• showed that both Young’s modulus (by 38%) and ultimate tensile strength (by 62%) could be increased by introducing V-shaped interfaces. Digital image correlation analysis and the fracture images showed that the positioning of the area with the highest glass fiber content can lead to spatial control over

• (Supporting Information File 1, Figures S3 and S13) [52]. Digital image correlation and tracking (DICT) was used to measure the strain during the loading ramps [53]. DICT was done twice per data set, once on the edges of the PTP to subtract the force coming from the PTP spring, and once on the edges of the
