The effect of halloysite nanotube modification on wear behavior of carbon‐aramid fiber reinforced hybrid nanocomposites

Composite-aluminum hybrid adhesive joints represent an ideal solution for designing lightweight structures for the marine industry. However, seawater aging is a serious concern, limiting the safe service life of the joint. Notably, efforts to understand the impact of aging have largely focused on the shortterm periods without considering actual operating conditions. Here, we report the mechanical performance of hybrid joints subjected to the long-term stress aging. Besides, we modified the epoxy adhesive with halloysite nanotubes (HNTs) to limit the aging driven adhesive degradation and improve the adhesive's rigidity. We evaluated mechanical performances of hybrid joints by performing tensile, flexural, and drop-weight impact tests. While we increased the

“…For example, nanosilica, nanocarbon tubes, and various nanosized fillers or intensifiers are added to the materials to form composite materials. 36,37 The improvements caused by nanomaterials can be attributed to two aspects: (1) Nanosized particles of nanomaterials can cause changes in physical aspects, resulting in filling effects, and further improvement in mechanical properties [38][39][40] ; (2) Nanomaterials have higher surface energies, which strengthens the cementation between adjacent materials. [41][42][43][44] Among various nanomaterials, nano-SiO 2 (NS) is a useful nanomaterial, and it has low production costs and a good cementation effect.…”

A novel sand-fixing curing agent was developed and applied as a sustainable sand-fixing material. This research prepared a self-degradable, eco-friendly sand-fixing curing agent by using nanosilica and a polymer as the main raw materials (nanosilicon/polymer composite, NSPC), its mechanical properties and hydration mechanism were investigated. The results showed that adsorption of the NSPC on sand particles followed pseudo second-order kinetics, and the optimum mixing time of the NSPC and sand was 3 h. The compressive strength of the sample reached 6.07 MPa after 28 days with the optimal mass ratio of NSPC and sand. After 20 freezing-thawing cycles, the compressive strength was 3.25 MPa. The results indicated that the NSPC improved the sand's capacity for water retention. The chemical reaction between the NSPC and sand particles occurred at the microlevel and improved the sand strength by bonding the particles together. The NSPC curing agent satisfied the requirements of sand-fixing technology during 5 months of field tests. A mixture of the NSPC and sandy soil with a mass ratio of 1:3 is recommended for wind erosion control in the field. A field engineer in these situations may take advantage of the mixture to sprayed it onto the sandy surface.

“…[24] Introducing nanofillers into the matrix, according to earlier studies, can inhibit damage propagation through various nano-and micro-scale toughening mechanisms. [25][26][27][28][29] Graphene nanoplatelets (GNPs), carbon nanotubes (CNTs), nylon 6.6 nanofibers and nanosilicates are among the nanofillers being investigated to increase damage tolerance in FRP laminates after impact testing by triggering additional toughening mechanisms, including crack bridging and particle debonding. [30][31][32][33] Safamanesh et al found that incorporating the graphene oxide diminished the damaged area and improved damage tolerance, as well as the peak force and absorbed energy of the composite, were increased by 44% and 95%, respectively.…”

Although bolted composite joints are mainly designed to resist bearing loading, dynamic loading such as low‐velocity impact can also be a severe threat because of its potential to reduce joint reliability. Surprisingly, it is still unclear how bolted composite joints perform after the dynamic loading, and its effect on the damage tolerance is unknown likewise. This study aims to evaluate experimentally the bearing‐after‐impact (BAI) damage tolerance of bolted glass‐fiber (GF) reinforced epoxy composite joints. For this, the GF/epoxy composite laminates were assembled in single‐lap shear joints firstly, and the bolted composite joints were subjected to low‐velocity impact tests at various energy levels from 3 to 10 J. Following that, standardized bearing tests were carried out to determine the damage tolerance of the laminated composites following the impact. Nanoclay fillers were also added to the epoxy matrix to improve damage tolerance. After the low‐velocity impact loading, the bearing strength diminishes by almost 22% for the bolted composite joints, while the reduction in damage tolerance is effectively limited with the nanoclay addition. However, as the impact energy increases, the efficiency of the nanofiller declines. Increased impact energy results in changes in failure modes, and nanofillers improve damage tolerance with additional nano‐scale toughness‐increasing mechanisms.
