3K, Plain Weave Carbon Fiber Fabric

For Lightweight, High-Strength, Aerodynamic Parts

For lightweight aerodynamic parts, this plain weave carbon fiber features a 3k tow (3000 filliments per fiber) and is a commonly selected fabric style, delivering uniform strength in both horizontal and vertical directions.

It wets out quickly and handles easily. Only three layers are typically necessary to produce non-structural pieces.Available in 50" or 60", #530 and #1530 boasts an ultimate tensile strength of at least 610 KSI—most competitors offer only around 500 KSI

3K, Plain Weave Carbon Fiber Fabric Features

• 12.5 x 12.5 plain weave offers a tight weave, which is less likely to fray
• Wets out quickly
• Unmatched strength to weight ratio
• High Modulus for superior rigidity
• Fatigue resistance for durable strength

3K, Plain Weave Carbon Fiber Fabric Tips

• Ideal for lightweight parts used in aerospace applications.
• To maximize strength properties, use with an epoxy, like our System 2000 Epoxy Resin (#2000).
• For added conformability, lay up the fabric at a 45-degree bias inside molds.
• This fabric is available in thin strip tapes for unique shapes or wrapping applications.

What is 3K Plain Weave Carbon Fiber Fabric?

The 3K Plain Weave Carbon Fiber Fabric (#530) from Fibre Glast is a commonly selected fabric style for lightweight, high-strength aerodynamic parts.

This fabric features 3K carbon tow (3,000 filaments per fiber) woven in a tight 12.5 x 12.5 plain weave pattern, weighing 5.4-5.9 oz/sq yd.

Available in both 50-inch (#530) and 60-inch (#1530) widths, the #530 boasts an ultimate tensile strength of 610-635 KSI — most competitors offer only around 500 KSI. The plain weave construction delivers uniform strength in both horizontal and vertical directions.

It wets out quickly and handles easily, with only three layers typically necessary to produce non-structural pieces.

Why Choose Plain Weave Over Twill Weave Carbon Fiber?

Plain weave carbon fiber provides uniform strength in both horizontal and vertical directions, making it ideal for applications requiring balanced bidirectional properties.

The tight 12.5 x 12.5 weave construction is less likely to fray than looser weave patterns, providing cleaner edges and easier handling during fabrication.

While twill weave offers greater conformability for complex curves and is slightly stronger than plain weave, plain weave provides superior dimensional stability and holds together well when cut.

Plain weave is the preferred choice when consistent handling and clean fabrication are more important than maximum drapability over compound contours.

What Are the Best Applications for #530 Plain Weave Carbon?

The #530 is ideal for lightweight parts used in aerospace applications where uniform bidirectional strength is required.

The fabric wets out quickly and handles easily during fabrication. This fabric is also available in thin strip tapes for unique shapes or wrapping applications.

How Should #530 Plain Weave Carbon Be Used for Best Results?

To maximize strength properties, use with an epoxy resin such as Fibre Glast System 2000 Epoxy (#2000).

For added conformability on curved surfaces, lay up the fabric at a 45-degree bias inside molds. 

The tight plain weave naturally reduces fraying at cut edges compared to twill weaves, making it easier to handle during layup.

Available in 1-yard (#530-A), 3-yard (#530-B), and 5-yard (#530-C) prepacks, as well as continuous cut-to-length yardage for orders of 10 yards or more.

A 60-inch wide version is also available (#1530). Quantity discounts continue to deepen as yardage increases for any single cut of fabric.

Fibre Glast is committed to ensuring that every roll of fabric is First Quality and manufactured to the highest standards, delivering consistent properties and handling characteristics every time you order.

Rolled fabrics ship in a long (45", 53", or 62") box. Click below on the "What to expect when you order Fabric" video to see how rolled fabrics are cut and shipped each time you order.

3K, Plain Weave Carbon Fiber Fabric This fabric is sold by the linear yard, either as a prepackaged quantity or by continuous yardage. Prepacks This fabric is available in pre-cut lengths that measure one yard (#530-A, roll), three yards (#530-B, roll), and five yards (#530-C, roll). Each is packaged and sold separately. For your convenience, these "prepacks" can be purchased in any combination. However, if the length for any one fabric totals 10 yards or more, we suggest you purchase it in continuous, "cut to length" yardage. Continuous, "Cut to Length" Yardage If you know in advance that you intend to purchase 10 yards or more of any one fabric, it should be ordered in continuous, "cut to length" yardage. In this case, fabric will be cut once according to the total yardage ordered, and customers receive a price-per-yard discount as compared to prepacks. Quantity discounts continue to deepen as the yardage increases for any one cut of one fabric.
