Energy absorption capability and bending collapse behavior of an aluminum (Al)/carbon fiber reinforced plastic (CFRP) short square hollow section (SHS) beam were investigated under transverse quasi-static loading. The Al SHS beam was reinforced by CFRP, and the specimen was co-cured via an autoclave curing process. Three-point bending test was performed with five different lay-up sequences and three different laminate thicknesses. Stable bending collapse accompanying plastic hinge was observed in all specimens. Individual bending collapse behaviors were different depending on the lay-up sequences. The specific energy absorbed (SEA) was improved by up to 29.6% in the Al/CFRP SHS beam specimen with a [0/+45°/90°/−45°]n lay-up sequence and laminate thickness of 1.168 mm (thickness ratio of Al: CFRP = 1: 0.87, 8 plies of prepreg) compared to the Al SHS beam. The SEA was not related with damage area of the Al/CFRP SHS beam. Finite element analysis and theoretical analysis based on Kecman’s model were performed to investigate the effect of reinforcement by CFRP on the Al SHS beam.read more

Energy absorption of metal, composite and metal/composite hybrid structures under oblique crushing loading
TL;DR: In this paper, the authors explored crashworthiness characteristics of aluminum/carbon fiber reinforced plastic (CFRP) hybrid tubes, experimentally and numerically, subjected to three different loading angles by comparing with aluminum alone and CFRP alone tubes, in which the deformation patterns and several key indicators related to the crashworthiness of these structures were assessed.

Delamination fracture of multidirectional carbon-fiber/epoxy composites under Mode I, Mode II and Mixed-Mode I/II loading
TL;DR: In this paper, the authors considered the variation of the interlaminar failure energy, GC, with the extent of crack jumping, and ensuing fiber bridging, which arises during the growth of the delamination in the multidirectional-laminates under the various modes of loading.
