to aluminum alloys, metals have underpinned the vigorous growth of sectors such as transportation, construction, energy, and machinery. However, as the global manufacturing industry enters a new phase defined by low-carbonization, lightweighting, and high performance, metals are increasingly revealing limitations in certain applications—issues such as high weight, long processing cycles, limited corrosion resistance, and difficult recyclability are becoming more prominent.

Against this backdrop, composite materials are regarded as the "core materials of next-generation industrial manufacturing." Among them, Continuous Fiber Reinforced Thermoplastic (CFRT) laminates, with advantages including high specific strength, rapid formability, and recyclability, are emerging as a key force in replacing metals. They are not merely a new type of material, but also a critical driver for the transformation of industrial manufacturing models from the metal era to the composite era.

I. The Historical Status and Current Bottlenecks of Metal Materials

1. The Glorious Era of Metal Materials

During the development of the steam engine, internal combustion engine, and aerospace industries, steel and aluminum alloys dominated absolutely due to their high strength, good processability, and mature supply chains. Steel accounts for over 60% of the total weight of automobiles; most aircraft fuselages are made of aluminum alloys; ships, bridges, and rail vehicles also rely heavily on steel.

2. Emerging Limitations

Weight Issue: The high density of metals limits the ultimate potential of lightweight design.
Insufficient Corrosion Resistance: Both aluminum alloys and steel require additional coatings or anti-corrosion treatments.
Long Manufacturing Cycles: Especially for large or complex structural components, metal part manufacturing involves multiple processes.
Recycling Pressure: While metal recycling is feasible, it consumes high energy and generates significant carbon emissions.

These bottlenecks conflict with the modern industrial demands for efficiency, low carbon, and sustainability, creating conditions for the rise of composite materials.

II. Revolutionary Characteristics of CFRT Thermoplastic Laminates

1. High Specific Strength and High Specific Stiffness

The specific strength of CFRT can reach 5–7 times that of steel, and its specific stiffness is significantly superior to aluminum alloys. Under the same load-bearing capacity, its weight can be reduced by 40%–60%.

2. Thermoplasticity and Rapid Forming

Unlike thermosetting composites, which require long curing times, CFRT laminates can be rapidly formed after being heated to the melting temperature. The forming cycle can be as short as 1–3 minutes, greatly improving production efficiency.

3. Corrosion Resistance and Weather Resistance

The matrix of CFRT laminates is high-performance thermoplastic resin, which is resistant to chemical corrosion and UV aging, making it suitable for extreme environments such as marine, high-humidity, and high-salt conditions.

4. Recyclability and Secondary Processing

At the end of the material’s lifecycle, CFRT can be reprocessed into new parts or laminates through heating, reducing waste and environmental pressure.

III. Strategic Significance of the Shift from the Metal Era to the Composite Era

1. Structural Weight Reduction and Energy Efficiency Improvement

In the transportation sector, structural weight reduction directly translates to improved fuel economy and extended EV range. In the aviation sector, reducing weight by 1 kg can save thousands of dollars in fuel costs over an aircraft’s entire lifecycle. The application of CFRT can significantly reduce the overall weight of equipment, leading to a leap in energy efficiency.

2. Innovation in Manufacturing Models

The rapid forming and integration capabilities of CFRT enable the reduction in the number of parts and simplification of assembly processes. For example, a complex metal structure may require 10 parts welded together, while CFRT can be thermoformed in one step, drastically reducing the need for fasteners and welding.

3. Supply Chain Upgrading

Metal processing relies on traditional chains such as metallurgy, forging, and machining, while CFRT depends on polymer production, fiber manufacturing, and composite forming technologies. This means the manufacturing industry will upgrade toward polymer chemical engineering and advanced material processing, spawning new industrial clusters.

4. Carbon Emission and Environmental Strategy

Metal production (especially steel) is a major global source of carbon emissions. CFRT laminates generate low carbon emissions during production, save energy during use, and can be reused during recycling, aligning with the "dual carbon" strategy (carbon peaking and carbon neutrality).

IV. Metal Replacement Cases in Application Fields

1. Automotive Manufacturing

Exterior Body Panels: Replacing traditional steel plates with CFRT laminates reduces weight by 50% while providing better dent resistance.
Chassis Components: Replacing aluminum alloys with CFRT for battery trays and underbody shields achieves both corrosion resistance and weight reduction.

2. Aerospace

Interior Components: CFRT can replace aluminum alloy cabin panels, achieving both lightweighting and flame retardancy.
UAV Frames: The high stiffness and impact resistance of CFRT make UAVs more durable.

3. Marine and Offshore Engineering Equipment

CFRT replaces steel in decks, hull sides, and other components, not only reducing weight but also eliminating the high costs of long-term anti-corrosion maintenance.

4. Industrial Machinery

Replacing metals with CFRT for the housings and protective covers of large machinery reduces transportation and installation difficulties while improving weather resistance.

V. Industrial Chain and Technology Ecosystem

1. Raw Material Segment

CFRT is based on the combination of fibers (carbon fiber, glass fiber, aramid fiber, etc.) and thermoplastic matrices (e.g., PA, PPS, PEEK).

2. Forming and Processing Segment

Technologies such as automated tape laying (ATL), hot press forming, and compression molding are constantly maturing, enabling large-scale production of CFRT.

3. Downstream Integration

In the future, manufacturing enterprises can achieve "one-step production" from CAD design to finished product forming through design optimization and material innovation.

VI. Future Development Trends

1. Material and Process Integration

Integrating fiber laying, matrix impregnation, and thermoforming into a single production line to further shorten the production cycle.

2. Intelligent Manufacturing and Digital Twins

Using sensors and simulation technologies to realize real-time monitoring and predictive maintenance of CFRT structures.

3. Integration with Green Energy

CFRT laminates can be combined with photovoltaic systems, energy storage, and electric drive systems to manufacture lightweight structures integrated with energy functions.

Conclusion

CFRT thermoplastic laminates are more than just a metal replacement material—they represent a major shift in industrial manufacturing concepts: moving from large-scale metal-dependent manufacturing to lightweight, intelligent, and low-carbon manufacturing based on high-performance composites. This transformation will not only improve product performance and economic efficiency but also drive the entire industrial chain toward higher value-added upgrading.

It is foreseeable that with the in-depth transformation of the global manufacturing industry under the "dual carbon" goals, CFRT will become the strategic core for replacing some metal materials. The manufacturing industry of the future may be built on composite materials, ushering in a brand-new era of development.
