“…Figure f shows the density variation of Ni–Fe–P-coated BFs with different deposition amounts; the result reveals that the weight of 56.25% Ni–Fe–P-coated BFs is 2.6 times that of raw BFs. The excellent electrical, thermal, and magnetic properties of coated BFs also predict their application prospects in multifunctional polymer composites, which will be further discussed in our future work. − …”

As environmental stress is caused by using fossilbased plastics, bamboo fibers (BFs), as one of the important natural materials, have received more and more attention. However, their poor thermal stability and lack of functionality largely limit their wider application. In this work, the electroless plating method was used to improve the thermal stability of the BFs and impart this function. It was found that the amount of metal deposition was the main factor affecting the thermal stability of BFs. A critical value existed, above which the surface of BFs could be completely covered by a plating layer, resulting in much enhanced thermal stability. The initial degradation temperature of BFs could be improved by 31 °C, as detected by TG. XRD and TG-FTIR spectroscopy were used to further understand the observed increase in thermal stability induced by electroless plating. It is suggested that the coating layer could block the invasion of external O 2 , thus delaying the degradation time and the pyrolysis rate. It is also very interesting to find that hygroscopicity and electrical and magnetic properties could be simultaneously improved. Our work provides a new method for the modification of BFs, which is important for the application of BFs.

“…In terms of pultrusion, initial trials showed that bi-component fibres can readily be processed in setups designed for commingled-fibre pultrusion. In a test case of pultrusion of ∅5 mm thermoplastic rods, bi-component fibres showed a significant effect of lowering the void content [134]. This demonstrates that there is a clear potential for bi-component fibres to become a material concept for high-speed pultrusion of low void content profiles.…”

“…The effects of variation in the roving/yarn can to some extend be compensated for with smaller strand diameters. Another route is multiple die applications [141] or bi-component fibres [134], but with larger nozzle diameters and high reinforcement content, intra-and inter-strand porosities together with insufficient drapeability at corners can arise.…”

The thermoplastic composites which in the automated tape placement (ATP) process are directly consolidated and formed in situ. The interlaminar bonding quality of the product is susceptible to the ATP process. Glass fiber‐reinforced bio‐based polyamides PA5X (GF/PA5X) tapes are used to prepare samples. The effect of process parameters on the interlaminar bonding quality is explored by peel test based on the principle of the response surface. A quadratic response surface model of hot gas temperature, placement speed, and roller force on the peel strength is established, and experiments are conducted to verify the accuracy of the model. The effect of process parameters and their coupling effect on the peel strength is obtained. The interlaminar bonding quality of the samples manufactured by ATP and compression molding are comparatively analyzed through peel and short beam shear tests. The results show that the best combination of process parameters obtained is: the hot gas temperature of 619°C, placement speed of 0.540 m/min, roller force of 684 N, and predicted peel strength of 9.89 N/10 mm. The peel and short beam shear strength of the samples manufactured by ATP is 9.96 N/10 mm and 34.2 MPa, reaching 66.0% and 60.0% of the samples manufactured by compression molding respectively.Highlights GF/PA5X thermoplastic composite tapes are used to prepare ATP samples. The effect of process parameters on the interlaminar bonding quality is explored. The micromorphology of the ATP samples is characterized. The ATP and compression molding samples are comparatively analyzed.
