Details of mechanical tests.

Test	Specimen dimensions	Fixture	Displacement rate	Standard
Compression	140 mm long x 70 mm diameter	Flat steel platens	10 mm/min	Cylindrical sample with 2:1 ratio of length:diameter (Elsacker et al., 2019)
Tension	260 mm × 27 mm x 42 mm	Flat, serrated steel clamps; distance between clamps 140 mm at start of test	5 mm/min	Based on BS EN ISO 527–4:1997 - Plastics. Determination of tensile properties. Test conditions for isotropic and orthotropic fibre-reinforced plastic composites
Bending	260 mm × 27 mm x 42 mm	3 point bending fixture with a span of 110 mm between the supports	10 mm/min	Based on BS EN ISO 14125:1998 Fibre-reinforced plastic composites. Determination of flexural properties

Note: sample dimensions given are the dimensions of the molds. Due to a combination growth after being removed from the mold, followed by shrinkage during drying, final dimensions varied by approximately ± 5%. Each specimen was measured three times in each direction before testing, and the average of the three values was used for stress calculations for each specimen.
