Tensile Properties of Flax Fibre Bundles with Graphene Oxide Coating

Farzin Javanshour of Tampere University reports the effect of a 1.2 wt% graphene oxide coating on the tensile behavior of single flax fibre bundles. The dataset includes results for four treatment subclasses: as-received fibres, fibres soaked in water for 30 minutes, fibres soaked for 24 hours, and fibres treated with graphene oxide for 24 hours. Tensile properties were measured using the impregnated fibre bundle test method with an Instron 5567 machine and a 30 kN loadcell.

Use Cases

• Compare the tensile strength of flax fibres with and without graphene oxide coating based on the four treatment subclasses.
• Analyze the effect of water immersion on flax fibre tensile properties based on the '30 min' and '24 hr' control groups.
• Model stress transfer in composite materials based on the described hydrophilic bonding of graphene oxide to technical fibres.

Strengths

• The dataset is structured to isolate the effect of graphene oxide treatment by including three distinct control groups.
• Testing was performed under controlled environmental conditions (50% RH, 25°C) with a 50 mm clip-on extensometer for strain measurement.
• Specific material sources and preparation methods are documented, including the use of AmpliTex 5009 flax fabrics and a modified Hummer's method for graphene oxide dispersion.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
• The description notes that tensile test data for single natural fibres is 'very scattered' due to non-homogenous structure and non-standard methods.
