Lightweight materials and structures have attracted tremendous interests for their compelling
advantages in a range of engineering problems that have placed heightened requirements …

Braiding is an advanced textile manufacturing method that is used to produce two-
dimensional and three-dimensional components. Unlike laminated structures, braids have …

To improve the impact behaviour of composite laminates and to reduce the problem of the
complex damages after dynamic loads, a two-component commercial epoxy resin was …

The aim of this paper is to explore a novel bumper system consisting of a negative Poisson's
ratio (NPR) beam and a NPR absorber. The NPR beam is designed to improve the frontal …

This paper investigates the energy-absorbing characteristics of composite tube reinforced
PVC foam cores for use in lightweight impact-resistant sandwich structures. Compression …

In this work, the acoustic emission (AE) signals collected during the torsional tests of the 3D
braiding composite shafts were clustered using the principal component analysis (PCA) and …

The capability of a structure to absorb enormous amount of energy is a crucial issue,
particularly for structural components of vehicles, in decreasing the injury in case of collision …

Abstract Three-dimensional (3D) six-directional braided carbon/epoxy composites are
widely used in aerospace field and this is successfully fabricated in this study. The …

In the present study, the effect of adding various percentage (0.1, 0.3, 0.5, and 0.9 wt.%) of
carbon nanotubes on the impact properties of hybrid composites reinforced with the different …

This paper presents the impact shear fracture mechanisms of 3D braided composite
observed from computed tomography (CT) and the comparisons with finite element analyses …
