Thermal cycling of composite laminates made of out-of-autoclave materials

Autor: Mahdavi Soheila, Gupta Shambhu Kumar, Hojjati Mehdi

Publikováno v: Science and Engineering of Composite Materials, Vol 25, Iss 6, Pp 1145-1156 (2018)

Carbon fiber-reinforced polymer material has been widely used in space/aerospace industries for manufacturing of spacecraft structures, satellite panels and antennas. In space, composites can be subjected to periodic thermal cycling (TC) in which tem

The effect of the percentage of steered plies on the bending-induced buckling performance of a variable stiffness composite cylinder

Autor: Rouhi Mohammad, Ghayoor Hossein, Hoa Suong V., Hojjati Mehdi

Publikováno v: Science and Engineering of Composite Materials, Vol 22, Iss 2, Pp 149-156 (2015)

The fiber steering capability of automated fiber placement machines offers the designers more room to fully exploit the directional properties of composite materials. Circumferential stiffness tailoring by fiber steering can considerably increase the
