“…[1][2][3] Interest in natural fiberreinforced polymer composites is growing annually and are used to reinforce plastics because of their key advantages, such as their environmental availability and biodegradability, cost-effectiveness, and low cost. 1,4,5 In Algeria, many natural fibers that constitute the key wealth in the country's nature can be valued in the domestic industry; quite a few papers talk about the use of these fibers as reinforcing agents in composites such as esparto, 6 date palm, 7 lygeum spartum. 8 More frequently, for the application of bio-sourced composite sheets, these fibers are combined with resins.…”

In this paper, low-velocity impact and compression after impact damage tolerance of composite reinforced with natural luffa mat were studied for the first time. The effect of impact energy and the influence of the damaged area on the residual mechanical properties under compression were investigated. Acoustic emission (AE), digital image correlation (DIC) and scanning electron microscopy (SEM) were used for the evolution of different damage modes and displacement fields. The findings of the experiments reveal that compression after impact tests of 1, 2, and 3J show a significant effect of the residual damage which decreases residual compressive strength by 12.61, 24.14, and 30.9%, respectively, compared to the unimpacted composite, but Young’s modulus was not significantly affected. Multivariable statistical analysis of the AE signals identified four classes of damage: matrix cracking, fiber-matrix debonding, delamination, and fiber failure. It also showed that the damage mode of unimpacted composites which presents the majority of the amplitude events of the AE signals is mainly due to fiber failure, by contrast, for impacted composites the damage mode is mainly due to fiber-matrix debonding. The AE results are convincing and they were confirmed by SEM images of the fractured faces of the specimens, which revealed the main causes of material failure during the compression after impact test. The DIC system monitored the effect of pre-existing damage under compressive loading and found that increasing impact energy increases the stress concentration around the impacted area and has a significant effect on residual crack development, much more in the loading direction.

“…Among the natural fibres, [11][12][13] the flax fibre is the most widely used, thanks to its good mechanical properties. [14][15][16] Therefore, many researchers have examined the behaviour of flax fibre-reinforced composites under single lowvelocity impacts.…”

This paper aims at studying the damage evolution of a [0/90]3S cross-ply flax/epoxy laminate repeatedly impacted at three energy levels of 5, 6 and 7J. Several specimen plates were prepared by the vacuum infusion technique and then subjected to repeated low velocity impacts. To assess external damage mechanisms in the impacted plates, an inspection of the back and front faces damage was conducted by using a high-resolution digital reflex camera. Moreover, different techniques were used to evaluate the internal damage such as intensive light exposure, infrared thermal imaging, and computed X-ray tomography. The obtained results show that damage is visible even at low energy level and starts to appear from the first impacts, especially in the back face of the flax/epoxy samples. In addition, after front and back faces cracks appear, delamination is the most predominant damage mechanism that occurs during the different phases of impact fatigue loading. Its size is found to extend with the energy level and the multiplication of impacts.

“…Djoudi et al [21] in their study related to the physical and mechanical characterizations of bio composite materials based on palm fibers, they have found that tensile strength tests of the bio composite material with different fiber percentages (04, 07, 10 and 15%) shows an improvement in the mechanical properties of the virgin resin proportional to the fiber mass ratio up to 10% while a degradation of these properties is detected for a fiber mass ratio of 15%.…”

Improving the mechanical and physical properties of bio-composite materials involves the incorporation of plant fibers such as Jute, Hemp, Kenaf, Ramie, Sisal, Linen, etc. The existence of Diss grass (Ampelodesmos mauritanicus) in abundance in the east of Algeria especially in Khenchela region and taking into account their mechanical resistance and their low density, which justifies their choice of use in composite materials. Tensile and hardness tests for different volume fractions (from 05% to 20%) of short fibers of Diss are performed. The increase in fiber content and their treatment improves the mechanical characteristics of the composite materials. These concentration levels are added to a Polyester resin matrix. Our work relates to the study of a composite material reinforced by a vegetable fiber of which different volume ratio of short Diss fiber are considered. The results collected are purely experimental.
