摘要：The natural fibres are gaining interest among the researchers because of its various
properties. The natural fibres can be reinforced effectively in various polymers by
different methods. The Natural Fibre Composites (NFCs) have wide range of applications
and by using these plastic usages can be minimised. The ability to absorb or to reject heat
is an important criterion in electrical and thermal industries. Only a few studies have been
done on the powdered form of sisal. In this study an attempt is made to find out the heat
absorption/rejection capacities of powder and short fibre sisal composites for different
weight fractions through Differential Calorimetric Analysis (DSC) and the corresponding
mechanical strengths were studied. To improve the strength of the composites, fibres were
treated in Na-OH solution. The reinforced plastics showed better heat absorption and
rejection than the pure polymer but less mechanical strength. The powdered form of
composite showed better properties than 20 mm fibred composites. The composite with a
10 mm length and 10 percent fibre loading showed best heat absorption/rejection
capacities. The treated fibre composites showed improved strength than the untreated
fibre. The same composite showed best mechanical properties also. The DSC analysis of
the treated fibre showed lesser heat capacities.
