EFFECT OF ANGULAR RADIUS SIZE AND SANDBLASTING PROCESS ON FAILURESTRENGTH OF T-SHAPED PLATE JOINTS OF COMPOSITE SHIPS

Abstract

Abstract: T-plate joints of composite components are widely used in naval structures, which are the weak parts of the mechanical properties of naval structures. The effects of structure size and manufacturing process on the failure strength and deformation of joints were studied experimentally. The failure strength of T-joint increases with the increase of the turning radius, and decreases when the radius exceeds R50 mm. The failure load and displacement of sandblasted specimens are 2.1 and 2.16 times higher than those of non-sandblasted specimens. When the air pressure reaches 0.6 MPa and the injection time is 100 s, the failure strength increases slowly.

Key words: composite ship, T-joint, structure and technics, destructive strength
