Abstract
The use of synthetic fibres resulted in environmental degradation and the growing interests towards the utilisation of readily available agricultural fibres as a potential replacement for synthetic fibres. This research aims to produce a ceiling board composite from piliostigma thonningii particulate using styrofoam adhesive binder. The board was produced from the readily available materials leading to the low cost of production. The composition has a formulation of fibre/binder mixing ratios (2:1, 1:1, 1:2 w:w), pressures of (100, 300, 500 kg/m 2 ) and temperatures of (30, 65, 100 °C) respectively. The process was successfully modelled and optimized using a Box–Behnken design method. The optimal conditions for the piliostigma thonningii board were found to be fibre/binder mixing ratio of 1:1 w:w, pressure of 500 kg/m 2 and temperature of 92 °C yielded response values of density (151.5 kg/m 3 ), water absorption (9.04 %), tensile strength (16.9 N/m 2 ), thermal conductivity (0.11 W/mK). Hence the board has greater insulating properties and good potential to be used as a ceiling board.
Highlights
Composite is a combination of two materials in which one of the material, called the reinforcing phase is embedded in the other material called the matrix phase [17].Ceiling board is composite products manufactured from particles of wood or other cellulosic fibre materials using adhesive as a binder.The important role of ceiling board: – creates a perfect ambience that can improve the acoustical system; – use as insulators and reduces heat transfer into the building; – adds value to the existing architecture of buildings; – use in holding up building materials.The rising concern towards the environmental issues on the one hand and the need for more versatile polymer-based materials, on the other hand, have led to increasing interest in polymers filled with natural lignocellulosic agro fibre
This paper aims at the production, optimisation and evaluation of the fundamental properties of ceiling board composite from piliostigma thonningii that can have a potential application of low thermal conductivity and help to preserve the environment by reducing the indiscriminate littering of Styrofoam
The boards have correspondingly lower densities compared to the standard boards

Ceiling board is composite products manufactured from particles of wood or other cellulosic fibre materials using adhesive as a binder. The important role of ceiling board: – creates a perfect ambience that can improve the acoustical system; – use as insulators and reduces heat transfer into the building; – adds value to the existing architecture of buildings; – use in holding up building materials. The rising concern towards the environmental issues on the one hand and the need for more versatile polymer-based materials, on the other hand, have led to increasing interest in polymers filled with natural lignocellulosic agro fibre. The Lignocellulosic fibres are low-cost raw material, abundant in nature and renewable. The less abrasive nature of the lignocellulosic fibres offered a friendlier processing environment and offered good thermal and insulating properties, recyclable and biodegradable especially when used as reinforcement in a biopolymer
