摘要: Abstract Composite plates made of satin weave fabric show macroscopic anti-symmetry and coupling effects. The essential mechanism such behaviour is explained. Closed-form solutions the upper lower bounds stiffness compliance are obtained by simplest series model in connection with uniform stress strain assumptions. Finite element analyses using three-dimensional isoparametric elements also conducted. fall between both within a certain limit. deviation actual quasi-micromechanical conditions from simple assumptions can be seen FEM results. Rough estimation thermal warping coefficients carried out for carbon-epoxy glass-polyimide 8th harness composites measurements. More accurate results provided experiments measuring deflection under small temperature change. These experimental confirm theoretical predictions methods. Several comments purpose preventing phenomena, based on geometry structures.
