BisGMA/jute fibre/fly ash hybrid composites
Abstract
Purpose
This paper aims to prepare BisGMA (bisphenol-A glycidyldimethacrylate)/jute fibre/fly ash hybrid composites with improved mechanical and corrosive properties.
Design/methodology/approach
BisGMA prepolymer was first synthesised using diglycidyl ether of bisphenol-A and methacrylic acid. Then 2-hydroxy ethylacrylate-treated jute fibre and sodium hydroxide-treated fly ash were incorporated in the fabrication of composites using dicumyl peroxide, cobalt naphthenate and N,N-dimethyl aniline as catalyst, accelerator and promoter, respectively. The composition of BisGMA, jute fibre and fly ash was kept constant, whereas treated and untreated jute fibre and fly ash were used alternatively.
Findings
Treatment of both jute and fly ash leads to improved mechanical properties of composites. However, treated fabric plays a dominant role compared to treated fly ash as filler. Among all the composites, the one having both treated jute fibre and treated fly ash is the most suitable composite for structural applications.
Research limitations/implications
The present investigation has come up with a hybrid composite that can be used for a wide range of applications like low-cost housing and structural projects, structural laminates, etc., as it is both corrosion- and moisture-resistant. It is also the most durable from the mechanical point of view. There is also a scope of using other fillers instead of fly ash to study the changes brought about in the mechanical properties.
Originality/value
The above composites have never been fabricated before.
