ILSS and impact strength are maximum for HSALMC.
Effect of filler content on tensile and flexural strength of HSALMC jute/polyester
composite is given in Table-4.

table 4.
S. No. Filler content, % Tensile strength, MPa Flexural strength, MPa

1. 0 47.2 65.6

2. 10 42.8 62.8

3. 20 37.6 59.5

4. 30 33.2 57.6

5. 40 28.3 54.2

It is observed from Table 4 that the effect of filler addition on tensile strength is far
more than that on flexural strength. At 40% filler content, tensile strength is reduced
by 40% while reduction in flexural strength is only 17.4%.
Moisture absorption by various jute/polyester composites is given table-5.

2. HSALMC 0.4

3. HSTHER 1.6

4. POLYESTER 0.2

Moisture absorption is the least for HSALMC.

In this chapter, the effect of fabric treatment and filler addition on mechanical perfor-
mance and moisture absorption of jute/polyester composites is investigated. Alkali
and thermal treatments were carried out on commercially available whole fabrics. Jute
fabric/polyester composites with calcium carbonate filler find many low cost applica-
tions.
