## Crack growth in a 2D laminate and a 3D weave

In a 2D laminate a crack runs along the resin line between layers and the layers separate. In a 3D weave, Z yarns bind the layers through the thickness; the crack stops at the first Z yarn.

1. A crack starts at the edge of both plates.
2. In the 3D weave, Z yarns through the thickness stop the crack.
3. In the 2D laminate, the crack runs between the layers and the layers separate.

- **Around holes:** No cracking around holes, so bolts can sit close to the edge.
- **After impact:** Impact energy spreads through the whole structure, so parts don't snap.
- **Machining:** Machines like metal on CNC and waterjet, with clean edges.
- **Repeated missions:** With no separation between layers, wear under vibration and repeated loads is lower than in a 2D laminate; parts last longer in repeated missions.

## Test values

Tensile strength and flexural modulus values are test results on 3D woven RTM specimens.

| Property | Value |
|---|---|
| Tensile strength | 813–993 MPa (3D weave + RTM) |
| Flexural modulus | 94–107 GPa (3D weave + RTM) |
| Density | ≈1.60 g/cm³ (Approximate value) |
| Glass transition temperature (Tg) | 140 °C (VARTM-moulded plate) |

## Product groups

### Full plate

Structural carbon plate, 500 × 250 × 6.5 mm, Tg140. For R&D teams that cut on their own CNC and prefer not to share their design.

$612 (export price, no VAT) · [View the plate](https://3dwovens.com/en/products/owc-plate.md)

### Composite cutting (CNC)

Parts CNC-cut to your drawing. The part is cut from 3D woven plate and shipped; the price follows the plates used.

### Ready-made drone arms

5, 7, 9, 10, 12 and 15 inch; set of 4. Arms for FPV, long-range and heavy-lift drones that damp vibration and impact and make PID tuning easier.

## How ordering works

1. **Choose a product or upload your drawing.** Plates, sample kits and drone parts are in the shop; your drawing is all a custom cut needs.
2. **See the price.** Catalogue prices are on each product page; a cutting price is calculated as soon as the drawing is uploaded.
3. **Pay by link.** Once the order is approved, a PayTR payment link is emailed to you; payment is made by card.
4. **Track the shipment.** The tracking number is sent to you by email.

## Material comparison

Numerical values are sourced; the other rows are a qualitative comparison.

| Property | 3D weave (OWC) | 2D twill (plain-weave prepreg) | UD prepreg | Al 6061-T6 |
|---|---|---|---|---|
| Tensile strength (MPa) | 813–993 | 420–454 | 718–819 | 310 |
| Flexural modulus (GPa) | 94–107 | 39–41 | 82–91 | 68.9 (elastic modulus) |
| Density (g/cm³) | ≈1.60 | No sourced value | No sourced value | 2.70 |
| Delamination | Does not occur; Z yarns bind the layers | Risk of separation along the resin line between layers | Risk of separation between layers | No layered structure |
| Around holes | No cracking at holes near the edge | Risk of layer separation around holes | Risk of splitting along the fibres | Isotropic; edge distance rules apply |
| After impact | Damage stays local; no sudden failure | Internal delamination, lower compressive strength | Internal delamination and fibre splitting | Permanent deformation (denting) |
| CNC edge quality | Clean edge, no fraying | Risk of fibre breakout and fraying at the edge | Edge splitting depending on fibre direction | Clean edge; needs deburring |

## Where it is used

The product group that fits each field: ready-made arms, full plate, composite cutting or custom production.

- **FPV freestyle and racing:** Arms whose layers do not separate, for 5 and 7 inch builds that crash often.
- **Long range:** Arms for 7–10 inch long-range drones with 16×16 and 19×19 motor patterns.
- **Cinelifters and heavy cameras:** Arms for 9–15 inch platforms carrying cinema cameras; custom body parts are cut from the full plate.
- **Search and rescue:** 10–15 inch arms for the thermal-camera UAVs of volunteer search and rescue teams such as AKUT; their layers do not separate on impact.
- **Crop spraying and monitoring:** 12–15 inch arms are for monitoring and light spraying prototypes; body parts for large spraying UAVs are cut to your drawing.
- **Industrial inspection and mapping:** Arms for 9–12 inch inspection and mapping drones carrying a camera or LiDAR.
- **Cargo and delivery prototypes:** Load-carrying body and bracket parts are made from the full plate or cut to your drawing.
- **University and Teknofest teams:** Full plate and cutting to your drawing for competitions and thesis work.
- **Defence and aerospace R&D:** Full plate and composite parts woven in one piece to your design; NDA on request.

## Frequently asked questions

### How are prices set?

Prices of plates, sample kits and drone parts are shown on each product page. A CNC cutting price appears in the calculator as soon as you upload your drawing. There is no automatic quantity discount; orders of 25 or more plates and other large-quantity requests are priced through the quote form on the contact page.

### How long does delivery take?

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.

### Which file format is accepted for cutting?

For an instant price, 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; they are priced by quote and the part price is sent by email.

### Why is a 3D woven composite more durable?

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.

### How is the invoice issued?

Every order is invoiced electronically: an e-Invoice if you are registered for e-Invoice in Türkiye, otherwise an e-Archive invoice. For company orders, enter the company name and tax details in the order form. Deliveries outside Türkiye are invoiced without VAT.
