“…However, they are limited by linear elasticity and often exhibit brittle, sudden, and catastrophic failure, which occurs without warning. Thermoplastic composites reinforced with continuous fiber are receiving much attention and growing interest in the industry for lightweight applications owing to many attractive advantages in comparison to composites based on thermoset matrices; their advantages are mainly based on the inherent properties of thermoplastic polymers used, such as fracture toughness and damage tolerance (higher strain to failure), recyclability, clean processability (shaping prior to consolidation and the ability to be reshaped), faster manufacturing and long shelf life (Gonzalez-Chi et al, 2004;Hufenbach et al, 2011;Hassan et al, 2013;Fuller and Wisnom, 2015a;Shan-Shan et al, 2018). On the other hand, the joint between plies in thermoplastic laminates is formed by fusion, consequently there is no interphase, thus failure by delamination is not possible (common failure mechanism of thermoset laminates).…”

Thermoplastic multilayer composites with different fiber orientations were prepared with polypropylene and aramid fibers as reinforcing material. The prepregs were prepared in a continuous impregnation system using the dry powder method in a fluidized bed. The specimens were laminated by compression molding, tensile tested, and their fracture area was analyzed by microscopy. The mechanical performance of the laminates was influenced by the fiber orientation at the different layers. The fibers at 0 • conferred high stiffness to the composite, limiting the maximum deformation and promoting failure. The laminates with 0 • layers showed a fragile and sudden fracture oriented at 90 • to the aplied load, even with low fiber content. The plies oriented at ± 45 • balanced the stress and contributed to higher levels of deformation during the test due to fiber rotation toward the loading direction, also, no post-yield stiffening was found as in thermoset composites due to the ductile nature of the thermoplastic matrix; these layers limited the crack propagation in the transverse direction, canceling the in-plane shear stress. The fibers at 90 • acted as filler due to poor interface and did not contribute to the improvement of the composite mechanical performance. The evidence shows no delamination in the materials due to the tenacious nature of the thermoplastic matrix, neither saw-toothed or plateau region was found in the stress-strain curves in contrast to thermoset laminates.

“…A composite with 10% volume fraction of UD UHMWPE fibers and LDPE matrix was successfully fabricated, and the quality of the impregnation could be improved by reprocessing the composite. A higher volume fraction of 32% UD UHMWPE fibers in LDPE matrix was fabricated by Hinrichsen et al [ 207 ] whereas the production of self‐reinforced woven UHMWPE composites with 60% fiber volume fraction was reported by Mosleh et al [ 277 ] Dry powder impregnation method has also been applied to fabricate self‐reinforced PA composites as reported by Tohidi et al [ 35,51 ] and polyester‐fiber‐reinforced PP composites (Gonzalez‐Chi et al [ 22 ] ). But this method was rarely used to fabricate self‐reinforced PP and PET composites after a careful review study.…”

A review of the fabrication methods and mechanical behavior of continuous thermoplastic polymer fiber–thermoplastic polymer matrix composites

et al. 2022

View full text Add to dashboard Cite

Thermoplastic polymer fiber-thermoplastic polymer matrix composites (PPCs or PRFPs), often recognized as self-reinforced or single polymer composites, are potential candidates for future advanced polymer composites because of various advantages (e.g., recyclability, formability, low-cost, ultra-lightweight, environmental friendliness, etc.). The manufacturability and mechanical behavior of these composites compared to conventional carbon-/glass-/aramid-fiberreinforced polymers is of great interest to the composites community, but there are a limited number of studies in this area. To this end, this paper reviewed fabrication methods with different processing parameters and mechanical behavior of uni-/multi-directional thermoplastic PPCs featuring continuous thermoplastic Lisa D. Fring and Madhusudhan R. Pallak contributed equally to this study.

“…Usually, the chemical inertness of carbon fiber surface is not conducive to the adhesion of the resin and the formation of good fiber–resin interface 14,15 . Besides, thermoplastic resins usually have higher melt viscosity, which makes the preparation of thermoplastic prepregs more difficult than thermosetting prepregs 16–18 . The commonly preparation methods for thermoplastic prepregs include melt dipping, powder impregnation, and fiber hybrid 19 .…”

The synergistic steric hindrance effect in the preparation of polyether ether ketone composites by powder slurry method

et al. 2022

The preparation of continuous carbon fiber reinforced polyether ether ketone (PEEK) composites by the powder slurry method has many advantages, but the stability of PEEK suspension is required to be high. So far, there is a lack of in‐depth studies on the aqueous suspension of PEEK. In this study, two non‐ionic surfactants were selected for compounding. Then PEEK aqueous suspension and continuous carbon fiber reinforced PEEK composites were prepared. The stability mechanism of PEEK aqueous suspension with different surfactants was analyzed. Studies have shown that in the PEEK aqueous suspension, Triton X‐100 can help to infiltrate the PEEK powder. The steric hindrance of polyethylene glycol contributes to the stability of the suspension. The synergistic steric hindrance effect of the two surfactants can increase the stability time of PEEK suspension from 5 min to more than 50 min. The PEEK composites prepared by the powder slurry method has good quality stability, the fiber volume fraction is about 60%, the flexural strength of the composites can reach 1336 MPa, and the interlayer shear strength can reach 106 MPa. This study provides useful insights for the stability mechanism of PEEK aqueous suspension, and can guide the preparation process of thermoplastic composites by powder slurry method.
