“…The genus Calotropis (Asclepiadaceae), which is native to the tropics and subtropics of Africa and Asia, has great potential for use as a fiber and medicinal plant 1 , 2 . Its long, fine seed hair (similar to that of cotton) is a high quality fiber, while the sap contains unique chemical compounds that have the diverse bioactive and pharmacological properties indicative of potential for new drug discovery 3 .…”

The genus Calotropis (Asclepiadaceae) is comprised of two species, C. gigantea and C. procera, which both show significant economic potential for use of their seed fibers in the textile industry, and of their bioactive compounds as new medicinal resources. The available wild-sourced germplasm contains limited genetic information that restricts further germplasm exploration for the purposes of domestication. We here developed twenty novel EST-SSR markers and applied them to assess genetic diversity, population structure and differentiation within Calotropis. The polymorphic information index of these markers ranged from 0.102 to 0.800; indicating that they are highly informative. Moderate genetic diversity was revealed in both species, with no difference between species in the amount of genetic diversity. Population structure analysis suggested five main genetic groups (K = 5) and relatively high genetic differentiation (FST = 0.528) between the two species. Mantel test analysis showed strong correlation between geographical and genetic distance in C. procera (r = 0.875, p = 0.020) while C. gigantea showed no such correlation (r = 0.390, p = 0.210). This study provides novel insights into the genetic diversity and population structure of Calotropis, which will promote further resource utilization and the development of genetic improvement strategies for Calotropis.

“…C. gigantea fibers from bark and seeds have been promoted as promising raw materials for fiber-reinforced composites [60 -63]. Polylactic acid (PLA) and polyester have been used as matrix polymers in combination with C. gigantea fibres as reinforcement material [64,65]. C. gigantea fibres exhibit a high degree of tubular hollowness (80-90%).…”

“…The authors reported that better results in tribological characteristics mainly wear behaviour by the addition of 3 wt % graphite as a filler which also acts as a solid lubricant and date palm fibre might improve mechanical properties of a composite material. Nasir and Ghazali 32 worked on biofibre and bioshell and Dilli Babu et al 33 have worked on Calotropis gigantea fruit fibre, Naresh kumar 34 have worked on Kevlar and natural fibres investigated fibre contribution on tribological properties of material; results reported that by addition of fibres to the parental matrix there should be decrement in specific wear rate and COF. In spite of presence of lubrication, material removal is somewhat difficult in biocomposite material compared to synthetic composite material.…”

In the past, asbestos and copper were preferred as friction materials because they have good ability to dissipate heat, but have proven to be harmful to environment. Recently, more researches are focused on non-asbestos friction composite materials due to its non-toxicity and biodegradability. Despite synthetic fibre composites having eco-friendly nature, because of its cost and pollution most of the researchers show interest on natural fibre composites. Hence, there is a need to explore the analysis on the tribologicaal behaviour of composite materials. The aim of this review is to provide overview of literature survey on the tribological characteristics such as friction, wear and lubrication of both particulate reinforced composites and fibre reinforced composites. In addition, operating and material parameters that influence tribological behaviour are also explored. Results reveal that operating parameters like normal load, sliding velocity, sliding distance, temperature and material parameters like particle size, volume fraction, fibre orientation, fibre length, surface treatment and aspect ratio have a significant effect on tribo characteristics.
