Effect of winding angle on the quasi-static crushing behaviour of thin-walled carbon fibre-reinforced polymer tubes

Abstract

Carbon fibre-reinforced polymer (CFRP) tubes have been increasingly used in various structural applications due to its lightweight and attractive crashworthiness performance. The key parameter of the winding angle plays an important role in the energy-absorbing performance of CFRP tubes. In order to understand the relationship between the compressive performance and winding angle, this article is aimed to study the effect of winding angle with ±45°, ±60° and ±75° of CFRP tubes. The thin-walled CFRP tubes were performed by the quasi-static compression test, which were fabricated using the wet winding technique. The result was concluded that as the winding angle increased, the compressive modulus showed the decreasing trend. In the view of energy absorption (EA) and specific energy absorption (SEA), it was exhibited the decreasing trend as the winding angle increased. It was noted that CFRP tubes with ±45° winding angle recorded the average maximum SEA of 24.67 kJ kg−1. Moreover, the crushing behaviour of thin-walled CFRP tubes were involved and studied.

Effect of infill pattern, density and material type of 3D printed cubic structure under quasi-static loading

“…Based on the related studies on crushing behaviour in the previous literature, 2,40,41 several parameters were used to quantify the crushing response of 3D cubic structures under the quasi-static compression test, such as peak load ( F peak ), mean crushing load ( F mean ), crushing load efficiency ( CFE ), energy absorption ( EA ) and specific energy absorption ( SEA ), respectively. Energy absorption ( EA ) represents the total energy absorbed during the quasi-static compression test, which is calculated as:…”

“…The excellent energy-absorbing characteristics and crashworthiness performance of lightweight structures have forced the design engineers to use them in many engineering applications, such as automotive, aerospace, marine and defence technology etc. 1–4 The weight reduction of lightweight structure is generally attained using the periodic cellular core structure 5 and various foams. 6–9 Nowadays, numerous research studies have investigated the mechanical properties of cellular structure, foam-core and hybrid materials.…”

Mechanical performance of composite flat specimens and pressure vessels produced by carbon/epoxy towpreg dry winding

“…Literature review revealed that there are extensive numbers of studies investigating influences of parameters on the performance of tubular structures, [1][2][3][4][5][6][7][8][9][10][11] including mechanical testing and characterization [12][13][14][15][16] aspects of traditional "wet filament winding" technique. For instance, in their very comprehensive studies, Cohen et al 5,6 focused on the influences of especially winding tension, laminate stacking sequence, and winding time.…”

An experimental investigation on lateral crushing response of glass/carbon intraply hybrid filament wound composite pipes

“…It was stated that the existence of delamination which depends on size, at the interface of adjacent layers resulted with reduction in stiffness values of pipes. In the literature, numerous studies have been devoted to the crashworthiness of composite materials [28][29][30]. However, despite the importance of the crushing response of the structure under low-velocity lateral impact for passenger safety in various passenger vehicles [31], most of these studies have mainly focused on crushing properties under axial compression load [32][33][34][35], and the limited number of studies has been carried out on the lateral crush response of polymer-based composite materials.…”
