Study on Tensile Properties of Double-Double Laminates
摘要
There are many design criteria for traditional composite laminates, which lead to low design efficiency and high cost. Double-Double (DD) laminate structure breaks through the limitations of traditional laminate design criteria, and has higher design efficiency and lightweight advantages under the condition of equivalent stiffness and strength. In this paper, the performance advantage of DD laminate structure is verified by tensile test of two kinds of laminate structure. DD laminate structure has higher design efficiency and lightweight potential.
