“…The primary reinforcement used is flax fiber, known as Amplitex 5042, supplied by Bcomp Ltd., Fribourg, Switzerland. The reinforcement is a woven fabric in a balanced 3 of 20 4 × 4 twill weave architecture with yarn of 500 tex having no twist and areal density of 500 g/m 2 [43]. The glass fiber, Interglas FK144 supplied by Porcher Industries GmbH, Erbach, Germany, is chosen as the secondary reinforcement material.…”

“…In this context, bio-composites derived from biofibers and biopolymers have gathered significant attention as they can provide necessary properties and functionalities at reasonable costs [2]. These bio-composites have become the focus of extensive research due to their specific properties, sustainable sourcing, biodegradability, low density, and cost-effectiveness [3,4]. Consequently, they are being applied as engineering materials in various fields, such as automotive, construction, packaging, and sporting goods, serving as a sustainable alternative to fiberglass composites in structural applications [5].…”

Increasing global concerns regarding environmental issues have driven significant advancements in the development of bio-based fiber reinforced polymer composites. Despite extensive research on bio-composites, there remains a noticeable gap in studies specifically addressing the challenges of repairing bio-composites for circular economy adoption. Traditional repair techniques for impacted composites, such as patching or scarf methods, are not only time-consuming but also require highly skilled personnel. This paper aims to highlight cost-effective repair strategies for the restoration of damaged composites, featuring flax fiber as the primary reinforcement material and distinct matrix systems, namely bio-based epoxy and bio-based vitrimer matrix. Glass fiber was used as a secondary material to validate the bio-based vitrimer matrix. The damage caused specifically by low impact is detrimental to the structural integrity of the composites. Therefore, the impact resistance of the two composite materials is evaluated using instrumented drop tower tests at various energy levels, while thermography observations are employed to assess damage evolution. Two distinct repair approaches were studied: the resin infiltration repair method, employing bio-based epoxy, and the reconsolidation (self-healing) repair method, utilizing the bio-based vitrimer matrix. The efficiency of these repair methods was assessed through active thermography and compression after impact tests. The repair outcomes demonstrate successful restoration and the maintenance of ultimate strength at an efficiency of 90% for the re-infiltration repair method and 92% for the reconsolidation repair method.

“…The study of surface free energy of all kinds of fibers takes on a new context. Depending on the application, the modification of surface tension can be used to improve moisture removal from the skin layers [ 1 ] and prevent the harmful effects of global warming by condensing water from the air in dry areas [ 2 ] or in the production of biocomposites [ 3 ]. For this reason, linen and hemp fibers are becoming more and more popular.…”

The article presents the exploration of flax and hemp fibers’ surface free energy depending on the chemical composition of the fiber, which is closely related to the plant variety and the method of extracting the fiber. For this purpose, tests of the surface free energy (SFE), evaluation of the percentage content of individual fiber components and FTIR analyses were conducted. The research was carried out with the use of fibrous materials prepared in three different ways: 1. To analyze the effect of subsequent stages of flax fibers refining process on chemical composition and SFE, 2. to explore the dependence of fiber SFE on hemp variety, the water-retting hemp fibers were used, 3. To evaluate the influence of the retting method of hemp fibers BIAŁOBRZESKIE variety on SFE, the fibers extracted with the use of dew and water retting were used as the research material. The study confirmed that the content of individual components in the fiber influenced its sorption capacity and therefore determined its hydrophilic properties. The values of Pearson’s linear correlation coefficients determined in the statistical analysis proved that the surface free energy was strongly correlated with the content of individual components in the fibers. Understanding the wettability characteristics of bast fibers will allow modeling the properties of products made of these fibers and designing surface modification processes in order to obtain specific functionality of textile products, depending on their intended utilization.

“…1 The current work combines two separate techniques of wood modification i.e., lumen filling (chemical modification) and densification (mechanical modification) to produce the advanced bio-products in a single step of in situ polymerization and densification. 54 To the best of our knowledge, this method of combining the densification with the chemical modification using biobased polymer (polylactic acid) has not been reported. This technique is an environmentally friendly and effective method to enhance wood performance.…”
