Materials / Data sheet

Carbon-fiber PPA PPA-CF

Under-hood parts and tooling that runs hot and wet.

In plain words

Good for

Under-hood parts and tooling that runs hot and wet.

Not for

Strong acids or alkalis. Flame, sparks or high-current electrics (it is a nylon).

Upright is weaker

A printed part is strongest along its layers (flat, X-Y) and weaker across them (upright, Z). The table shows both. We turn the part so the load runs along the layers.

The full data sheet

Every number on this page is copied from the filament maker's technical data sheet (V1.0). The PDF has the test methods and print settings.

Test conditions from the data sheet: not stated dry/conditioned; specimens X1C, chamber 52 °C, not annealed. These are lab numbers for test bars, not a working limit for your part. The real limit depends on the load, the time at temperature and the shape, which is why we ask about all three.
