Abstract A low velocity impact study of aircraft tire rubber on 3D textile-reinforced composite plates was performed experimentally and numerically. In contrast to regular unidirectional composite laminates, no delaminations occur in such a 3D textile composite. Yarn decohesions, matrix cracks and yarn ruptures have been identified as the major damage mechanisms under impact load. An increase in the number of 3D warp yarns is proposed to improve the impact damage resistance. The characteristic of a rubber impact is the high amount of elastic energy stored in the impactor during impact, which was more than 90% of the initial kinetic energy. This large geometrical deformation of the rubber during impact leads to a less localised loading of the target structure and poses great challenges for the numerical modelling. A hyperelastic Mooney-Rivlin constitutive law was used in Abaqus/Explicit based on a step-by-step validation with static rubber compression tests and low velocity impact tests on aluminium plates. Simulation models of the textile weave were developed on the meso-and macro-scale. The final correlation between impact simulation results on 3D textile-reinforced composite plates and impact test data was promising, highlighting the potential of such numerical simulation tools.

Experimental and numerical investigations of low energy/velocity impact damage generated in 3D woven composite with polymer matrix

“…The observed damage mechanisms in 3D woven composites are very different from those encountered in classical laminates due to the specific architecture of such materials. Due to the complexity of the encountered damage mechanisms, only very few impact modelling studies [18] can be found in the literature and are dedicated to very specific architectures.…”

Research Progress on Mechanical Properties Of 3D Braided Composites

“…These features lead to the application of complex shaped braided composite structures in impact protection areas, such as debris impact protection of supersonic aircraft and spaceship. Heimbs et al [28] developed the meso and macro-scale to study elastic energy stored during impact. Elias et al [29] presented the ODM-PMC model to investigate damage mechanisms of 3D woven composites and estimated the residual properties of the material.…”

Experimental investigations and variability considerations on 3D interlock textile composites used in low velocity soft impact loading

“…Thus, the higher the ratio of 3D warp yarns to straight warp yarns is, the higher the impact resistance is. However, a reinforcement with a high amount of undulated yarns has reduced in-plane properties [14]. Therefore, the reinforcement with 55% 3D warp yarns seems to offer a good compromise between impact damage tolerance and good stiffness properties.…”

“…This work follows on an investigation performed within a national research project on vulnerability of composite structures, which partly addressed the impact performance of different 3-D interlock carbon woven composites. The investigation which was both experimental and numerical [13][14][15] showed that the major damage mechanisms were yarn decohesion, matrix cracks and a few yarn ruptures mainly located at the back side of the composite plate. Three different reinforcement types with different ratios of 3D warp yarns to straight warp yarns (30%, 55% and 100%) were tested [14].…”

Results showed that for the same impact energy, damage decreases with an increasing ratio of 3D warp yarns.…”
