Water vapor diffusion through glass fiber reinforced polymer nanocomposites
Fiber reinforced plastics (FRPs) are used to make aircraft structures, highway bridges, automobile components, storage tanks, boat hulls, truck beds, and so on. When these FRPs are exposed to the atmosphere, environmental humidity can weaken the structural integrity and cause fiber delamination. …

Flexural behavior of a glass fiber reinforced wood fiber composite
… static and dynamic flexural properties of a wood fiber matrix internally reinforced with continuous glass fibers were investigated. When modelled as a sandwich composite, the static flexural modulus of elasticity (MOE) of glass fiber reinforced hardboard could be successfully predicted from the …

Development and evaluation of glass fiber-reinforced composite/wood railroad crossties
Railroad crossties are strengthened by wrapping glass fiber reinforced composites (GFRC). In addition, durability of crossties has been found to have enhanced by reinforcing them with GFRC wraps. In order to reduce the cost, GFRC wraps are not used to wrap the entire length of a crosstie, but only …

Modeling of Microstructures and Stiffness of Injection Molded Long Glass Fiber Reinforced Thermoplastics
… of the use of injection molded discontinuous fiber-reinforced thermoplastics. During the intensive injection molding process, severe fiber breakage arises in the plasticating stage leading to a broad fiber length distribution. Fiber orientation distribution (FOD) is another highly anisotropic …

Bending behavior of concrete T-beams reinforced with glass fiber-reinforced polymer (GFRP) bars
Concrete slabs are integrally cast with girders or stringers (stiffening system) resulting in floor slabs, bridge decks, footers, retaining structures and others. A portion of slab between a stiffening system acts as flange and bends in unison with the stiffening system, i.e., classic T-beam …

The Effect of Root Canal Cleansing on the Retention of Glass Fiber-reinforced Posts
<p>Esthetic glass fiber-reinforced posts are being used more often. The most commonly reported complication associated with these posts is debonding. Dentine conditioning with solutions such as EDTA or MTAD results in removal of smear layer and might improve the retention of posts to root canal …
