“…At the same time, there is also an increasing interest to substitute glass and carbon fibers by natural ones [14]. Natural fibers present some advantages when compared to their synthetic counterparts: they are cheaper, they have lower mass per unit area, they are eco-friendly, recyclable and biodegradable by nature, they do not produce skin irritation, and they provide good acoustic-insulating properties [15][16][17].…”

As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. The large wall thickness relative to the cell size of the jute-vinylester cores, which inhibits buckling, and the heterogeneities in the composite, which are preferential damage initiation sites, explain the observed behavior. When compared in terms of the specific strengths, the jute/vinylester cores introduced in this work show similar performances to those of their commercially available counterparts. The results from this study suggest that jute-reinforced cores have the potential to be an alternative to standard cores in applications that sustain compressive static loads.

“…It was also observed that the tensile strength of the composites was higher when the stronger material (jute) was used as the skin instead of wool felts and also with increasing content of jute fibers. Comparatively less fiber pullout was observed for the jute fibers suggesting better compatibility with the matrix . Further physical and chemical treatment of fibers was suggested to be necessary for improving the properties of the composites.…”

“…In a different approach than using natural cellulose fibers as reinforcement, wool felts and flax fibers were used to develop hybrid composites with epoxy resin. Layers of wool and/or jute felts were placed in different configurations and composites formed by curing the resin at room temperature . Figure shows an optical image of the microstructure of composites containing two layers of jute and wool felt in between.…”

Composites are primarily made using matrix and reinforcement as major components but may also contain several other fillers or additives. A majority of the composites are made using synthetic fibers and polymers. However, in the last few decades, focus has been on developing biocomposites using renewable resources. Conventionally, biocomposites are developed using natural fibers such as jute, Kenaf, or Ramie as reinforcement and synthetic resins such as polyethylene, polypropylene and epoxy as matrix. Typically, biocomposites contain either the reinforcement or matrix which makes the composites partially degradable. Such partially degradable composites provide good properties, but the presence of a nonbiodegradable component, particularly as a matrix limits their biodegradability. Alternatively, composites that contain both the matrix and reinforcement from renewable resources which make the composites completely degradable have also been developed. However, these completely biodegradablebiocomposites do not have the desired mechanical properties and stability at high humidities or in aqueous environments which restricts their application. In addition, natural fibers and resins used in biocomposites have inherent limitations and also not easily processable. To overcome limitation of using a single reinforcement or matrix derived from bioresources, hybrid composites that contain more than one reinforcement or matrix are developed. Such hybrid composites are manufactured by either intimately mixing two or more fibers or other reinforcing materials or by placing different layers of the reinforcement and molding them into composites using one or more resins. Conventionally, hybrid composites refer to metallic and ceramic based reinforcement, matrix and fillers. Although hybrid biocomposites are gaining significant attention, the presence of multiple reinforcements and/or matrix makes it difficult to process and also to predict the properties of such composites. Hence, understanding the properties and potential of using multiple reinforcements and/or matrix materials from renewable resources to develop biobased hybrid composites is highly desirable. This article discusses hybrid composites that contain a major proportion of renewable materials. Hybrid composites not only provide better properties but could also lead to substantial cost reduction due to the incorporation of inexpensive raw materials. These composites show potential for use in aeronautical, sporting goods, wind power turbine blades, helmets and civil construction such as pedestrian bridges and many other applications. This review provides an overview of the biobased materials used to develop hybrid composites, their processability and their potential applications. POLYM.

“…Moreover, difficult fillers dispersion in the matrix occurs because of higher fibre‐fibre interaction than fibre‐matrix one. Poor fibres distribution and weak fibre‐matrix interfaces results in low mechanical properties of the composites .…”

This work focused on the use of bio‐derived charge, in order to reduce the environmental impact of traditional oil‐based polymers (HDPE in this case). In fact, we introduced waste paper fibres and a starch‐derived polymer in Wood Plastic Composites (WPC). We produced different materials: 10 wt% of recycled paper fibres (10F), 30 wt% of wood flour (30W) and a mix of two fillers (30W10F). Polyethylene‐graft‐maleic anhydride (MAPE) has been introduced as compatibilizer and a NaOH immersion treatment on both cellulosic filler has been done in order to improve composites properties. A starch‐derived polymer was then added to the matrix to reduce HDPE amount (30W10F15S). Samples were produced through turbomixing followed by compression moulding technique, and then subjected to tensile tests, SEM analysis, water absorption tests and hardness tests (Shore D). Results evidenced a synergic effect of both cellulosic fillers, and the best results were obtained for 30 wt% wood, 10 wt% fibre of paper, and 3 wt% of MAPE, in which MAPE addition improved interfaces. Samples with starch‐derived polymers have shown typical blends morphologies, and cellulosic fillers treated with NAOH revealed an effective attack. The hardness measure displayed that the presence of cellulosic recycled fibres increased both superficial hardness of the composite and temperature resistance, while the presence of starch‐derived polymer and fibres treated with NaOH caused a higher softening effect.
