Experimental_TensiletestR036-R038_T3.4.2_DLR

Tensile tests were carried out to characterize the mechanical properties of conditioned flax-PA11 composite specimens. The specimens were exposed to controlled environmental conditions representing the range of temperature and humidity expected during aircraft operation. The testing aims to understand how these parameters affect the tensile performance and structural integrity of the biocomposite material. Standardized specimens according to DIN EN ISO 527 with dimensions 25 mm × 250 mm were used. Specimens were equipped with bonded load introduction tabs to ensure uniform stress distribution and prevent premature failure at the grips. Mechanical testing was performed on a Zwick Roell 100 kN universal testing machine, and deformation measurements were conducted using a Digital Image Correlation (DIC) system (LIMES, Instra4D software) for full-field strain analysis.
