Tool wear in turning of pure aluminum and drilling of carbon fiber reinforced plastics (CFRP)/titanium (Ti) stacks was investigated due to their importance in modern manufacturing. Although pure aluminum is a ductile metal while CFRP contains brittle carbon fibers, there exist also few important similarities which impact tool wear. For instance, neither work material contains inclusions harder ...

This paper offers a detailed, quantitative and exhaustive experimental comparison in terms of mechanical properties of three different layouts of carbon composite materials (CFRP) used to strengthen existing old timber beams highly affected by diverse natural defects and biological attacks, testing the use of pultruded laminate attached on the tension side of the element (LR), CFRP fabrics tota...

The interlaminar-toughened CFRP composite, T800H/3900-2, has interlaminar resin layers, whose thickness is about 20 mm. The interlaminar layer was evaluated quantitatively using an ultrasonic micro-spectrometer (UMSM) for the determination of the elastic constants, which is quite difficult by other techniques. At first, the composite was ground to remove the outermost CFRP layer, and the interl...

This work studied the grindability of the multidirectional carbon fibre-reinforced plastic (CFRP) composites with the panel layup of [(0◦/90◦/45◦/−45◦)3]s. Focuses were on the chip formation, material removal mechanism, ground surface features and grinding force characteristics. The results were systematically compared with the unidirectional CFRP composites. It was found that the grinding forc...

Toward the goal of delamination detection and quantification in laminated composites, this paper examines guided wave propagation and wave interaction with delamination damage in laminated carbon fiber reinforced polymer (CFRP) composites using frequency-wavenumber (f-k) analysis. Three-dimensional elastodynamic finite integration technique (EFIT) is used to acquire simulated time-space wavefie...

A cradle-to-grave life cycle assessment (LCA) of structural aircraft materials has been utilised to assess and compare the total emissions produced during manufacturing, use and disposal of aerospace materials and their selected components. First, a comparison of aluminium, GLARE and carbon fibre reinforced polymer (CFRP) plates was performed to investigate the potential of lightweight composit...

This paper describes a research program that was conducted in two phases to study the behavior of a high modulus CFRP system for strengthening steel structures. The first phase of the research consisted of an experimental program and finite element analysis to study the bond characteristics of the system. The findings indicate that a reverse tapered plate end detail can effectively increase the...
