Three-dimensional strain test results of GO-modified CFRP composites (a1, b1, and c1: Sample morphology during the tensile process; a2, b2, and c2: longitudinal strain; a3, b3, and c3: longitudinal displacement; d1, d2, and d3: Sample morphology at tensile fracture moment).

(a) GO 0% strain

(b) GO 0.05% strain

(c) GO 0.1% strain

(d) Fracture morphology (d₁:GO 0%; d₂:GO 0.05%; d₃:GO 0.1%
