CERES Project has been successfully completed. All the main objectives were accomplished:
TEST01 covered the mechanical characterization of novel prepreg coupons at RT and HW, manufactured by ELEMENT. These tests were executed in the first reporting period (RP1) and results were reported in deliverable D1.1.
In TEST02 the mechanical properties of a TP material (tension, compression, filled hole tension, CAI…) were assessed, including the use of HSC. These tests were executed in the RP1 and results reported in deliverable D2.1.
TEST03 comprised the execution of unfolding tests and static tests on high load frames under representative boundary conditions. These tests were performed in the second reporting period (RP2), and results reported in deliverable D3.1.
In TEST04, several repair solutions and laminates were evaluated for TS and TP composites, including the assessment of ageing. Complementary tests were performed on TP coupons. These tests were completed in RP2, and results included in deliverable D4.1.
TEST05. The work performed in TEST04 was upscaled. The mechanical behaviour of repair technologies was assessed by means of compression tests on aged TS and TP T-stringer specimens. These tests were completed in the RP2 and results reported in deliverable D5.1.
TEST06. CAI performance of different laminates was evaluated. ELEMENT developed a new impact tower for low-energy impacts (BVID). These tests were completed in the RP2 and results included in deliverable D6.1.
TEST07 covered the mechanical characterization of T-Joint specimens, evaluating different composite materials and thickness. These tests were completed in the RP2 and results reported in deliverable D7.1.
TEST08 was the last stage of repair technologies validation initiated in TEST04. TP and TS SRO specimens including repairs were subjected to static and fatigue tension tests. These tests were executed in the RP2 and results reported in deliverable D8.1.
The results of this Project have been disseminated through different channels, such as the Project website. ELEMENT participated in the NEWFRAC Workshop, where the progress on CERES Project was presented. ELEMENT also participated in the National Congress on Composite Materials (MATCOMP21), where a banner of ELEMENT stand was dedicated to CERES and three publications related to the Project were presented.
The work performed on advanced monitoring techniques in this Project, especially on DIC, has been attractive for the Topic Manager and AERNNOVA. Thus, this way of testing strain monitoring will be further investigated.
