A micromechanical model for the analysis of Z-fiber reinforcement

Manufacturing and low-velocity impact characterization of foam filled 3-D integrated core sandwich composites with hybrid face sheets

“…One of the concepts is truss reinforced core [21][22][23] and the other is an integrated hollow core in which the face sheet and core are integrated together in one construction, which is a byproduct of advances in textile/perform technology [24]. The fiber perform in integrated core sandwich is threedimensional and consists of two bi-directional woven E-glass fabric surfaces, which are mechanically connected with vertical woven ply.…”

“…Hollow core sandwich composite construction is a newly developed concept [21][22][23][24][25]. One of the concepts is truss reinforced core [21][22][23] and the other is an integrated hollow core in which the face sheet and core are integrated together in one construction, which is a byproduct of advances in textile/perform technology [24].…”

Effect of temperature on stresses and delamination failure of z-pinned joints

“…smalldiameter cylindrical rods embedded in the composite material and oriented perpendicular or at an angle to the layer interface, represent a possible method of arresting these cracks. Extensive studies that illustrated beneficial effects of z-pins on various aspects of the behavior of composite structures have been published by Freitas et al [1], Barrett [2], Lin and Chan [3], Palazotto et al [4], Vaidya et al [5] and Mabson and Deobald [6]. In particular, this method may be effective in enhancing fracture and fatigue resistance of co-cured joints between composite skin and stiffeners similar to the joint depicted in Fig.…”

“…One of the concepts is truss reinforced core [21][22][23] and the other is an integrated hollow core in which the face sheet and core are integrated together in one construction, which is a byproduct of advances in textile/perform technology [24]. The hollow region can provide space for fuel storage, a means to route wires, embed electronic assemblies etc.…”
