Carbon and basalt hybrid anchors beat pure basalt bars in lab tests
Source: Mechanics of Composite Materials, "Mechanical properties and anchoring performance of carbon/basalt fiber hybrid composite anchors", published 11 November 2026.
What the source says
Specimen-scale carbon/basalt hybrid anchors with 8, 10 and 11 vol% carbon fibre were tested in tension and shear. At 10 vol% carbon fibre, tensile and shear strengths were 862 MPa and 190 MPa, above pure BFRP, and pull-out in M40 mortar exceeded HRB400 rebar.
Allbase view
Specimen-scale lab tests on hybrid carbon/basalt anchors, with no field or long-term durability data yet. Promising as a rebar alternative in ground anchoring, but there is nothing to act on yet for anyone specifying reinforcement.
