1. Carbon Fiber Sheet Overview
Carbon fiber sheets, also known as carbon fiber plates, are pre-cured composite panels made from multiple layers of carbon fiber fabric impregnated with epoxy resin and cured under high pressure and temperature. The resulting product offers exceptional stiffness, strength, and dimensional stability while maintaining an ultra-lightweight profile.
At Impact Materials, we supply carbon fiber sheets in thicknesses ranging from 0.5mm to 50mm, with various surface finishes including glossy, matte, and textured options. Our sheets are available in plain weave, twill weave, and unidirectional patterns, allowing you to select the most suitable configuration for your specific application requirements.
The manufacturing process involves precision layup of carbon fiber prepreg layers, followed by autoclave or compression molding to ensure consistent quality, void-free construction, and superior mechanical properties. Every batch includes Material Test Certificate (MTC) with full traceability to raw material lots.
2. Carbon Fiber Sheet Specifications & Grades
Selecting the appropriate carbon fiber sheet specifications is essential for achieving optimal performance in your application. Impact Materials supplies sheets in three primary grades, each optimized for different performance and cost requirements.
T700 carbon fiber sheets represent the most suitable balance of performance and cost for most structural applications. With 39% higher tensile strength than T300 (4,900 MPa vs 3,530 MPa), T700 sheets are the industry standard for aerospace, automotive, and high-performance industrial applications requiring ISO 9001 certification and full material traceability.
3. Carbon Fiber Tube Overview
Carbon fiber tubes are cylindrical structural components manufactured through pultrusion or roll-wrapping processes. These tubes offer exceptional bending stiffness and compressive strength while maintaining minimal weight—making them ideal for applications requiring high rigidity and low mass.
At Impact Materials, we supply carbon fiber tubes in diameters ranging from 3mm to 400mm, with wall thicknesses from 0.5mm to 20mm. Our tubes are available in round, square, rectangular, and elliptical profiles to match diverse structural requirements. Both pultruded (cost-effective, high volume) and roll-wrapped (superior mechanical properties, custom layups) options are available.
The manufacturing process involves precision winding of carbon fiber prepreg layers at specific angles (typically 0°, 90°, and ±45°) to optimize mechanical properties for the intended load conditions. Every tube undergoes rigorous quality control including dimensional inspection, visual examination, and mechanical testing when required.
4. Carbon Fiber Tube Specifications & Profiles
Selecting the appropriate carbon fiber tube specifications is crucial for achieving most suitable structural performance. Impact Materials supplies tubes in various profiles, grades, and manufacturing methods to match your application requirements.
For applications requiring maximum bending stiffness, roll-wrapped tubes with optimized fiber orientation (higher percentage of 0° fibers) offer superior performance compared to pultruded tubes. However, pultruded tubes provide excellent cost-effectiveness for high-volume production where standard mechanical properties are sufficient. Our technical team can help you select the perfect manufacturing method based on your specific requirements.

7. Frequently Asked Questions (FAQ)
Q: What is the difference between carbon fiber sheets and plates?
A: The terms are often used interchangeably. Generally, “sheets” refer to thinner materials (0.5-5mm), while “plates” refer to thicker sections (5-50mm). At Impact Materials, we use “sheet” for all thicknesses to maintain consistency across our product catalog.
Q: What is the difference between pultruded and roll-wrapped carbon fiber tubes?
A: Pultruded tubes are cost-effective with consistent properties, ideal for high-volume production. Roll-wrapped tubes offer superior mechanical properties with customizable fiber orientation, perfect for high-performance applications requiring optimized stiffness and strength.
Q: Can you cut carbon fiber sheets and tubes to custom sizes?
A: Yes! Impact Materials offers custom cutting services for sheets (any size up to 1000×1000mm) and tubes (any length up to 6000mm). We also provide CNC machining, drilling, and edge finishing services. Contact our technical team for a quote.
Q: What adhesives work best for bonding carbon fiber?
A: Epoxy adhesives provide the strongest bonds for carbon fiber-to-carbon fiber joints. For carbon fiber-to-metal bonds, use structural acrylics or modified epoxy. Surface preparation (sanding with 80-120 grit, cleaning with acetone) is critical for optimal bond strength.
Q: Do you provide Material Test Certificates (MTC)?
A: Yes! Every batch of carbon fiber sheets and tubes from Impact Materials includes a Material Test Certificate (MTC) with full traceability to raw material lots. MTC includes tensile strength, modulus, density, and fiber content test results per ISO 9001 requirements.
