Effects of Cryogenically Treated CFRP Composite on the Buckling Behavior in the Adhesively Bonded Beam

Carbon fiber reinforced plastic (CFRP) composite materials have favorable mechanical and physical properties such as low density, high strength-to-weight ratio, fatigue resistance creep behavior, stiffness. Thanks to these unique properties, they produce aircraft parts outer flaps, carry-through structures, center wing boxes automotive body panels, engine components, structure members. However, studies been continuously performed on improving the of CFRP materials. Recently, investigation effects cryogenic (LN2) cooling behavior characteristic is getting a popular important issue. In this sense, study aims examine buckling behaviors adhesively bonded beam-produced cryogenically treated carbon (Cryo-CFRP), CFRP, steel, aluminum. Therefore, new finite element model was adopted evaluate capacity Cryo-CFRP material in beam. The supported adhesive beam subject two opposite-edge compressions until buckles. elastic, homogeneous used assembly. Finite models for having four different adherents (CRFP, Cryo-CFRP, aluminum) were established by ANSYS® software. critical loads predicted, their mode shapes presented first six modes. usage load investigated. Among adherents’ materials, highest determined Cryo-CFRP/Steel 23.6 N. This value obtained 22.3 N CFRP/Steel adherent samples. Thus, increased 5.6 % when one steel constant other changed from Cryo-CFRP. Also, 3.7 using Cryo-CFRP/Aluminum couple instead CFRP/Aluminum sandwich findings demonstrated that treatment positively affects
