Aramid-reinforced polyamide. No aramid-filled nylon filament was found in any catalogue searched — every aramid filament on the retail market uses an ASA matrix — so on the evidence available this category is misplaced under PA and belongs with ASA. It carries the availability finding and family-level handling notes only.
Applications
Aramid-reinforced nylon has a real engineering role in wear-resistant compounds. RTP lists PA66 grades containing aramid fibre, including formulations that also contain PTFE, in its tribological portfolio. The purpose is to tune sliding wear and friction in mating components; the material should not be treated as an interchangeable substitute for a stiffness-focused carbon-filled nylon. Fibre type, lubricant package and counterface jointly determine the useful advantage.
RTP tests an aramid-and-PTFE PA66 formulation against 1018 C steel at several pressure–velocity conditions, illustrating how contact conditions govern wear and friction. The complete additive package matters; an aramid-only compound cannot inherit PTFE-containing results. These are molded-compound data rather than FDM results, and availability of the engineering compound does not establish an off-the-shelf aramid-nylon filament.

16 documented fieldsProperties & source data
Open a topic to explore the complete data. Each value keeps its original conditions, units and dated sources.
Material & market2 fields
| Property and unit | Published value and conditions | Sources and dates |
|---|---|---|
| Base polymer / chemistry | Aramid-fibre reinforced polyamide | 1 source
|
| Market availability (1–5) | Special order, 1–2 makers worldwide — no aramid-filled nylon filament was found in any catalogue searched; the aramid filaments that do exist in the retail market use an ASA matrix | 2 sources
|
Print settings1 field
| Property and unit | Published value and conditions | Sources and dates |
|---|---|---|
| Enclosure / chamber requirement (1–5) | Enclosure required (passive) — as for every nylon | 1 source
|
Nozzle wear & reliability3 fields
| Property and unit | Published value and conditions | Sources and dates |
|---|---|---|
| Nozzle hardness required (1–4) | Hardened steel required — no aramid-filled nylon datasheet was obtainable; Polymaker measures about 9 h of brass nozzle life on its fibre-filled nylons | 1 source
|
| Abrasiveness (1–5) | Highly abrasive — fibre-reinforced nylon composite | 1 source
|
| Nozzle clog risk (1–5) | High — jams from moisture, heat creep or particles; nylon already needs a drybox and Prusa names kevlar among the fibres that raise nozzle-clogging risk | 1 source
|
Moisture & drying2 fields
| Property and unit | Published value and conditions | Sources and dates |
|---|---|---|
| Moisture absorption (hygroscopicity) (1–5) | Very high (>2 %) — the polyamide matrix governs uptake | 1 source
|
| Effect of moisture on strength | Polymaker's printed dry-versus-wet blocks for its CoPA nylon show what conditioning does to the family: tensile 78.0 → 34.3 MPa and modulus 2703 → 724 MPa, with notched Charpy rising 6.9 → 27.7 kJ/m². Fibre reinforcement reduces but does not remove the effect | 2 sources
|
Health & safety5 fields
| Property and unit | Published value and conditions | Sources and dates |
|---|---|---|
| Fume toxicity (1–5) | Moderate — measurable VOCs and UFPs, ventilation advised | |
| VOC emission rate (µg/min) | Up to 180 caprolactam, the dominant VOC from nylon and the largest single-VOC rate in the study | |
| Ultrafine-particle emission rate (particles/min) | ≈2 × 10⁸ median for nylon — low for particles despite the highest VOC mass measured | |
| Hazardous species emitted | Caprolactam, at up to 180 µg/min from nylon filament | |
| Ventilation / filtration requirement (1–5) | Ventilated room or enclosure recommended |
Solvents & solubility3 fields
| Property and unit | Published value and conditions | Sources and dates |
|---|---|---|
| Soluble in | Formic acid, phenol, m-cresol and hexafluoroisopropanol dissolve the matrix at 23 °C, leaving the fibre; laboratory reagents. | 1 source |
| Softened or crazed by | Zinc chloride solutions stress-crack the nylon matrix, alcoholic calcium chloride dissolves it, mineral acids attack it. | 1 source |
| Solvent welding & smoothing agent | None — nylon's only solvents (formic acid, phenol, HFIP) degrade the part, and the fibre blocks surface flow anyway. | 1 source |
How to read these values
Values describe representative grades, not every spool. Manufacturer datasheets and independent tests retain their source labels and dates. Printed orientation, test method, conditioning and formulation can change results. Unknown values are —. A listed use is not a certification. Shore A, Shore D and Rockwell hardness are separate scales.
