CARBON Fibre rods pultruded round (DPP™ / R&G)

Pultruded CFRP rods made from high-strength carbon fibers and epoxy resin are ideally suited for lightweight, high-load structural applications with loads acting primarily in the longitudinal direction. They are manufactured using a continuous pultrusion process with 3K high-tensile carbon fibers (e.g. Torayca® T300/T700 or equivalent) embedded in a thermosetting epoxy resin matrix.

Due to the pultrusion manufacturing process, the fibers are aligned unidirectionally along the rod axis. This results in profiles with exceptionally high tensile strength and stiffness in fiber direction, a high fiber volume content and very low void content.

The CFRP rods are available in two quality grades, differing in dimensional accuracy, surface finish, manufacturing precision and price.

DPP™ (Premium Grade)

The premium-grade “DPP™” rods are manufactured in the Netherlands and feature outstanding dimensional accuracy, very tight tolerances and excellent straightness. A high fibre volume content of 60-65 Vol.-% combined with an extremely low void content provides optimized mechanical properties.

DPP™ rods are particularly suitable for small diameters and highly precise or tolerance-critical applications. Due to the manufacturing process, the surface is slightly rougher.

Standard (R&G)

The “R&G” version is an economical alternative for general technical applications. It offers good to very good industrial tolerances, a smoother surface finish and a high fibre content of approx. 63 Vol.-%.

This version is especially suitable for applications with lower requirements regarding tight tolerances and maximum precision.

Typical Technical Properties

(depending on grade)

Fiber type: HT carbon fiber (Torayca® T300/T700 or equivalent)
Fiber orientation: unidirectional
Matrix system: Epoxy resin/vinylester resin
Density: approx. 1.78 g/cm³
Heat distortion temperature: approx. 120 °C
Tensile strength: > 3 GPa
Tensile modulus: > 200 GPa
Interlaminar shear strength (ILSS): approx. 100 MPa
Very high strength and stiffness in fiber direction

Tolerances

DPP™ rods feature particularly tight tolerances and excellent straightness. The standard version offers good industrial tolerances with slightly larger deviations.

Straightness deviation is typically limited to a maximum of 1 mm/m.

Processing Instructions

These rods are especially suitable for structural applications with loads acting in the longitudinal direction.

Internal release agents used during the pultrusion process may migrate to the surface. For optimum bonding performance, careful surface preparation is therefore recommended:

Sand bonding surfaces using 220 grit abrasive paper
Thoroughly remove sanding dust before bonding

Recommended adhesives:

Epoxy resin adhesives
Cyanoacrylate adhesives (instant adhesives)
