Biopol Composites (TJBC) with nanoclay, and untreated jute fiber-reinforced biopol
composites (UTJBC) under mechanical analysis (DMA) and flexure tests. The results
have shown that, the 9% and 12% increase in the storage modulus and flexure
strength, respectively, when it is compared with the untreated jute fiber-reinforced
biopol composites (UTJBC). The respective values are 100% and 35% for 4%
nanoclay-infused TJBC, when it is compared with the UTJBC without nanoclay.
Lower moisture absorption and better mechanical properties are found in the
nanophased composites even after the completion of moisture conditioning. The flex-
ural results of untreated and treated jute-biopol composites are shown in Fig. 2.16A.
Surface-modified fibers resulted in flexural properties of these composites are also
determined after moisture absorption for 60 days (Fig. 2.16B).
