Delamination Analysis of Carbon Fibre Reinforced Laminates: Evaluation of a Special Step Drill
Drilling of carbon fibre/epoxy laminates is usually carried out using standard drills. However, it is necessary to adapt the processes and/or tooling as the risk of delamination, or other damages, is high. These problems can affect mechanical properties of produced parts, therefore, lower reliability. Production of higher quality holes is a challenge to everyone related with composites industry...
متن کاملMachining of Fibre Reinforced Plastic Composite Materials
Fibre reinforced plastic composite materials are difficult to machine because of the anisotropy and inhomogeneity characterizing their microstructure and the abrasiveness of their reinforcement components. During machining, very rapid cutting tool wear development is experienced, and surface integrity damage is often produced in the machined parts. An accurate selection of the proper tool and m...
متن کاملDelamination Analysis in Composite Root of a Carbon-Layer Reinforced Wind Turbine Blade
The inconsistencies accompanied with material properties tipically cause the rise of delamination risk in composites made of different types of glass and crabon fibers. In this study, the delamination of a composite beam reinforced with a carbon layer under bending load is investigated. To this end, a small piece of a wind turbine blade root in the form of a heterogeneous laminated plate is sim...
متن کاملAssessment of the Exit Defects in Carbon Fibre-Reinforced Plastic Plates Caused by Drilling
This paper investigates the formation of the exit defects in carbon fibre-reinforced plates and characterizes their features in terms of drilling conditions. It was found that spalling and fuzzing are the major mechanisms of exit defects. The spalling, consisting of a main region and a secondary region, is caused by chisel and cutting edge actions, in which the former plays a key role. The fuzz...
متن کاملAntenna Patterns from Single Slots in Carbon Fibre Reinforced Plastic Waveguides
Slotted Waveguide Antenna Stiffened Structure (SWASS) is a type of conformal load-bearing antenna where top-hat cross-section stiffeners on skins, or blade stiffeners in sandwich panels, serve the dual purpose of acting both as structural stiffeners and as waveguides. Cutting slots through the outer skin and into these waveguide stiffeners creates slotted waveguide antenna arrays. Two of the ke...
