Özet

Hybridizing basalt with carbon is a route to tailor tribological performance of polymer laminates.
This study quantified how the surface ply governs friction and wear under Hertzian reciprocating contact.
Epoxy laminates with 0/90 woven carbon and basalt were vacuum infused in four eight-ply sequences: 8B,
8C, 2B4C2B, and 2C4B2C. Tests at 30 N, 2 Hz, and 50 m recorded friction and 3D topography of wear
tracks. Responses separated by the outer lamina. Carbon-skinned 2C4B2C gave the lowest friction,
sustaining 0.06–0.07 and the smallest footprint, 653 μm wide and 7 μm deep. All-carbon 8C remained
similarly low, drifting to 0.08–0.09 with 649 μm and 8 μm. Basalt-skinned 8B rose toward 0.45–0.50 and
produced the largest groove, 1602 μm wide and 128 μm deep, while 2B4C2B transitioned mid-distance to
0.48–0.52 with 1180 μm and 76 μm. Topographies corroborated these trends, showing shallow polishing
for carbon skins but deep valleys and spallation for basalt skins. Higher stiffness and thermal conductivity
of carbon stabilize a lubricious film and limit matrix softening and third-body formation. Carbon as the
outer lamina minimizes frictional heating and material loss; basalt is better reserved for sub-surface roles
when contact stability is critical. These findings guide hybrid design for aerospace tribo-contacts.
