• Unidirectional (UD): Fibers aligned in a single direction, providing maximum strength and stiffness along that axis.

• Bidirectional Weaves: Includes plain weave and twill weave patterns, offering balanced mechanical properties and enhanced aesthetics.

• Multidirectional Laminates: Layers oriented at various angles (0°, 45°, 90°) for tailored mechanical behavior.

4. Thickness Range

• Typically from 0.5 mm up to 20 mm or more.

• Custom thicknesses are achievable by varying the number of layers and resin content.

5. Density

• Usually ranges from 1.5 to 1.6 g/cm³.

• Significantly lighter than metals such as steel (7.85 g/cm³) or aluminum (2.7 g/cm³).

6. Mechanical Properties

7. Thermal Properties

• Thermal Conductivity: Moderate, highly anisotropic; better along fiber direction.

• Max Service Temperature: Typically 120°C for epoxy; specialty resins allow up to 250°C+.

• Coefficient of Thermal Expansion (CTE): Near zero or negative along fiber axis; very low overall.

8. Electrical Properties

• Carbon fiber is conductive; plate material exhibits semi-conductive behavior.

• Important in applications requiring grounding or electromagnetic shielding.
