Influence of autoclaving process parameters on the buckling and postbuckling behaviour of thin-walled channel section beams

• We produce GFRP laminates with different manufacturing parameters using autoclaving technique.
• We perform mechanical and structural tests to find material properties.
• The finite element models of thin-walled channel section beam made of laminate have been prepared.
• We check the influence of lay-up and autoclaving parameters on buckling and failure load of considered beams.

The postbuckling behaviour and load carrying capacity of thin-walled composite channel sections subjected to uniform compression are presented. An analysis of the influence of parameters of the composite manufacturing process on strength properties and load carrying capacity of the thin-walled structure made of this composite has been conducted. The microstructure characteristics of composites is presented and discussed. The postbuckling behaviour and load carrying capacity of thin-walled channel section columns subjected to compression have been determined with the finite element method. The ANSYS software has been employed.
