This hub is built for one job: turning the OSB catalog into a shortlist. Whether you are comparing carbon fiber material suppliers for a first production run or simply need to pin down a ply thickness before tooling is cut, the tables and decoder below start from the part and work back. Every model number in the catalog resolves to a specific combination of fiber grade, areal weight, weave and tow width, so a carbon fiber spread tow fabric can be matched to your laminate rather than guessed at.

Which Spread Tow Fabric Goes Into Your Part?

Start from the part, not the datasheet. The catalog does not hide behind a single SKU: it lists dozens of distinct grades — OSB CFF65 P 25, OSB CFF133 P 12, OSB CFF206 P/T 16 — and each one pairs a fiber grade with an areal weight, a weave structure and a tow width. Choosing between them is a design decision, and it is the decision this page is built to support.

The technology behind the choice is straightforward. In spread tow fabric, the filament tow is opened into a flat, wide band before weaving. The product page states that this produces excellent fiber alignment and fewer warp–weft interlacing points, which reduces resin accumulation and porosity during prepreg processing and enables easy impregnation and laying. Composites manufactured with this fabric are described as showing superior interface performance and high mechanical properties, with design flexibility for final composite parts.

Everything below is a working tool rather than a brochure. The decoder explains what each character in a model number means, the master table lists every grade in the catalog with its reference thickness, and the scenario matrix converts a part requirement into a shortlist you can take straight to a sample request.

Model numbers

Decode the Part Number: CFF80 P 5

Every OSB fabric is named with the same four-part logic. Read it once and the entire specification table below becomes scannable.

Segment 1

CFF

Carbon Fiber Fabric — the product family prefix on every listed model.

Segment 2

Fiber areal weight in g/m² (gsm). In CFF80 it is 80 gsm.

Segment 3

Fabric structure code — here P stands for plain fabric.

Segment 4

Width of a single spread tow, in mm (or as specified).

Plain weave — the structure shown by a single P in a model number.

Twill weave — listed alone or alongside P where the model offers a choice.

Satin weave — appears with P/T on models such as OSB CFF80 P/T/S 20.

* Thin-ply featured product. Any fiber areal weight marked with an asterisk in the table is flagged on the product page as a thin-ply featured product. A model without the asterisk is listed at its standard weight — the asterisk is a catalog rule, not a performance claim about the fiber grade.

Selection

Scenario-to-Specification Selector

Four common starting points, each mapped to models that already exist in the catalog — with the question you should answer before requesting a sample.

Ultra-thin prepreg

Very low ply thickness, high ply count

Thin-ply marked grades run from 52 g/m² (OSB CFF52 P 20, 0.05 mm) up to 133 g/m² (OSB CFF133 P 12, 0.13 mm).
The finest reference thickness in the catalog is OSB CFF52 P 20 at 0.05 mm.
M30 and T700-12K groups carry the largest number of thin-ply options.

Buyer decision Confirm how many plies your cure cycle and press can handle before going thinner — thinner plies multiply lay-up time.

Structural laminate

Standard-weight load-bearing plies

The 160–206 g/m² band is listed without a thin-ply asterisk: CFF160 P 10, CFF200 P/T 8, CFF165 P/T 20, CFF183 P 18, CFF206 P/T 16, CFF206 P 10.
Reference thickness in this band runs from 0.16 mm to 0.21 mm.
T700-24K and T800-24K groups appear only in this higher-weight band.

Buyer decision Decide whether the laminate is defined by ply count or by target thickness — the two lead to different columns in the table.

Drape-critical shapes

Curved tools and non-flat geometry

Weave choice beyond plain exists at 80 g/m² (P/T/S 20), 88 g/m² (P/T/S 18), 100 g/m² (P/T 16 and P/T 20) and 200 g/m² (P/T 8).
Satin weave is listed only on OSB CFF80 P/T/S 20 and OSB CFF88 P/T/S 18.
Twill is offered on eight catalog models across the T700 and T800 groups.

Buyer decision Trial the weave on your own tooling. If the catalog structure you want is not listed, structure can be customized — ask before settling for plain weave.

Visible & cosmetic parts

Surfaces that stay on show

Satin and twill structures are available at 80 g/m² and 88 g/m² in the T700-12K group.
A colored, spread-tow and metallized variant is supplied on the same product page.
That variant is described as retaining lightweight, high-strength characteristics while adding metallic properties through surface metallization.

Buyer decision Choose the weave first for the surface effect you want, then confirm the areal weight that fits your ply schedule.

Trade-offs

Three Variables That Change the Shortlist

Thin-ply versus standard weight

The asterisk is the fastest filter in the table. Asterisked weights span 52 g/m² to 133 g/m² and are the company's thin-ply featured products. Everything from 160 g/m² upward in the T700-24K, T800-24K and high-weight T700-12K rows is listed without the asterisk.

Decision point: thin-ply buys you thickness control per ply, but it also means more plies, more lay-up time and a tighter cure window.

Plain, twill or satin

The structure code sits in the third position of every model number. Most of the catalog is plain weave. Twill and satin appear only where the row says P/T or P/T/S — at 80, 88, 100 and 200 g/m² in the T700-12K group.

Decision point: if your part is not flat, look at the multi-structure rows first; if the structure you need is not listed, it can be customized.

Tow width and fiber alignment

Tow width is stated for every model and runs from 4 mm (OSB CFF100 P 4) to 25 mm (OSB CFF65 P 25, OSB CFF80 P 25, OSB CFF132 P 25, OSB CFF83 P 25, OSB CFF61 P 25). It is recorded in millimetres or as specified.

Decision point: read tow width together with areal weight — the pair sets both the look of the weave and the reference thickness of the ply you are buying.

Custom Structure, Custom Width, Priced to Your Drawing

The catalog gives you the starting point; the order is built around the part. Fabric structure and other specific specifications can be customized according to customer requirements, and the listed 1000 mm width is the standard — not the limit — of what can be discussed.

Frequently Asked Questions

what does the model number cff80 p 5 tell me?

it decodes in four parts: cff stands for carbon fiber fabric, 80 is the fiber areal weight in g/m² (gsm), p indicates fabric structure as plain fabric, and 5 is the width of a spread tow in millimetres (or as specified).

what do the p, t and s codes stand for?

p is plain weave, t is twill weave and s is satin weave. a model such as osb cff80 p/t/s 20 can be supplied in any of the three structures, while osb cff133 p 12 is listed as plain weave only.

what is the standard fabric width?

all fabric products listed in the specification table have a standard width of 1000 mm. fabric structure and other specific specifications can be customized according to customer requirements.

what does the asterisk next to a fiber areal weight mean?

fabrics marked with an asterisk (*) in the fiber areal weight column are the company's thin-ply featured products. asterisked weights in the current catalog range from 52 g/m² to 133 g/m².

can i order a custom weave structure or a different width?

yes. fabric structure and other specific specifications can be customized according to customer requirements. share your target areal weight, weave code, tow width and required width through the contact page and the specification can be set against your drawing.

which fiber grades are covered in the catalog?

the table is grouped by t300-3k, t700-12k, t700-24k, t800-12k, t800-24k and m30 grade carbon fiber. t700-12k carries the widest spread of areal weights, from osb cff65 p 25 at 65 g/m² up to osb cff200 p/t 8 at 200 g/m².
