Simulation of edge impact and compression after edge impact in CFRP laminates

Composite Structures, 2020
Abstract This paper presents the application of a composite damage model to predict the edge impact and compression after edge impact (CAEI) response of CFRP laminates. First, a mesh sensitivity analysis is performed showing that the mesh needs to be sufficiently fine to accurately capture the permanent out-of-plane deformation at the impact location,

Compression After Impact Modeling of Damage Tolerant Composite Laminates

51st AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference<BR> 18th AIAA/ASME/AHS Adaptive Structures Conference<BR> 12th, 2010
An existing compression after impact (CAI) model was used as the fitness function in an optimization routine to produce a damage tolerance optimized composite layup. This laminate was tested in a CAI strength experiment, alongside a baseline quasi-isotropic layup.

Compression after impact behavior of titanium honeycomb sandwich structures

Journal of Sandwich Structures & Materials, 2017
Titanium honeycomb sandwich structures are gradually used in several newly developed aircrafts in China. During the manufacturing process and aircraft service life, low-velocity impacts from foreign objects (typically stones, tools and hails, etc.), would quite likely happen and could not be completely avoided.

Impact and compression-after-impact performance of weft-knitted glass textile composites

Composites Part A: Applied Science and Manufacturing, 2005
Abstract This research dealt with the impact resistance and tolerance of composite materials manufactured from weft-knitted E-glass fabrics. Three different styles of the weft-knit structures, Milano, 1×1 rib and plain knit, were investigated together with two further variations of Milano and rib structure and one variation of plain knit.

Low velocity impact and compression after impact simulation of thin ply laminates

Composites Part A: Applied Science and Manufacturing, 2018
Abstract Numerical simulations can help in the understanding of the damage sequence of polymer based composite laminates during an impact event, which is a difficult experimental task when dealing with a large number of plies. Low velocity impact and compression after impact in thin ply fabric laminates are studied through numerical simulations in ...

COMPRESSION AFTER IMPACT STRENGTH OF A BUCKLING RESISTANT TOW STEERED PANEL [PDF]

, 2013
Optimised, steered fibre laminates, manufactured using Continuous Tow Shearing have regions of high stress. The effect on residual compressive strength of impact to these regions is investigated.

Compressive Failure of Unbalanced Sandwich Composites After Impact Loading

Recent Advances in Structural Mechanics, 1994
Abstract An unbalanced sandwich composite structure consisting of titanium and glass reinforced plastic (GRP) facesheets with a phenolic honeycomb core is considered for construction of a surface ship mast. Areas of concern in using the unbalanced sandwich composite structure in the load-bearing application are the response due to ...

Modelling damage growth in composites subjected to impact and compression after impact

Composite Structures, 2017
Abstract Compression After Impact (CAI) tests are frequently performed to characterize the effect of impact damage on strength of composites. This paper presents an integrated single finite element model that enables analysis of impact damage and CAI without major simplifications and idealizations of damage in composites.

Certification Cost Reduction Using Compression-After-Impact Testing

2001
An approach to reduce certification development cost can be accomplished by testing the important strength allowables that make up the primary design drivers. Through a process referred to as a “modified building block approach,” these primary design drivers are weighted and selected based on criticality.
