Analysis of ILSS tests of continuous fiber reinforced composite specimens produced by 3D

Abstract

3D printing technologies are one of the major current trends in the manufacturing and prototyping of structural elements, with recent developments focused on the production of polymer matrix composites. The objective of this study is to analyze the results of interlaminar shear tests performed on monolithic composite materials of thermoplastic matrix reinforced with continuous fiber. The test specimens were manufactured with a MarkOne 3D printer using different filaments reinforced with glass fiber, aramid fiber and carbon fiber, which were later cut and tested according to EN2563. In the case of the carbon fiber specimens, results from the ILSS test have been obtained, which will be used to carry out comparative analysis. However, for the glass fiber reinforced specimens no valid results have been obtained, undergoing plastic deformation during the test. The aramid fiber reinforced specimens could not be tested since they suffered softening due to the heat generated during the cutting process. These activities are included in the FACTORIA project, financed by the Ministerio de Economía y Competitividad a través del Centro Tecnológico Industrial (CDTI) within the framework of the Strategic Program CIEN 2016.
