Man-made organic fibers (MMOFs) have been manufactured for over 50 years. Until recently, there have been few concerns raised regarding the safety of organic fiber dusts. This is due, in large part, to the perception that the dimensions of most, if not all, of these products were too large to be inhaled into the distal lungs of workers, i.e., were considered to be nonrespirable. A brief review ...

Reinforced polymer composites have played an ascendant role in a variety of applications for their high meticulous strength and modulus the fiber may be synthetic or natural used to serves as reinforcement in reinforced composites. Glass and other synthetic fiber reinforced composites consists high meticulous strength but their fields of applications are restrained because of their high cost of...

Resin transfer molding of an inorganic polymer binder was successfully demonstrated in the preparation of ceramic fiber reinforced engine exhaust valves. Unfortunately, in the preliminary processing trials, the resulting composite valves were too brittle for in-engine evaluation. To address this limited toughness, the effectiveness of a modified fiber-matrix interface is investigated through th...

in reinforced concrete design, there are situations where transfer of shear across a specific plane needs to be considered. examples of such situation include corbels, bearing shoes, ledger beam bearing, and a host of connection between precast concrete elements. in this study, the shear transfer behavior of reinforced concrete is investigated experimentally by conducting test on 6 precracked p...

Milling of fiber reinforced polymer composites is of great importance for integrated composites with other mating parts. Improper selection of cutting process parameters, excessive cutting forces and other machining conditions would result in rejection of components. Therefore, machining conditions are optimized to reduce the machining forces and damages. This work reports practical experiments...

C ommercially available fiberbased reinforcement for concrete is made of carbon, aramid, or glass filament fibers impregnated in a resin. Some aramid fiber reinforcement consists of aramid filaments without a resin matrix. For general applications, the most important feature of fiber-based reinforcement is its resistance to corrosion, which makes it ideal for reinforcing concrete exposed to hig...
