“…The previously described Property Prediction Model, was developed to predict a property of a series of particulate composites materials as a function of fiber content, when two experimental points of this property are given 31 . Here, we apply this model to the series of composites made using LC of the mentioned various densities and surprisingly—because these are not particulate composites, but made using continuous fibers—the curve fit is good enough and the prediction error was low (between 3.2% and 7.2%) (Figure 7).…”

“…The governing equation of the model is a second order polynomial equation containing two parameters κ and λ , which are related to the degrees of adhesion and the degree of dispersion of the particles in the matrix, taking into account the property each time examined. The model was found to be able to accurately predict a number of properties, in the case of a composite series, when only two experimental points in that series are known 31 …”

Natural fiber (NF)‐reinforced thermosetting composites exhibit excellent properties but, due to the usually hygroscopic nature of the fibers, these composites may suffer from the effects of moisture absorption. Luffa cylindrica is a NF, potentially useful in the manufacture of composite materials, but it is highly hygroscopic. A technology is developed for the fabrication of moisture‐resistant L. cylindrica‐reinforced epoxy composites and the various parameters that affect the process are investigated using long‐term moisture absorption experiments and dynamic mechanical analysis of dry and moist specimens. The technology concludes to a L. cylindrica‐reinforced bilayer matrix made of a first linseed oil‐modified precured epoxy and a final unmodified epoxy layer. This composite offers a reduced water absorbance by 33% and an almost identical Tg compared to the non‐modified epoxy reinforced with L. cylindrica. The same technology is used to manufacture water‐resistant L. cylindrica‐reinforced composites from both, environmentally friendly, matrix and reinforcement.

“…In another study, Papanicolaou et al [ 63 ] developed an environmentally friendly epoxy adhesive using dry olive pit powder with 0 to 3.5 wt.% of filler content. A mill was used to transform the olive pits into fine powder, reaching a maximum particle diameter of 5 µm.…”

Olive Stones as Filler for Polymer-Based Composites: A Review

Olives’ consumption produces copious agricultural byproducts that have accompanied humanity for millennia, but the increasing worldwide production complicates its management. Most wastes are generated during olive oil production in form of olive stones and other lignocellulosic derivatives. Industrial processes of chemical or physical nature to recover economically compounds from biomass residues are costly, difficult, and non-environmentally friendly. Cellulose, hemicellulose, and lignin biopolymers are the principal components of olive stones, which present interesting qualities as lignocellulosic fillers in polymeric composites. This review will summarize examples of composites based on thermoplastic polymers, such as polystyrene (PS), polylactide (PLA), polyvinyl chloride (PVC), polypropylene (PP), and polycaprolactone (PCL); thermosetting resins (phenol-formaldehyde, unsaturated polyesters, and epoxy) and acrylonitrile butadiene rubber/devulcanized waste rubber (NBR/DWR) blends focusing on the fabrication procedures, characterization, and possible applications. Finally, thanks to the wide disparity in polymer matrix types, the variability in applications is important, from adsorption to mechanical enhancement, showing the easiness and benefit of olive stone integration in many materials.

“…Epoxy adhesive has high bonding strength and versatility, was once called the "universal adhesive", and has been widely used in aerospace engineering, shipbuilding, the chemical industry, electronics and other elds. [1][2][3][4] But the cured epoxy resin has the disadvantages of high brittleness, low fracture energy and poor impact resistance, [5][6][7] which has limited its application in engineering. It is therefore of great interest to improve the fracture toughness of epoxy.…”
