“…The TPU‐1CNTs have an improvement in tensile properties equivalent to TPU‐6CB (5.404 MPa). Compared to TPU‐6CB, the tensile property of TPU‐3CNTs was increased by 40.17% . The Young's modulus increased with the increase of CNTs content in the TPU, and the change in elongation at break showed the same tendency as the Young's modulus.…”

“…A sand‐blasting instrument (BH‐1350, Shenzhen Datong Co., Ltd) was used to study the erosion performance for the sample (20 mm × 4 mm × 0.4 mm) which was tightly attached to a stainless steel plate. In order to describe solid particle erosion performance better, erosion rate (ER) was defined from the weight loss of the sample due to the weight of the erodent as the following formula:

ER = \frac{W_{m}}{W_{p}}

where W m is the weight loss of CNTs/TPU film and W p is the weight of the impact particles (testing time × feed rate), and the weight of CNTs/TPU film was recorded by precision balance.…”

“…Since the pioneering work done by Reynolds in 1873, the categories and mechanisms of solid particle erosion have been continuously studied. For example, Hutchings and Bitter defined the solid particle erosion as material damages caused by the repeated impact of small particles against material surface .…”

“…In this work, CNTs/TPU mixture was added into the poor solvent methanol of TPU and CNTs/TPU nanocomposites precipitated together, keeping the good dispersion of CNTs in the TPU matrix. The effects of carbon black (CB) on the TPU erosion performance was previously studied . However, compared with CB, CNTs have a larger specific surface area and can be combined with polymer matrix more effectively.…”

A co‐coagulation method combined with hot pressing technique is successfully applied to fabricate thermoplastic polyurethane (TPU) nanocomposites with different contents of carbon nanotubes (CNTs). Obviously, the mechanical and thermal properties of the nanocomposites are improved with increasing the CNT content. In addition, the existence of hydrogen bonding between CNTs and polymer matrix is demonstrated. Furthermore, the influences of impact parameters on solid particle erosion behavior are investigated systematically. The surface roughness and line roughness are also investigated to illustrate the mechanism of solid particle erosion. As elastic nanocomposites, the maximum and minimum erosion rate (ER) occur at 30° and 90°. The ER is relatively small when the impact velocity is at 10 m s−1, then is increased rapidly between 20 and 30 m s−1. As the size of impact particles increases to 300 µm, a rapid increase of ER occurs between 10 and 20 m s−1. All these results indicate CNTs improve the erosion resistance of TPU matrix.

Silver nanoparticles/polymer composite (Ag‐NPs/PC) may eventually be biodegradable, sustainable, or burned without production of lethal by‐products and can be utilized as packaging and biomedical device applications. Nanoparticles engaged in pine gum (resin and rosin) are preserved for months without any significant effect on particle size and distribution. This paper focuses on the pine gum/epoxy composites with and without silver nanoparticles fabricated by a hand lay‐up technique. Silver nanoparticles are fixed at 0.37% and pine gum varies from 2 to 24% by weight to acquire the best mechanical and wear properties. The result indicates that Ag‐NPs with pine gum (23.7 wt% resin &13.3 wt% rosin) has the best tensile and impact strength reaching a gain of 51.34% and 53.68% simultaneously. Hardness is noted most extreme 17.92% at Ag‐NPs sample (7.4 wt% resin and 3.7 wt% rosin) and wear resist behavior is best noted with neat pine gum/epoxy composite. The antibacterial assay of the Ag‐NPs is done against Escherichia coli and noted that the zone of inhibition is found to be 1.6 cm as compared to inhibition of 0.4 cm for pine gum reaching an advance of 75%. The various arrangements are enhanced and sited on the basis of TOPSIS technique.

This research introduces novel flexible spherical carbon nanoparticle‐based polyurethane conductive ink, which is employed to 3D print strain sensors by a lab‐developed Direct Ink Writing system. Rheological tests are performed, and sensors are pasted on Glass‐Fiber‐Reinforced Plastic specimens to study strain gauge behaviors under quasi‐static loading. The gauge factor in tensile loading is found to be layer width dependent as decreasing the strain gauge’s layer width increases the sensitivity of the strain sensor. A maximum gauge factor of 34 is achieved using a layer width of 0.2mm, 17 times greater than commercially available metal foil strain gauges. The four‐point bend tests are performed under tension/compression to assess the sensor’s strain‐sensing and damage‐monitoring ability. Fractographic analysis is coupled with strain monitoring using the developed sensor, which confirms that the failure progresses from intralaminar failure modes such as ply splitting in tension. At the same time, delamination leads to kink band formation under compression and the eventual failure of load‐bearing fibers. The developed sensor exhibits repeatable performance with low hysteresis and integrated non‐linearity errors for up to 1000 cycles. The developed sensors could be effectively employed for online in‐situ structural health monitoring of structures in different applications under static and dynamic loading.This article is protected by copyright.
