The Last Caretaker Carbon Fiber: Where to Get It and How to Farm It

You get Carbon Fiber from High-Tech Scraps. Put them in a Recycler that has power and they come out as Carbon Fiber and Titanium. Look for High-Tech Scraps by name, because the ordinary Tech Scraps are a different item.

High-Tech Scraps come from taking things apart with the dismantle tool. The ones worth hunting are Angels, Talon Sharks, Roller Bois and broken robots, plus LCD Monitors, glass-topped tables, VF-7 Rest Frame beds, Aged Lazarus Vials, Aged Lazarus Seed Containers and empty Human Seed Containers.

Big wrecks hold several: taken apart with the dismantle tool, one Talon Shark gave 4 High-Tech Scraps and one Arch Angel gave 3.

The quickest first Carbon Fiber is in the VF-7 Rest Frame beds near where you start: each one dismantles into 1 High-Tech Scrap.

The first Angels you meet fly around the roof of the Lazarus Complex. Bring one down, dismantle it and carry the scraps to your Recycler.

The CO2 Reactor Tank unlocks at skill tier 22. It is built from 4 Advanced Alloy Mesh, 3 Connector Ports, 4 Alloy Frame, 2 Storage Cylinder, 1 Filtering System, 2 Cooling Radiator, 2 Compression Pump and 1 Storage Matrix, and it holds 12,000 L of CO2.

Run Gas Cable from the CO2 port of a running petrol generator, or from the boat’s exhaust, into the tank, and give the tank power. Every so often a piece of Carbon Fiber drops out of the top. It is slow, so leave it running.

Keep a Gas Cable or a Gas Cable Extender plugged into the funnel on the tank’s top, even one that leads nowhere; with the funnel empty, the CO2 escapes.

While it works it draws 60 kW, so give it its own power supply.

Carbon Fiber goes into three crafted parts: a Magnetic Coil takes 2, a Nano Mesh 2 and a Storage Matrix 3. Machines and weapons need it only through those parts.

Counting those parts, the hungriest build is the Sabatier Reactor at 9 Carbon Fiber. An Electric Rifle needs 4, a Distillation Tower or a CO2 Reactor Tank 3, and a Flamethrower, Lazarus Pod, LumiMax or Rhino Dismantler 2.

Update 6 added the FLO TH-30 Area Heater at skill tier 20. Its one Magnetic Coil makes it 2 Carbon Fiber per heater.

Bringing a broken Lazarus Rack back takes 5 Carbon Fiber, together with 5 Titanium, 10 Gold and common materials such as Plastic and Iron.
