StrengthCompression After Impact (CAI) strength is critical to the safety and weight of carbon fibre aircraft. In this paper, the standard aerospace industry practice of using separate analyses and tests for panel buckling and CAI strength is challenged. Composite panels with a range of stacking ...

A compressive strength study of composite laminates after low velocity impact h as been conducted. The damaged area due to the low velocity impact is considere d as a circular inhomogeneity. The residual stiffness of the impacting damaged a rea is predicted by using finite element modeling and ex...
A simple approach to determine the compressive strength of composite sandwich structures after barely visible impact damage is presented. The damaged regio... WS Johnson,JE Masters,DW Wilson,... - 《Journal of Composites Technology & Research》 被引量: 36发表: 1996年 Compressive strength of honey...
To study low-speed impact properties and residual compressive strength of composite laminates,dropweight tests and compressive failure tests after impact were carried out. Acoustic emission technique was used to monitor damage initiation and propagation. Ultrasonic C-scan was used to determine the damage...
The first describes experiments and the second presents a model to accurately predict the compressive strength of concrete columns confined by composite materials. FRP is wrapped around concrete columns and RC columns to determine the difference between their behaviors under uniaxial compression. ...
Similar trend in the results were also found at 60 days where the compressive strength of FA mixes with CNTs remained higher than that of the reference FA mix without CNTs. The increment in compressive strength of fly ash cement composite with the additional carbon nanotubes agreed with ...
The design process at Zodiac Aerospace requires the ability to accurately predict the strength of a composite honeycomb core sandwich panel to adhere to strict FAA regulations. The most common failure mode in long beam composites is in compression. Following ASTM D7249 for a four-point bend test...
