“…However, the curve smoothness increases with increasing filler rate, where 80–90 sample represents almost a linear EMSE curve. The increasing curve smoothness can be related to the structure’s increasing electrical conductivity and homogeneity, 51 since increasing filler ratio and slurry volume enlarge the amount of CFs and Al flakes. Therefore, the number of contact points and the width of the contact region increase between the conductive fillers in the composite paper.…”

Recycling every viable material to produce new value-added products not only reduces waste, but also provides an opportunity to create sustainable and innovative solutions while preserving our natural resources. With this motivation, electrically conductive one-dimensional carbon fibers and two-dimensional aluminum flakes reinforced cellulose matrix composite papers were manufactured using recycled materials with a scalable, eco-friendly, and low-cost papermaking process. The designed composite paper showed 36.1 dB electromagnetic interference shielding efficiency (EMSE) with an absorbance-dominated performance by absorbing 98.85% of electromagnetic waves. An efficient impedance matching was obtained on the composite paper surface using reinforcements with different morphologies. Cellulose paper samples were converted to electrically conductive composites (0.415 S/cm), and the electrical conductivity was altered by tailoring the reinforcement ratios. Thermo-mechanical test results revealed that the cellulose matrix’s storage modulus was increased from 1.44 to 2.1 GPa with a 46.5% improvement. The composite cellulose paper represented increased hydrophilicity with higher porosity. The environmentally friendly composite paper responses to the escalating environmental worries and possesses a tremendous possibility of being utilized as an electromagnetic shielding material.

“…Thus, the interface stress relaxation was reduced [ 32 , 33 ]. Therefore, a higher crystallinity usually indicated a higher stress transfer efficiency [ 34 , 35 , 36 ]. This also explained the much higher tensile strength of C−8008 compared to the other composites.…”

To investigate the influence of polymer matrices on the tensile and impact properties of long fiber-reinforced thermoplastic (LFT) composites, composites of long basalt fiber-reinforced thermoplastic were developed in this work. Two types of polyethylene, namely 8008 and 100S, and two types of polyethylene, namely C4220 and K8303, were chosen as the matrices. The fiber volume fractions were set as 2.8%, 5.9%, 8.1%, and 10.6%. The melt flow index (MFI), crystallinity, tensile properties, impact strength, and fracture morphology of the neat polymers and the corresponding composites were tested. The composites of 8008 showed the highest tensile strength since neat 8008 showed a much higher MFI value and crystallinity. The composites of 8008 and K8303 showed a much higher tensile modulus since the neat thermoplastic showed a higher tensile modulus than the other two composites. The polymer toughness was the factor that determined whether the polymer could be toughened by fibers. Moreover, the interfacial shear strength was calculated and compared with the matrix shear strength, based on which fracture modes of the LFT were predicted. Effective methods were proposed for further improvement of the mechanical properties. The results of this paper were essential for attaining the anticipated properties when designing LFT composites.

“…3 Fiber reinforced polymers (FRPs) are the most investigated and employed reinforced materials. 4 These materials will reach an estimated value of $114.7 billion by 2024 5 with carbon 6 or glass 7 fibers that are the main employed reinforcements. Specifically, 90% of fiber reinforced composites (FRCs) production is given by glass fiber (GF) reinforcement systems.…”

Polymers constitute the most employed reinforced matrices to achieve composite materials. Carbon and glass fibers are the reinforcements that are mainly utilized to improve specific properties for both thermoplastics and thermosets creating a new class of materials, which has been applied in several industrial fields. Various products made of fiber reinforced polymers are available on the market and at their own end-of-life, they must be reclaimed and remanufactured, properly, in an ideal recycling circular economy. The aim of this review is to point out the progress on fiber reclaiming from these materials, providing an overview on the most employed strategies and highlighting their main technological limits. Specifically, first, mechanical, thermal and chemical reclaiming processes have been contextualized introducing their peculiarities. Subsequently, the attention has been focalized on the new research trends proposed in the last years showing the direction, where the research is moving to. The processes have been also classified in terms of tensile strength of the reclaimed fibers and in terms of the energy required to be performed. Finally, design for reclaiming and remanufacturing treatments have been also considered pointing out the different approaches that can be pursued as valuable solutions to strengthen the recycling capabilities encouraging as much as possible the recovering of the polymeric matrix composites.
