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.

In recent days, natural fibers are extremely influential in numerous applications such as automobile body building, boat construction, civil structure, and packing goods. Intensification of the properties of natural fibers is achieved by blending different natural fibers with resin in a proper mixing ratio. This investigation aims to synthesize a hybrid polymer matrix composite with the use of natural fibers of flax and loops of hemp in the epoxy matrix. The synthesized composites were characterized in terms of tribological and mechanical properties. The Taguchi L16 orthogonal array is employed in the preparation of composite samples as well as analysis and optimization of the synthesis parameters. The optimization of compression molding process parameters has enhanced the results of this investigation. The parameters chosen are percentage of reinforcement (20%, 30%, 40%, and 50%), molding temperature (150 °C, 160 °C, 170 °C, and 180 °C), molding pressure (1 MPa, 2 MPa, 3 MPa, and 4 MPa), and curing time (20 min, 25 min, 30 min, and 35 min). From the analysis, it was observed that the percentage of reinforcement is contributing more to altering the fatigue strength, and the curing time is influenced in the impact and wear analysis.

This investigation focuses on studying the properties of treated and untreated Musa acuminate peduncle fiber (MAPF)‐reinforced epoxy composites. The effect of fiber weight fraction and alkali treatment on the mechanical, thermal, and morphological characteristics of MAPF‐reinforced epoxy composites was investigated for the first time. A considerable enhancement in the tensile, impact, and flexural characteristics was observed at 20 wt% fiber; beyond 20 wt%, the properties were found to decrease. The increase in cellulose (from 66.43 to 74.22 wt%) and decrease in lignin (from 16.85 to 7.91 wt%) and hemicellulose (from 13.72 to 8.58 wt%) in alkali‐treated fiber resulted in a more crystalline structure. This led to improved tensile (tensile strength 53.61 MPa and tensile modulus 0.561 GPa), flexural (flexural strength 64.33 MPa and flexural modulus 5.43 GPa), and impact (90.33 J/m) composite properties compared to the untreated fiber composite. After tensile testing, the composite's fractured cross‐sections were investigated using scanning electron microscopy, which revealed that the alkali‐treated MAPF‐reinforced composite had fewer voids and improved fiber bonding. Thermogravimetric analysis, Fourier transform infrared spectroscopy, and atomic force microscopy studies also revealed that alkali‐treated MAPFs area promising reinforcement for the epoxy polymer matrix.
