“…With the increase of environmental pollution and depletion of earth resources, environmental protection is becoming more and more important. [1][2][3] At present, numerous automobile parts need to use polymer-based composite materials. Nevertheless, when used as exterior parts, they often need to be sprayed.…”

In this work, jute fiber and aluminum (Al) powder were used synergistically to improve the mechanical properties and color of polypropylene (PP) composites, which can be used as spray-free materials. The effect of jute fiber and Al powder on the mechanical properties of PP composites was systematically investigated. The results show that jute fiber and Al powder can significantly improve the tensile strength and impact strength of PP. Compared with pure PP, the tensile strength, impact strength, and elastic modulus of jute/Al/PP composites were increased by 55.1%, 78.9%, and 263%, respectively. Compared with Al/PP spray-free materials, they were increased by 11.2%, 9.07%, and 103%, respectively. Statistical analysis by one-way analysis of variance confirmed that Al powder and jute fiber have significant improvement on the mechanical properties of PP composites.

“…During composite fabrication, hybrid yarn reduces the effective polymer flow distance and ultimately improves the thermoplastic polymer distribution in the composite structure . Many studies on NFCs made with hybrid yarn have been carried out but in most of the cases, natural fibers in the hybrid yarn structure are present in a twisted state, which is not desirable for strong NFC manufacturing . Zhang and Miao have designed and fabricated a composite using flax/polypropylene (PP) based comingled wrap spun yarn in which both the flax and PP fibers are in a twistfree state.…”

Influence of flax/polypropylene distribution in twistless thermally bonded rovings on their composite properties

Flax has a short fiber length that makes the control of fiber orientation in the composite structure very difficult, which leads to composites with inferior mechanical properties. In order to overcome this difficulty, thermally bonded roving (TBR) with a novel structure where the flax fibers are in a twistfree state and are highly oriented to the roving axis have been developed. In this study, the influence of flax/polypropylene (PP) based TBR structures on their unidirectional (UD) composite properties has been explored. In total, five sets of TBR samples with varying the flax contents (40, 50, and 60 wt% levels) and with varying degrees of flax and PP fiber mixing by changing the number of drawing passages (two times, four times, and six times) have been produced in a specially designed machine. The produced TBR samples are consolidated in a compression molding machine and the resultant unidirectional composites are tested for tensile, flexural, and impact properties. It has been observed that the tensile, flexural, and impact properties of the composite samples improve with increasing flax content and with increasing flax and PP fiber mixing in the roving structure. The present composite samples exhibit better mechanical properties compared to those reported for flax/PP composites in literature. It is mainly due to better fiber orientation and fiber-matrix distribution in the present composite samples.

“…2,3 Due to the advantages of the hybrid yarns production method, some researchers have recently used this method to develop a new generation of composites, such as bio-composites or eco-composites. 4–6 Several studies have been applying the hybrid yarns textile thermoplastic (HYTT) to produce lightweight and flexible composites. Moreover, some studies have presented the effect of variable parameters such as fiber content, chemical modification, and process conditions on the dynamic, mechanical, transport, microstructure, and fracture behavior properties of HYTT.…”

Nowadays, hybrid yarns, which consist of at least one-component thermoplastic fibers, are used in thermoplastic textile composites. The uniformity of the fibers in hybrid yarns is a key factor that directly influences the composite properties. Accordingly, one of the main aims of the present research was to optimize the air texturing parameters to achieve the uniform blending of Kevlar/polypropylene fibers. To evaluate the blending uniformity of yarns, the radial, lateral and angular distribution of fibers, based on the position of the pixels of the constituent fibers, was evaluated using the image processing data of yarn cross sections. According to this method, the production parameters, namely, blend ratio, delivery speed, feed rate and air pressure, were optimized simultaneously via the response surface method to obtain the blending uniformity of the fibers. The uniform blending distribution could be achieved by a higher blend ratio of Kevlar/PP (1:6), a lower production speed (300 m/min), a higher feed rate (500 m/min), and a higher air pressure (10 bar). Eventually, it was confirmed that there was a good correlation between the blending quality of the real samples and the predicted quality of the response surface method model.
