Frequently asked questions

3D weaving is a technology that produces preforms of three-axis fibers, in a defined geometry and internal pattern, on a dedicated loom.

A 3D woven composite is a 3D preform converted into a final product by resin transfer. Its properties are determined by the fibre, weave pattern and resin system.

The fibres are locked together in three axes, so the layers do not separate (no delamination), and even if a crack forms it cannot run between the layers. Through-thickness fibre raises compression after impact (CAI) and fatigue resistance; high vibration damping lowers the risk of resonance. Test results show 3D woven RTM specimens reaching 813–993 MPa tensile strength and 94–107 GPa flexural modulus; in the same tests, unidirectional (UD) prepreg reached 718–819 MPa and 82–91 GPa, and plain-weave prepreg 420–454 MPa and 39–41 GPa.

OWC stands for One Way Cut: parts are cut from a plate whose fibre is concentrated in one direction, aligned with that direction. The plate in the shop and the products cut from it are made with OWC.

In a 2D carbon plate only the resin holds the layers together. In the OWC plate, through-thickness Z yarns tie the layers: they do not separate on impact or around holes, and wear under repeated loads is lower.

The 500 mm edge. Most of the fibre runs along this axis; the cuttable area is 490 × 240 mm.

Tg is the glass transition temperature of the resin. The plate is made by vacuum-assisted resin transfer moulding (VARTM) and its Tg is 140 °C.

Drone and UAV airframes, civil aviation, automotive, wind energy, marine, and industrial machinery and robotics.

3Dwovens carries out industrial-scale 3D weaving and composite production at its facility in Istanbul. The 3D weaving looms are designed and manufactured in-house, and preforms and composite parts are produced on them.

The plate price is shown on its product page. There is no automatic quantity discount; drone arms, CNC cutting, orders of 25 or more plates and other large-quantity requests are priced through the quote form.

There is no minimum order; a single plate can be ordered. CNC cutting has no minimum order value either; the quote is prepared from the number of plates the order uses and the cutting and setup charges.

No payment is taken on the site. On your request, a proforma invoice is sent by email; payment is made through the PayTR card link in the proforma or by bank transfer (EFT).

An electronic invoice is issued for every order: an e-Invoice if you are registered for e-Invoice in Türkiye, otherwise an e-Archive invoice. For company orders, the company name, tax office and tax number are requested by email when the proforma is prepared; for individual orders, the Turkish identity number is optional. Deliveries outside Türkiye are invoiced without VAT.

For instant dimensions and plate layout, upload a 2D DXF file of up to 5 MB. The outline must be a closed polyline and the part must fit within 490 × 240 mm; units are read from the file and millimetres are assumed when none are set. DWG, STEP, STP and PDF drawings of up to 10 MB are uploaded in the same area. All drawings are priced by quote, and the part price is sent by email.

The part price is determined by quotation, taking into account the number of plates the order uses, the contour cutting length, the number of holes and countersinks, setup and the required lead time. The calculator shows how many plates the order uses. There is no minimum order value. Plate offcuts left from cutting are shipped with the order unless otherwise specified.

No. When a DXF drawing is uploaded, the dimensions and the plate layout are shown; no price is calculated on the page. The drawing is sent with the quote request, checked before production, and the part price is sent to your email address.

It is the direction in which the plate shows its highest strength, running along its 490 mm edge. The load-bearing axis of the part is aligned with this direction; the required direction is stated in the quote request.

Yes. In the Composite cutting calculator you choose which axis of the part is aligned with the strong direction. Aligning the load-carrying axis with the strong direction is recommended; parts longer than 240 mm can only be placed along the strong direction.

Yes. Mounting holes can be drilled directly or finished on a CNC; there is no risk of delamination when machining on a CNC or cutting with a high-pressure waterjet.

The estimated dispatch time is shown on each product page and starts once payment is confirmed. The tracking number is sent to you by email.

Shipping within Türkiye is free. The dispatch time is shown on the lead-time line of the product page. For delivery outside Türkiye, the shipping cost and carrier are sent to you by email once your request has been reviewed, at the rate of our contracted freight agency; the proforma invoice is sent after you accept this amount by replying to the email.

Yes. International orders are placed in USD or EUR; the amount is converted from the TL price at the TCMB forex selling rate and no VAT is applied. Once your request has been reviewed, the shipping cost and carrier are sent to you by email at the rate of our contracted freight agency; the proforma invoice is sent after you accept this amount by replying to the email. Shipping within Türkiye is free.

Standard products can be returned within 14 days of delivery, unused and in undamaged packaging. Details are in the Distance Sales Agreement.

Cylindrical, conical, variable-thickness and curved preforms are woven in a single pass. Carbon, glass, aramid and their hybrids are used; the weave pattern and resin are designed for the application.

The 3D weaving loom, preform and composite production are all carried out in Türkiye under one roof; preforms are turned into composites by vacuum-assisted resin transfer moulding (VARTM). Fully automated weaving gives repeatable quality and a cost advantage at high volumes; the step from prototype to series production is short.

Yes. For custom production requests a mutual non-disclosure agreement can be signed before drawings are shared; tick the NDA option in the request form.
