Eco-Friendly Multipurpose Lubricating Greases from Vegetable Residual Oils

Lubricants, 2015
Environmentally friendly multipurpose grease formulation has been synthesized by using Jatropha vegetable residual oil with lithium soap and multifunctional additive. The thus obtained formulation was evaluated for its tribological performance on a four-

Structural characterization and optimum machining parameters of jute/carbon fibre hybrid reinforced epoxy composite laminates

Polymer International, EarlyView.
Hybrid jute/carbon epoxy laminates have better mechanical performance and less drilling damage by the use of optimized stacking sequence and machining parameters. Abstract Three composite laminate systems were produced using the standard hand lay‐up method: jute‐fibre‐reinforced polymer (JFRP), carbon‐fibre‐reinforced polymer (CFRP) and a hybrid of the

Influence of Viscous Dissipation on Wear Behavior and Hardness Evolution of Tool Steels in Glass‐Fiber‐Reinforced Polymer Processing

steel research international, EarlyView.
Tool steels tested under injection molding conditions with glass‐fiber‐reinforced polymers, revealing how viscous dissipation drives hardness loss, even in PM grades. A sharp rise in wear with increasing injection volume rate and thermomechanical load uncovers striking material differences.

Tailoring Laser Powder Bed Fusion and Post‐Processing Parameters for JIS SKD61 Tool Steels: Surface Roughness, Microstructure, and Mechanical Properties

steel research international, EarlyView.
Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61
