| Description |
Additives provide substantial improvement in the properties of composites. Although biobased composites are preferred over synthetic polymer and metal-based composites, they do not have
the requisite properties to meet specifc needs. Hence,
organic, inorganic and metallic additives are included
to improve the properties of bio-based composites.
Coal is a readily available resource with high thermal insulation, fame resistance and other properties.
This work demonstrates the addition of 20–30% natural sub-bituminous coal as fller for coir-reinforced polypropylene (PP) composites and exhibits an
increased tensile strength by 66% and fexural
strength by 55% compared to the composites without
any fller. Such composites are intended for insulation
applications and as a replacement for gypsum-based
false ceiling tiles. Various ratios of coal samples
were included in the composites and their efect on
mechanical, acoustic, thermal insulation, fame and
water resistance have been determined. A substantial
improvement in both fexural and tensile properties
has been observed due to the addition of coal. However, a marginal improvement has been observed in
both thermal conductivity (0.65 W/mK) and fame
resistance values due to the presence of coal. Adding
coal increases the intensity of noise absorption, particularly at a higher frequency, whereas water sorption
of the composites tends to decrease with an increase
in the coal content. The addition of coal improves
and adds unique properties to composites, allowing
coir–coal–PP composites to outperform commercially
available gypsum-based insulation panels.
