Research on Flexible Resin’s Effect for Composite T-Joint

Abstract:

T-joints are widely used in aeronautics, astronautics and ship structure. They are weak areas in composite structures. Through experiments, flexible resin’s effects on destructive strength and displacement have been researched. T-joints made by 751-059 resin combination have the best performance on displacement and static tensile destructive strength, which reached 21.2 mm and 31.6 KN. Even dynamic tensile destructive strength and stiffness are superior to the T-joints made by HLR-901resin combination, the impact strength is 2.11 times and the impact stiffness is 1.3 times. The basic failure modes of T-joints made by HLR-901 resin or its combination are cementing surface cracking and stratification. But for which made by 751-059 resin or its combination, the basic failure mode is resin snap.
