|Abstract: ||Carbon fibre-reinforced polymer (CFRP) textile composites are widely used in
aerospace, automotive and construction components and structures thanks to their relatively
low production costs, higher delamination and impact strength. They can also be used in
various products in sports industry. These products are usually exposed to different in-service
conditions such as large bending deformation and multiple impacts. Composite materials
usually demonstrate multiple modes of damage and fracture due to their heterogeneity and
microstructure, in contrast to more traditional homogeneous structural materials like metals
and alloys. Damage evolution affects both their in-service properties and performance that can
deteriorate with time.
These damage modes need adequate means of analysis and investigation, the major approaches
being experimental characterisation, numerical simulations and microtomography analysis.
This research deals with a deformation behaviour and damage in composite laminates linked to
their quasi-static bending. Experimental tests are carried out to characterise the behaviour of
woven CFRP material under large-deflection bending. Two-dimensional finite element (FE)
models are implemented in the commercial code Abaqus/Explicit to study the deformation
behaviour and damage in woven CFRP laminates. Multiple layers of bilinear cohesive-zone
elements are employed to model the onset and progression of inter-ply delamination process.
X-ray Micro-Computed Tomography (MicroCT) analysis is carried out to investigate internal
damage mechanisms such as cracking and delaminations. The obtained results of simulations
are in agreement with experimental data and MicroCT scans.|
