摘要

Carbon thermoplastic (AS4/APC-2) to Titanium (6Al-4V) bonded and bonded/bolted joint designs were developed for use in the marine, Composite Storage Module (CSM) for the Office of Naval Research. Finite element modeling of the design was done using PATRAN and subsequent analyses were performed using the ABAQUS finite element code. In order to validate the design and to provide a measure of confidence with the fabrication and assembly of the joint, three, full-scale test specimens were designed, fabricated and tested in a representative tensile load environment. The three joint specimens were fabricated by Production Products and tested at the Naval Surface Warfare Center, Carderock Division. The carbon specimens were 1.04 m (40.9 in.) in length by 0.254 m (10 in.) in width by 28.5 mm (1.12 in.) in thickness and captured in the 70 mm (2.75 in.) thick titanium. Two of the specimens were bonded joints and the third was a bonded/bolted joint. The specimens were subjected to three cycles of tensile loading on a 2447 kN (550 kip) MTS test machine with the last loading cycle to failure. One bonded joint specimen failed in the adhesive bondline at 378 kN (85 kips) and the second bonded joint failed at 600 kN (135 kips). The bonded/bolted joint specimen showed adhesive failure at 489 kN (110 kips) and complete failure in the bolts at 556 kN (125 kips). This paper discusses the theoretical predictions, experimental results and correlation.
