Mechanical Properties of Unidirectional Jute-Polyester Composite

Das S and Bhowmick M

Unidirectional compressed jute fibre sheets are prepared by using raw jute and jute sliver at 120ºC for 20 minute, at a pressure of 50 kg/cm2. Compressed raw jute fibre sheet produced from raw jute reed and jute sliver were used for preparation of the composites in unsaturated polyester resin matrix. Three different fibre content 25 (w/w)%, 35 (w/w)%, 44 (w/w)% composites were fabricated by using raw jute and jute sliver. Tensile, flexural, ILSS and SEM properties of composites made from raw jute and jute sliver were studied. The Tensile, flexural and ILSS properties of composites made from raw jute was found to be higher than composites made from jute sliver.

Comparison Mechanical Properties for Fabric (Woven and Knitted) Supported by Composite Material

Karnoub A, Makhlouf S, Kadi N and Azari Z

In many recent years the use of composite materials increases in many fields, for example agricultural uses, where these materials are characterized by good mechanical properties, tenacity and light weight. In this paper, we will shed light on the use of composite materials reinforced by knitted fabric compared with composite materials reinforced by woven fabric. Attachment materials was used in our research is resin, while supported cloth either woven or knitted were manufactured from amplified polypropylene filaments (BCF), and the testing are (tensile strength, resistance to bending, shear strength, resistance to penetration).

Comparing the results of composite material produced from knitted fabric shown better mechanical properties than woven fabric because of the knitted fabric distinct by the process of overlap between the stitches that gave better resistance.

Cutwork on Cotton Fabric

Himansu Shekhar Mohapatra, Neha Singh, Pooja Shukla and Sanat Kumar Pal

The tradition of cutwork appears to have emerged in 14th century Italy. Cutwork was very popular during the renaissance period. The term cutwork was how English writers described Italian drawn work. Cutwork embroidery was very highly by royalty and nobility. The patterns for cutwork embroidery differ from other embroidery patterns in that they have two outline lines, which are parallel to each other about 1/8th of an inch (1/3 cm) apart. It is some time called “embroidered lace” but it is not a true lace. This is similar to the appliqué work and differs from the other embroidery patterns. So in this paper, an attempt has been made to summarize the details of cutwork. Two different samples are made for the examples and details understanding of cutwork.
