Abstract:
The work at hand describes the influence of the bond properties between carbon textile reinforcement and strainhardening cement‐based composites (SHCC) on the composite tensile behavior. The SHCC matrix was reinforced with 6‐mm long micro‐fibers made of ultra‐high molecular weight polyethylene (UHMWPE) in a volume ratio of 2%. For emphasizing the benefits of hybrid fiber reinforcement, the cementitious matrix with 0% short fibers was reinforced with carbon textile only. Specially designed specimens were tested in tension under a displacement rate of 0.05 mm/s. The deformation, crack formation and fracture of the tested specimens were monitored optically and subsequently evaluated using Digital Image Correlation (DIC).
