“…The growing use of composite tubes as support structures in transport and civil engineering work has increased the interest in stress analysis of cylindrical composite structures [1,2]. The growth in use is driven by the advantages offered by composite materials of high strength to weight ratio, high energy absorption, and the ability to be used in extreme conditions and high energy absorption during impact.…”

“…The result shows that the maximum impact force increases as the curvature increases. The crush behaviors and energy absorption of composite tubes have been investigated in references [2,11,[14][15][16][17][18][19]. From the results, we can find that the micro-structure and geometry have great influence on the impact damage and energy absorption.…”

The transverse impact performance of three dimensional (3-D) braided composite tubes has been studied both experimentally and numerically. Three types of braided composite tubes were manufactured by changing the number of braiding layers. The transverse impact test was performed on a modified split Hopkinson pressure bar (SHPB) apparatus under three impact gas pressures. From the tests, impact load, displacement and energy absorbed all increase with the increase of gas pressure. The increase of braiding layers leads to the increase of the impact load and energy absorption, but leads to the decrease of impact displacement. The specific load normalized by the linear density of the tubes also increases with the increment of braiding layers. The results indicated that more braiding layers contributed to higher stiffness. The impact damage modes were matrix crack, fiber breakage and shear bands at the area of impact. From the finite element method (FEM), the stress distribution on the impacted tube was highlighted plus the damage progression during the transverse impact cycles.

The objective of this work is to investigate yarn defects and specimen size on the impact compressive properties of 3-D angle interlock woven composites (AIWCs). The size effects on impact compressive properties were tested along in plane and out of plane directions. A new finite element model, with inherent defects in the geometrical model of yarns, was established to simulate impact compressive properties of the 3-D AIWCs. The model was further used to analyze size effects on impact compressive properties of 3-D AIWCs. We found the size effect on the 3-D AIWCs was not apparent both in experimental and numerical results; however, the random defects in yarns had a great effect on the compressive properties of 3-D AIWCs along different directions. The yarns effects will weaken the compressive stiffness and strength significantly.

This paper reports dynamic mechanical behaviors of 3-D rectangular braided composite with different braiding angles under multi-pulse impact load. The composite materials were prepared with braided preforms which have braiding angles of 15 °, 26° and 37 °, respectively. Impact compression tests were conducted in split Hopkinson pressure bar. High-speed camera system was used to capture damage growth process and a meso-scale finite element model was established to investigate failure mechanisms. We found that the braiding angle has significant effects on damage development, failure mechanisms and ultimate damage morphogenesis. The braided composite with 15° braiding angle shows a linear elastic response at the initial stage of stress–strain curves until the peak load. After the peak load, the composite has brittle failure behaviors, while the composites with 26° and 37° braiding angles exhibit non-linear elastic response at the beginning stage of stress–strain curves and ductile failure mode after yielding points. The composites with different braiding angles demonstrated both distinguished damage development and final fracture morphology. In addition, load-bearing ratio of yarns in composite was also affected by braiding angles.
