Post-impact crush of hybrid braided composite tubes

The effect of lateral impact simulating prior damage, on the progressive crush characteristics of 2D-braided composite tubes is investigated. The emphasis of the investigation is on hybridization through the combined use of carbon, glass and/or aramid yarns, as well as through changes in braid yarn...

Description
Summary:The effect of lateral impact simulating prior damage, on the progressive crush characteristics of 2D-braided composite tubes is investigated. The emphasis of the investigation is on hybridization through the combined use of carbon, glass and/or aramid yarns, as well as through changes in braid yarn yield, and the use of different braid patterns. It is shown that the use of hybrids can lead to significant enhancement of crash-worthiness, and to the development of stable and well-defined damage mechanisms and their influence on characteristics of crush response.
