Luffa Fiber
Its density is between 082 and 092 g cm -3 Dairo et al. All results obviously showed that damping characteristics of Luffa cylindrica composite is higher than glass fiber composite materials.
The scientific name of the species is Luffa aegyptiaca.
Luffa fiber. Effects of volume fraction on the Tensile Compressive Flexural Impact strength were studied. The luffa fiber has a high content of cellulose 60 hemicellulose 15 lignin 10 and other components Mazali and Alves 2005. 2018 and cotton 151 g cm -3 Abbott et al.
Luffa is a plant from the cucumber family grown for its multipurpose fruit Figure 1 in many tropical coun-tries. Luffa fiber is treated using benzoyl chloride and NaOH. As a dynamic test vibration tests were fulfilled using hummer.
Scrubbing removes dead skin cells and dirt from the surface of the skin and pores. As a dynamic test vibration tests were fulfilled using hummer. Luffa cylindrica fiber and glass fiber were used as reinforcements and epoxy resin was used as a matrix to make up the composite specimens.
Exfoliation is known for stimulating skin health and loofah Luffa is one of the most popular tools for exfoliation. Luffa cylindrica the sponge gourd Egyptian cucumber or Vietnamese luffa is an annual species of vine cultivated for its fruit native to South and Southeast Asia. The luffa fibers were collected from the local farmers at Kuching Malaysia although it can be found all everywhere in Malaysia as it is a local common vegetable.
Moreover the surface of the fiber possesses abundant hydrophilic hydroxyl groups so researchers are devoted to prepare luffa cylindrica-based materials by introducing effective functional groups on the surface of fibers which is conducive. It is found in tropical and subtropical countries of Asia India China Pakistan and Indonesia Africa and South America. Luffa cylindrica fiber and glass fiber were used as reinforcements and epoxy resin was used as a matrix to make up the composite specimens.
Tensile and flexural tests are conducted on composites to investigate the effect of chemical treatment. Luffa- cylindrica locally called as sponge-gourd is one such natural resource whose potential as fiber reinforcement in polymer composite has not been explored till date for tribological applications. Although luffa natural fiber composites have revealed promising properties the addition of these natural fibers increases water absorption.
Luffa cylindrica consists of cellulose 60 hemicellulose 20 and lignin 10. The Luffa genus encom-passes seven 7 species among which Luffa aegyptiacaand Luffa acutangu laare primarily grown for its fibre production. Luffa fiber is not a single filament like glass fiber but rather a bundle of cellulose fibrils making a fibrous vascular system in a hierarchical structure.
It has a density of 092 gcm 3. 2007 which is lower than other studied biomass including sisal 126 g cm -3 Dun et al. Luffa fiber and Ground nut reinforced epoxy resin matrix composites have been developed by hand lay-up technique with luffa fiber treated conditions and Ground nut with different volume fraction of fibers as in 11 ratio 10 20 30 40 and 50.
Friction from scrubbing also expands capillaries in the skin to stimulate blood flow. It is an annual climbing or trailing herbaceous species that can be 15 m long. 2019 hemp 148 g cm -3 Battegazzore et al.
All results obviously showed that damping characteristics of Luffa cylindrica composite is higher than glass fiber composite materials. It consists of cellulose 63 hemicellulose 209 lignin 117 and ash 04. It has a ligneous netting system in which the fibrous cords are disposed in.
Luffa-cylindrica locally called as sponge-gourd is one such natural resource whose potential as fiber reinforcement in polymer composite has not been explored till date for tribological applications. Luffa cylindrica is a natural fiber with high mechanical strength and excellent stability.
