Some mechanical properties of untreated jute fabric-reinforced polyester composites

Abstract: This research work is concerned with the evaluation of the mechanical properties—modulus, Poisson's ratio and strength—of woven jute fabric-reinforced composites. The specimens are prepared using hand lay-up techniques as per the ASTM standard. This is the first report by any single group of researchers in which tensile strength, compressive strength, flexural strength, impact strength, inplane shear strength, interlaminar shear strength and hardness are given. This work being an experimental study on untreated (`as received' jute fabric) woven jute fabric-reinforced polyester composites, demonstrates the potential of this renewable source of natural fibre for use in a number of consumable goods.

Seismic Shear Strength of Reinforced Concrete Columns

Abstract: Aspects relating to the shear strength of circular and rectangular columns under seismic loading are presented An examination of existing design equations reveals wide differences in predicted responses Particular emphasis is placed on models capable of representing the interaction between flexural ductility and shear strength A simple method is proposed whereby the strength enhancement provided by axial compression is separated from the concrete component of shear strength and considered to result from arch action The strength of the concrete component is reduced as flexural displacement ductility increases Prediction of shear strength from the proposed and alternative methods are compared with results from a wide range of tests of columns failing in shear The proposed method is shown to provide significantly improved correlation with experimental results Conservative modifications are made to enable the method to be used for design

Cobalt-based bulk glassy alloy with ultrahigh strength and soft magnetic properties

Abstract: Bulk metallic glasses—formed by supercooling the liquid state of certain metallic alloys—have potentially superior mechanical properties to crystalline materials. Here, we report a Co43Fe20Ta5.5B31.5 glassy alloy exhibiting ultrahigh fracture strength of 5,185 MPa, high Young's modulus of 268 GPa, high specific strength of 6.0 × 105 Nm kg−1 and high specific Young's modulus of 31 × 106 Nm kg−1. The strength, specific strength and specific Young's modulus are higher than previous values reported for any bulk crystalline or glassy alloys1,2,3. Excellent formability is manifested by large tensile elongation of 1,400% and large reduction ratio in thickness above 90% in the supercooled liquid region. The ultrahigh-strength alloy also exhibited soft magnetic properties with extremely high permeability of 550,000. This alloy is promising as a new ultrahigh-strength material with good deformability and soft magnetic properties.
