Improving Impact Strength Recovery of Fractured and Healed Rice Husks Fibre R...IJERA Editor
Rice husks fibre reinforced polypropylene composite (rhfrpc) is a natural plant fibre reinforced polymer composite having advantages of high strength, light weight and affordability. They are commonly used for light load structural and non structural applications. They are mainly used as particle boards, for fencing post, roofing tiles, for interiors of car and aircrafts among other usages. This material once cracked by impact forces cannot be repaired using traditional repair methods for engineering materials such as metals or other composites that can be repaired by welding or by patch repair methods respectively, thus a method of repair of rice husks fibre reinforced polypropylene composites by refilling the damaged volume by injection of various healing agents has been investigated. The composite coupons were produced by injection moulding, cooled sufficiently and prepared for charpy impact tests. Test results for pristine coupons were a maximum of 48 J/mm2 . The destroyed coupons were then subjected to healing in a fabricated healing fixture. Healing agents such as epoxy resin, ethyl cyanoacrylate, and tannin gum have been investigated for their use as possible healing agents to fill the damaged volume and perform healing action at the fractured surfaces. The impact test results were recorded and compared with those of unhealed pristine coupons. The recovered strengths were a maximum of 60 J/mm2 translating into a 125% impact strength recovery, and this is good enough for the healed composites to be recommended for reuse in their second lives of their respective original functions.
La technologie numérique présente pas mal d'avantages. D'abord celui de pouvoir prendre un grand nombre de photos, qui peuvent être stockées sur une carte mémoire ou un ordinateur.
De ces avantages est néanmoins né un «problème».
Qui ne s’est jamais dit: «J’effacerai et je trierai mes photos plus tard ?».
Tout au long de notre article, nous vous présentons les applications incontournables pour organiser, modifier et sauvegarder vos clichés numériques, afin que vous puissiez dorénavant protéger au maximum de vos photos.
Il existe de nombreux sites proposant le stockage de photos en ligne. Toutefois, ceux proposant un service gratuit et performant ne sont pas légion !
Interney blogs como micromídia digital: Elementos para o estudo do encadeamen...Alex Primo
Este trabalho visa ampliar o debate sobre os níveis midiáticos, propostos por Thornton (1996), através da proposta da sub-categoria micromídia digital. A partir disso, o conceito de contrato social de Charaudeau é operacionalizado na análise do portal Interney Blogs. Finalmente, o conceito de encadeamento midiático é discutido.
