TESTS ON LAYERED DOUBLE-LAP COMPOSITE T-JOINTS

Abstract

This study represents an intermediary stage to optimize layered double-lap composite T-joints (CTJs) used to stiffen firefighter water tank walls and to restrain the water flow inside these tanks. CTJs with different width-to thickness ratios and identical laminates architectures have been fixed on a specially designed table at different clamping lengths and their baffle have been subjected to static tensile loads until break. Further stage in the optimization process is required. More efficient CTJs clamping methods have to be designed restraining only the displacement of the double-lap connection laminate on their thickness.
