An investigation into sound transmission loss by polypropylene needle-punched nonwovens

Abstract

In this work, the effects of variables such as initial carded web mass, needle penetration depth, punch density, and the frequency of incident sound wave on transmission of sound through polypropylene needle-punched nonwovens were investigated. Fibrous carded webs using commercially [...]

Investigations on surface quality characteristics with multi-response parametric optimization and correlations

Abstract

This paper presents the parametric optimization on surface quality characteristics (Ra, Rz and Rt) in hard turning of EN31 steel using multilayer coated carbide insert (TiN/TiCN/Al2O3) and also finds correlations. The experiments have been conducted based on Taguchi’s L9 orthogonal [...]

A hybrid multi-output approach to optimisation of PVC pipe quality characteristics

Abstract

A hybrid multi-output approach which combined the Taguchi method and fuzzy logic was used in this research in order to optimise the mechanical and physical properties of PVC pipes. Eight techological parameters which mostly define the extrusion process were taken into consideration [...]

Statistical Analysis of Sulfate Attack Resistance of Reactive Powder Concrete

Abstract

This paper is the study of sulfate attack resistance of reactive powder concrete (RPC). RPC that is also known as ultra-high performance concrete is a special type of concrete material obtained when fine powders like silica fume (SF) are added into the concrete mortar along with very [...]
