امروزه کامپوزیت های لایه ای فلزی- الیافی fml به دلیل دارا بودن خواص مکانیکی خوب و وزن کم بسیار مورد توجه طراحان، به ویژه صنایع هوافضا قرار گرفته است. کامپوزیت های fml خواص بهتری نسبت به هر دو آلیاژ آلومینیوم و مواد کامپوزیتی از خود نشان می دهد. در این پژوهش، خواص خمشی این کامپوزیت ها مورد بررسی عددی- تجربی قرار گرفته است. از آنجایی که این چندلایه ها دارای قابلیت فرم دهی محدود می باشند و فایبرها...

The effect of Kevlar fibre surface modification and hybridization on metal laminates (FMLs) was investigated in this paper. Fibre are interlaced layers thin metals fibre-reinforced plastics that constitute a hybrid composite material. flexural strength composites from the three-point bending test at various ratios sequence FML composites. Glass fibre, aluminum were taken for laminating reinforc...

BACKGROUND Allergan's Natrelle round silicone-filled breast implants were approved by the U.S. Food and Drug Administration in 2006 based on interim results from the Core Study; final 10-year study results are now available. METHODS Seven hundred fifteen subjects were implanted with smooth and Biocell textured Natrelle round silicone implants and attended clinic visits at 0 to 4 weeks, 6 mont...

Steroid responsiveness to dexamethasone was determined in a large family with an established dominant form of chronic simple glaucoma. The high and intermediate steroid responders were then tested with fluorometholone--a steroid which is claimed to have a reduced risk of increasing intraocular pressure. It was found that fluorometholone had a much less pronounced ocular hypertensive effect than...

N-Formylmethionylleucylphenylalanine (fMLP) induces chemotaxis in leukocytes, the response being mediated by peptide binding to a receptor on the plasma membrane. In tumor cells, this peptide has been reported to induce cellular swelling and chemotaxis in vitro and to enhance the localization of circulating tumor cells in vivo. In the Boyden chamber, we evaluated the migratory responses of Walk...

This paper aims to experimentally and numerically probe fatigue behaviours lifetimes of novel GLARE (glass laminate aluminium reinforced epoxy) laminates under random loading spectrum. A mixed algorithm based on damage concepts three-phase materials was proposed for modelling progressive mechanisms life fibre metal (FML) To validate the algorithm, tests were conducted 2/1 3/2 subjected spectrum...
