To promote the usage of recycled composite material, it is of paramount importance to develop quality control and property assurance methodologies compatible with the format of reclaimed fibers. In this paper, the concept of using interlaminated hybrid specimens, whose tensile response has been tailored with the aid of the Damage mode maps, is exploited to unambiguously identify the reclaimed fibers failure strain. The interlaminated hybrid specimens are manufacturing by sandwiching a layer of aligned discontinuous reclaimed carbon fibers produced with the HiPerDiF (High Performance Discontinuous Fibre) method between continuous glass fibers. The reliability of the obtained results is compared with results obtained with single fiber tensile tests. The developed methodology is then applied to the investigation of the strength retention of carbon fibers reclaimed through a solvolysis process and to the effects of the fiber length on the HiPerDiF alignment process.
