In this study, several hybrid CFRP laminates of different material and geometrical configurations have been subjected to impact by a high velocity steel sphere with an impact energy of c.a. 440 J.
Supposing the shell being assembled as a composite laminate, we show how the anisotropy of the material can influence the multistable behaviour and the robustness of stable configurations.
For both plywood and the paper laminate, the cross-linking reaction is carried out with sheets of the material pressed and heated in large laminating presses.
Furthermore, a scaling relationship is proposed to estimate kink-band toughness for other laminate configurations of the same material.
The cracking process for any other laminate made of the same material may be predicted by the suggested method.
Continuing work by Atraverda on the production of a composite-laminate form of the Ebonex® material, that can be cheaply formulated and manufactured to form substrate plates for bipolar lead acid batteries, is described.
The behavior and characteristics of classical membrane theory of isotropic materials are different from that of anisotropic materials, care must be taken to prevent secondary bending moments due to the unbalanced arrangement of laminates of anisotropic materials.
Curved laminates of composite materials are analytically investigated in this paper.
An unprocessed board is a laminate of a conductive material and an insulating dielectric substrate.
A theory is formulated for the small amplitude free vibration of thick, circular cylindrical shells laminated of bimodulus composite materials, which have different elastic properties depending upon whether the fiber-direction strain is tensile or compressive.
