B 4 C‐nanowire/carbon‐microfiber hybrid structures are synthesized using cotton T‐shirts as both the template and carbon source. The B 4 C nanowires exhibit a high elastic modulus of 428.1 ± 9.3 GPa and elastic recovery after multiple high‐strain bending cycles without brittle failure or obvious residual deformation for the strain up to 45%. The hybrid structures can block 99.8% UV irradiation and achieve a superior reinforcing effect in epoxy composites.
