Effect of fibre volume fraction on energy absorption capabilities of E-glass/polyester automotive crash structures

Stabilization of the Numerical Priming to Stabilization Phenomenon in the Crushing of a Composite Panel Using Local and Diffuse Damage Laws

“…In parallel with these local effects, it can be noticed that drops down and increase of resisting forces after the peak force and in the mean force plateau, are conditioned by the capacity of the plies to continuously transmit the loading in the height of the structure (distance to the obstacle) or to break the loading path through local buckling kink band formation and ruptures (confined plies) or outward global buckling of plies [20]. This phenomenon has been identified by Lavoie [21] whose fundamental work shows that the plateau value and the oscillations around the mean value for APC2 laminates is twice that of CFRP or GR-Kv epoxy laminates.…”

“…The link between the frequency of the mean force oscillations in the plateau region and the width of the kink band can be due to the relative value of the interlaminar strength and the longitudinal strength and critical value of strength in compression of laminates [22]. The more the fiber proportion, the higher the SEA and the amplitude of the mean force in the plateau region [20]. As for the case of the influence of the structure profile, these result must be put into perspective with the kind of fibers [23].…”

Effect of Glass Fibers Stacking Sequence on the Mechanical Properties of Glass Fiber/Polyester Composites

“…Moreover, glass fibers are actually used as short strand or longitudinal plain woven fibers to polymer matrix composites. This enables the fibers to be used in many applications and products such as hot pipes, water tanks, wind turbine blade and in the field of aerospace due to their good mechanical and impact properties [7][8][9].…”

“…Most of the recent research studies focused on the mechanical and impact properties of the continuous plain woven glass fiber reinforced polymer composites [7][8][9][10]. Moreover, the effect of the impactor shape and water immersion aging on the drop-weight impact responses of carbon reinforced epoxy and hybrid glass-graphite fibers/toughened epoxy composites has been investigated [11][12][13].…”

Can Plant-Based Natural Flax Replace Basalt and E-Glass for Fiber-Reinforced Polymer Tubular Energy Absorbers? A Comparative Study on Quasi-Static Axial Crushing

“…Energy absorption of structures made of composite materials relate to safety in automotive engineering because crashworthiness relates to energy absorption through controlled failure modes that enable the maintenance of a gradual decay in the load profile during energy absorption (Wang et al, 2016). In literature, the effects of different parameters on the crashworthiness behavior and energy absorption capabilities of composite energy absorbers were investigated, i.e., Zhou et al (2015) investigated the crashworthiness characteristics of carbon fiber-reinforced dualphase epoxy-polyurea hybrid matrix composites, Mozafari et al (2018) considered double-sided corrugated tubes under axial crushing, and Esnaola et al (2016) investigated the effect of fiber volume fraction on E-glass/polyester crash structures. To improve energy absorption efficiency of crushable energy absorbers made of composite tubular structures, different foamfiller materials, such as cork core (Sanchez-Saez et al, 2011;Niknejad et al, 2016), aluminum (Fischer, 2016), polyurethane (Yan et al, 2014b), etc., have been used.…”
