Abstract
This paper conducted high-speed impact tests for the carbon fiber resin matrix composite laminates toughened by multi-walled carbon nanotubes (MWCNTs) interlayers. Numerical simulations were conducted based on the tests by using the cohesive model with rate sensitivity and CNT toughening mechanism. It shows that the FEM (Finite element method) model can effectively predict the impact behavior of CNTs interlaminar toughened composites under high-speed impact. The influence and mechanism of CNTs on materials under impact were revealed, and it was found that the addition of CNTs can help materials resist delamination during impact and ensure the integrity of the laminate structure.
期刊介绍:
Polymer Testing focuses on the testing, analysis and characterization of polymer materials, including both synthetic and natural or biobased polymers. Novel testing methods and the testing of novel polymeric materials in bulk, solution and dispersion is covered. In addition, we welcome the submission of the testing of polymeric materials for a wide range of applications and industrial products as well as nanoscale characterization.
The scope includes but is not limited to the following main topics:
Novel testing methods and Chemical analysis
• mechanical, thermal, electrical, chemical, imaging, spectroscopy, scattering and rheology
Physical properties and behaviour of novel polymer systems
• nanoscale properties, morphology, transport properties
Degradation and recycling of polymeric materials when combined with novel testing or characterization methods
• degradation, biodegradation, ageing and fire retardancy
Modelling and Simulation work will be only considered when it is linked to new or previously published experimental results.
