“…Untreated SP fiber with 1% BFA and CFA showed higher surface roughness when compared to treated SP fibers. Alkali treatment provides wet resistant and rough fiber which improves the compatibility between fiber/matrix and decreases the surface roughness in the natural hybrid composites [29]. Similarly untreated SP fiber with 3% BGFA showed higher surface roughness than treated fibers.…”

“…The higher filler addition at 4% BFA reduces the MRR due to agglomeration effect, which damages the matrix properties. Agglomeration reduced the load carrying and stress transfer capacity, which ultimately reduces the machining nature of the epoxy based composites [29]. Hybrid fiber composites with out filler showed brittle failure at higher WP and it also severely damage the fiber/matrix bonding [27].…”

“…The filler substitution produces a protective layer from the high kinetic energy abrasive particles hitting the work piece. This reduces flush off the fiber composite materials thus improving the machining nature of the composites [29].…”

“…Sodium hydroxide treatment at 4% enhanced the machining property of coconut shealth natural composites. It improved the compatibility between filler and polyester matrix [29]. Apart from that, natural fillers such as calotropis gigantean stem powder, azadirachta indica seed powder, spent camellia sinensis powder along with graphene powder was used for enhancing the properties of natural fiber composites [30][31][32].…”

This research was based on influence of various fly ash filler content in the machining properties of Pineapple (P)/Sisal (S) hybrid fiber reinforcement composites. Fly ash from bio waste materials of Bagasse (BGFA), Banana (BFA) and Coir (CFA) were used. High hardness nature of 3% BFA (22.73 HV) and 3% CFA (23.85 HV) reduces Material Removal Rate (MRR) and increases its surface roughness nature of the composites. Maximum MRR of 376.38 mm 3 min −1 was observed in 3% BGFA combinations with 250 MPa Water jet Pressure (WP), 1mm Standoff Distance (SOD) and 20 mm min −1 Traverse Speed (TS) as machining parameters. MRR of 353.64 and 352.76 mm 3 min −1 was found out with 1% CFA and 1% BFA combinations. Lower surface roughness of 6.39 μm, 6.71 μm and 6.75 μm was found in 3% BGFA, 1% CFA and 1% BFA based composites. Filler surface created a tight bonding with the matrix, which reduces the erosion of fiber particles at higher WP. Untreated fibers showed lesser machining properties due to low fiber/matrix bonding. SEM results showed reducing of cracks and matrix breakages by the substitution of filler powders.

“…Besides, the existence of γ-GPS silane can obviously improves stability of the hydrolysate, but excessive content of absolute ethanol may inhibit the hydrolysis of γ-GPS silane, leading to the less formation of Si-OH groups in the hydrolysate, and this will be detrimental for the adhesion to organic epoxy coating [8]. 1.2-bis(trimethoxysilyl)ethane (BTSE) belongs to hydrophobic silane, and it is insoluble in water, and needs to be hydrolyzed in the presence of a large amount of absolute ethanol [9]. Studies show that the hydrolysis rate of BTSE silane is very slow in pure absolute ethanol solvent [10].…”

In this investigation, the mixed γ-GPS/BTSE silane solution for preparing well adhered composite γ-GPS/BTSE silane film on Q235 carbon steel surface has been successfully optimized by orthogonal test, and the curing process parameters of temperature and time have also been optimized. The results indicate that the optimized hydrolysis parameters for mixed silanes agent solution are as follows:silanes 6 vol.%, pH 4.0 and hydrolysis time 72 h. In addition, the optimized curing condition for composite γ-GPS/BTSE silane film is 120°C and 30 min. After immersion in the optimized mixed γ-GPS/BTSE silanes agent solution and curing under the optimized condition, the prepared composite γ-GPS/BTSE silane film on Q235 steel surface can have an adhesion strength of 24.52 MPa to underlying steel substrate.
