Abstract Natural fibre-reinforced composites have attracted a great deal of attention by the automotive industry mainly due to their sustainable characteristics and low cost. The use is expected continuously increase in this area as cost weight vehicles could be partially reduced replacing glass fibre aluminium with natural composites. Adhesive bonding preferred joining method for increasingly ...

Antioxidant, anti-glycation and anti-inflammatory activities of fresh and conserved peach fruits (Prunus persica L. Batsch) were compared. Fresh peach pulps, peels, preserve peach pulps and the preserve syrup were prepared at equal concentrations. Rat liver, kidney and brain cortex tissue slices were pre-incubated with peach samples, subjected to oxidative stress with FeSO4 and hydrogen peroxid...

GLARE (glass-reinforced fibre–metal laminate ) is aluminum based material of fiber metal (henceforth FML) that often fabricated by expensive autoclave procedure. In this study, the process Injected Molding or (also known as VARTM was employed a cost-effective alternative to produce GLARE. Several surface preparation procedures are applied improve interlaminar shear strength. A T3 temper 2024 al...

The Bouligand structure is a typical helicoidal architecture found in various crustaceans which each layer rotates by small angle relative to the adjacent one. We present theoretical analysis relate rotation pitch mechanical performance (interlaminar shear property this case) of laminas mimicking architecture. For given laminate, there exists an optimal that yields lowest stress. Theoretical mo...

This paper focuses on a hydraulic radius separation approach used to calculate the boundary shear stress in terms of bed and wall shear stress proposed in a trapezoidal channel. The average bed and sidewall shear stress in smooth trapezoidal open channels are derived after using Guo & Julien (2005) early equations taking a part of an investigation to cover both rectangular and trapezoidal chann...

Increasing fuel prices and emission norms have favoured the automobile man- ufactures to use of lightweight materials. Land fill regulations imposed by many environmental governing agencies encourage products which will decompose easily or require lesser energy for recycling. In this scenario an attempt has been made in work develop natural fiber hybrid composites with synthetic fibers address ...

Layered composites subject to impacts can fail by delamination, i.e. by debonding between laminae, if the stress waves cause damaging phenomena to take place mainly within the resin-enriched interlaminar phases. To simulate delamination at the structural level, processes dissipating energy are lumped onto fictitious zero-thickness interlaminar surfaces, and softening interface constitutive laws...
