Study on Axial Compression Performance of CFRP-Aluminum Alloy Laminated Short Tubes. [PDF]

Materials (Basel)
CFRP possesses the advantages of lightweight and high strength, but its cost is relatively high, and its ductility is insufficient; aluminum alloys have a relatively low cost and good ductility. This paper develops a CFRP-aluminum alloy laminated tube (CFRP-AL tube), which combines the advantages of CFRP and aluminum alloy.
