“…Braided composites are known to have high specific energy absorption for tubular sections upon axial crushing when compared with metals [20]. The effect of braid angle upon energy absorption properties has been the focus of previous research which concluded that among 30 • , 45 • and 60 • braiding angles, 60 • is the braiding angle at which biaxially braided carbon fibre tubes exhibit highest specific energy absorption [21].…”

The increasing demands in subsea industry such as oil and gas, led to a rapidly growing need for the use of advanced, high performance, lightweight materials such as composite materials. E-glass fibre laminated pre-preg, filament wound and braided tubes were tested to destruction under hydrostatic external pressure in order to study their buckling and crushing behaviour. Different fibre architectures and wind angles were tested at a range of wall thicknesses highlighting the advantage that hoop reinforcement offers. The experimental results were compared with theoretical predictions obtained from classic laminate theory and finite element analysis (ABAQUS) based on the principal that the predominant failure mode was buckling. SEM analysis was further performed to investigate the resulting failure mechanisms, indicating that the failure mechanisms can be more complex with a variety of observed modes taking place such as fibre fracture, delamination and fibre-matrix interface failure.

“…The progressive crushing process which yields a higher energy absorption depends on the mechanical properties of the fibre and the resin, fibre and resin volume fractions, laminate stacking sequence, fibre orientation and the geometry of the tube [7,8]. However, for the same parameters, different levels of the specific energy absorption can be achieved by changing only the geometry of composite structures [9]. The effect of changing the dimensions on the energy absorption was studied in [10,11] for the circular and square composite tubes.…”

“…Studies by Mamalis et al [15,17] on conical shells showed that the specific energy absorption decreases as the semi-apical angle of the frusta increases. Many of the published data [8,9,[17][18][19][20][21] on the energy absorption of composite tubes utilized the circular and square cross sections. Furthermore, they all agreed that the geometrical shape is an important parameter which affects the energy absorption significantly.…”

This paper presents the quasi-static crushing performance of nine different geometrical shapes of small-scale composite tubes. The idea is to understand the effect of geometry, dimension and triggering mechanism on the progressive deformation of small-scale composite tubes. Different geometrical shapes of the composite tubes have been manufactured by hand lay-up technique using uni-directional E-glass fabric (with single and double plies) and polyester resin. Dedicated quasi-static tests (144 tests) have been conducted for all nine geometrical shapes with different t/D (thickness to diameter) ratios and two triggering profiles (45 ⁰ chamfering and tulip pattern with an included angle of 90 ⁰ ). From this unique study, it was found that the crushing characteristics and the corresponding energy absorption of the special geometrical shapes are better than the standard geometrical shapes such as square and hexagonal cross sections. Furthermore, the tulip triggering attributed to a lower peak crush load followed by a steady mean crush load compared to the 45 ⁰ chamfering triggering profile which resulted into a higher energy absorption in most of the geometrical shapes of the composite tubes.

“…The progressive crushing process which yields a higher energy absorption depends on the mechanical properties of the fibre and the resin, fibre and resin volume fractions, laminate stacking sequence, fibre orientation and the geometry of the tube [5,6]. However, different levels of specific energy absorption can be achieved by changing the geometry while keeping the same variables for the other parameters of the composite structures [7]. Hence, a suitable geometrical shape of the composite tubes which controls the progressive crushing process and maximizes the energy absorption has to be defined for the inner core structure of the proposed sacrificial cladding structure.…”

This paper focuses on the quasi-static crushing characteristics and the corresponding energy absorption of nine different shapes of small-scale composite tubes. The idea is to choose suitable cross sections and geometrical shapes of the composite tubes which can yield progressive deformation and higher energy absorption; the finalized geometrical shapes will be studied further for the inner core of a sacrificial cladding structure against blast loading. All the composite tubes have been manufactured by a hand lay-up technique using E-glass fabric and polyester resin. Quasi-static axial crushing tests have been conducted to understand the deformation patterns and the corresponding load-deformation characteristics of each composite tube. The effect of dimensions (thickness to diameter ratio) on the specific energy absorption of each composite tube was studied. Finally, the quasi-static test parameters such as the peak crush load, mean crush load and the specific energy absorption of all these composite tubes were compared. From this unique study, it was found that the specific energy absorption of special geometrical shapes (hourglass type -A, hourglass type -B, conical circular type -X and conical circular type -Y) of the composite tubes is significantly higher than the standard and uniform profiles such as the square and the hexagonal cross sections.
