“…Because they weigh less and have lower dermal abrasion, require less processing energy, have better vibration‐dampening properties, and are more insulating and sound‐absorbing than petroleum‐based or synthetic fibers, flax fibers are a desirable option for use as reinforcing agents in advanced polymer matrix composite materials 10,11 . The flax plant's stems reach a height of between 80 and 120 cm.…”

Due to their many benefits, including their environmentally benign nature, low cost, biodegradability, and generally good mechanical behavior, natural fibers represent one of the most attractive reinforcing materials. This paper describes the fabrication of green composites based on waste polyethylene (WPE)/bagasse reinforced with flax and sisal fibers. The composites were prepared using the hot‐mixing method in an internal mixer and molded in a hot press with a suitable thickness. This thickness is about 6 mm to ready for measurements belonging to the wood as impact strength, flexural strength, hardness, water absorption, density, and porosity measurements. The prepared specimens will be subjected to gamma irradiation to evaluate the effect of ionizing radiation on the fabricated samples. Furthermore, the thermal behaviors of the fabricated specimens were examined using TGA and DSC techniques. As a result of their superior mechanical performance, sisal, and flax fibers reinforced WPE/bagasse were able to create composites that were suitable for use in wood applications. The mechanical results revealed that composites with flax fiber are superior to composites with sisal fiber. With 30 phr fiber loading, WPE/bagasse thermal stability improved, with composites made of sisal being the best. With increasing fiber loading, the porosity of the composite rises due to the increase in density. Porosity decreases in composites with irradiation due to crosslinking and enhancement of the compatibility between fiber and matrix. Flax composites that have been irradiated exhibit significantly higher thermal stability than those that have not.Highlights Different advantages of natural fibers as their low cost, biodegradability, and generally good mechanical behavior are considered one of the most attractive reinforcing materials. Sisal and flax fibers reinforced WPE/bagasse were able to create composites that were suitable for use in wood applications. Green composites were prepared by the hot‐mixing method in an internal mixer and molded in a hot press with a suitable thickness of about 6 mm to ready for measurements belonging to the wood. Various studied properties were improved via ionizing irradiation due to crosslinking induced in the polymer matrix.

This study evaluates the sliding wear behavior of hybrid composites made of epoxy reinforced with alternating layers of flax fiber mats and steel wire mesh. The aim is to enhance the wear resistance of flax fiber‐epoxy composites by incorporating steel wire mesh. Specifically, three composite types are produced by varying their stacking sequences using the simple hand layup technique. Dry sliding wear tests are performed on a pin‐on‐disc test rig under different conditions according to ASTM G99 standard. Taguchi analysis is performed using an L25 orthogonal array and it reveals that sliding velocity is the most critical factor, followed by normal load, in affecting the wear rate of the steel‐flax‐epoxy hybrid composite. Subsequently, a steady‐state wear analysis shows that sliding velocity and normal load increase the specific wear rate (SWR), while steel reinforcement decreases it. ANOVA results indicate that sliding velocity significantly impacts wear rates to the extent of 69.47% for flax‐epoxy composite and more than 70% for flax‐steel‐epoxy composites. Additionally, electron microscopy is used to study the worn surfaces of the composites to determine the wear mechanisms.Highlights Successful fabrication of flax‐steel wire mesh reinforced hybrid composites. Wear behavior of multi‐layer composites with different stacking sequence. Use of statistical technique for the prediction of wear rate. Wear mechanisms are identified using electron microscopy.
