Tensile Behavior of Symmetrical Laminates Made of PCBA and PMMA Layers

摘要: The stiffness and strength of a composite material in form laminate is obtained from the properties constituent laminae. stacking sequence affects mechanical behavior. interface be- tween different laminae also an important factor, since it influences stresses that are developed laminate, hence strengths. In this study, theoretical investi- gation behavior symmetrical laminates made isotropic layers (Lexan (PCBA) Plexiglas (PMMA)) was attempted. An analysis based on lamina- tion theory performed to determine stress distribu- strains as well elastic constants. Experimental measurements with specimens dif- ferent sequences were carried out. values compared given by lamination mechanics materials approach. © 2006 Wiley Periodicals, Inc.
