Reinforcing tapes: purpose and product-form selection

The tape describes the narrow shape of the reinforcing material, but does not guarantee the specific structure or availability of the position. The page helps you define requirements and navigate to approved fabrics or carbon raw materials.

Why choose a narrow format

The tape format can be useful for localized areas, long elements, winding, path reinforcement, or reducing waste in narrow cuts. The specific function depends on the reinforcement structure and process.

One name may include woven strip, unidirectional material, formed rope strip, or other semi-finished product. Therefore, width by itself does not create a technical brief.

If the desired tape is to be cut from a wide fabric, check edge stability, orientation, waste and markability. This route is not always equivalent to the factory tape position.

Trajectory, joints and overlaps

For local reinforcement, it is important to describe where the tape begins and ends, how the direction changes, and what happens in the joint area. An abrupt end to a layer can create an undesirable transition, so the boundaries are determined by the designer.

When laying along a curved path, the ability of the material to maintain its position without folds or tears is assessed. A narrow format does not always help: the behavior depends on the structure and width.

In a serial process, the stacking map must uniquely specify the workpiece number, direction, side and position. A technical article does not replace such a map.

When to select an adjacent shape

If a wide shell or surface is required, a confirmed fabric may be more technologically advanced than a collection of multiple tapes. If the primary process uses a continuous filament or tow, the initial commercial route may be carbon feedstock.

For a finished long part, it is sometimes better to consider tube or rod rather than arrange your own layup. You should compare all the way to the finished element.

  • do not select the ribbon only by width;
  • do not ignore reinforcement direction;
  • do not leave joints without a design solution;
  • do not consider cut fabric to be equivalent to any tape;
  • do not claim a category that does not exist.

Request being verified

Pass layer function, path geometry, width, length, directions, matrix, process, quantity and edge criteria. If there is current material, please include a card and a photo of the packaging.

The specialist will check whether a suitable item exists, whether the confirmed fabric or raw material can be used and what trial stage is needed. Until a response, the feed remains a reference form and not a published product.

For procurement, it is useful to separate mandatory and desirable parameters. The mandatory ones include compatibility with the process, direction of reinforcement and permissible laying geometry; color, packaging or marking method are recorded separately. This separation helps to evaluate the adjacent confirmed form without replacing the original function.

Frequently asked questions

Is reinforcing tape in the current catalog?

A separate confirmed category has not been recorded; Possibility to be confirmed upon request.

Can I cut fabric ribbon?

Sometimes possible, but need to check orientation, edge, stability and transfer technology.

Is the tape always unidirectional?

No. The structure of a particular material cannot be determined only by its shape and name.

How to define a joint?

The position, overlap and end of the layer are determined by the laying map and structural calculations.

Which related category is confirmed?

Fabrics, unidirectional materials and carbon raw materials are represented in the current structure.

What should I include with my request?

Trajectory, width, directions, process, quantity, current specification and result criterion.

Need a choice for a specific task?

Submit dimensions, load, quantity and available files. CORDTEX will clarify the missing data and return with the relevant material or production route.
