Bambu PAHT-CF

Bambu PAHT-CF is a composite of PA12 and carbon fibers. Thanks to the advantages of the low water absorption of PA12 and high-performance carbon fibers, Bambu PAHT-CF provides excellent mechanical and thermal properties, which it maintains even when in contact with water. Higher Z-axis layer adhesion and flexibility make it ideal for producing engineering parts such as functional prototypes, machining jigs, injection molds, fixtures, and parts for small-batch production.

Low water absorption

With 50% lower water absorption compared to standard PA-CF, Bambu PAHT-CF maintains excellent mechanical properties and dimensional stability even when exposed to high humidity.

Comparison of mechanical properties

Filament	Saturated water absorption/% (25 °C, 55% RH)	Flexural strength - XY/MPa (Dry state)	Flexural strength - XY/MPa (Wet state)	Flexural modulus - XY/MPa (Dry state)	Flexural modulus - XY/MPa (Wet state)	Drop in mechanical properties after water absorption/%
Standard PA-CF	1.70	128	76	4420	2210	40%-45%
Bambu PAHT-CF	0.88	125	115	4230	3640	12%-18%

Exceptional Z-layer adhesion

Bambu PAHT-CF exhibits much higher Z-axis layer adhesion compared to standard PA-CF, allowing it to withstand high levels of impact or load without cracking or deforming.

Z-layer performance

	Standard PA-CF	PAHT-CF	Improvement %
Flexural strength - Z/MPa	48	61	27%
Flexural modulus - Z/MPa	1470	1820	24%
Impact strength - Z/kJ/m²	5.7	13.3	133%

High tensile strength

Bambu PAHT-CF is designed to meet the demands of various industrial and engineering applications where high strength and durability are required.

Designed for high heat resistance

The heat deflection temperature of PAHT-CF under flexural load is up to 194°C (0.45MPa), making it useful for applications where printed parts are exposed to high temperatures without deformation or loss of strength.

Reusable spool

Bambu PAHT-CF comes with a high-temperature-resistant spool that is not prone to deformation during the drying process. This spool is reusable with other Bambu refills, helping to reduce plastic waste.
