Structural reinforcement

The premise that discontinuous short fibers such as floating catalyst VGCF can provide structural reinforcements can be supported by theoretical models developed for the structural properties of paper Cox [36]. This work was recently extended by Baxter to include general fiber architecture [37]. This work predicts that modulus of a composite, E can be determined from the fiber and matrix moduli, Ef and E, respectively, and the fiber volume fraction, Vf, by a variation of the rule of mixtures,... 

Generally, adsorption, absorption, and biofilter units require more space than compact incinerators and condensers. If the plant room is restricted, a local roof-mounted system may be the best alternative. However, roof structural reinforcement may be required even for small and lightweight units. Consideration must be given to the effects of noise and vibration. Small adsorption systems, such as adsorption canisters, require an additional central regeneration unit on site, or they must be regenerated or disposed of off site. A central regeneration unit may require long runs of costly ductwork." ... 

The term may also be used with the meaning of structural reinforcement of rubber products, generally by combining the rubber with a textile material. 

In a limited sense, any material suitable for weaving or being made into a woven fabric. In the rubber industry the term is widened to include any material used for the structural reinforcing of a product and thus includes such materials as steel and glass not normally classed as textiles. See Cotton, Nylon, Rayon and Terylene. 

A particular constmction of filaments of rayon, nylon, Terylene, Kevlar or steel used as the structural reinforcement of pneumatic tyres. The cords were originally woven (cord fabric) but are now invariably used weftless. 

Cast nylon is used for prototypes and small production runs processed by casting, roto-moulding and reaction injection moulding (RIM), possibly with structural reinforcements (SRIM) such as glass mat or fabric. 

SRIM or SRRIM - structural (reinforced) reaction injection moulding - mats or fabrics are placed in the mould before injection of the resin, possibly reinforced with short glass fibres. 

A plastic waste processor (from Carderock Division) has been developed to compress the Navy s plastic wastes into discs, solving the environmental and space problems from 600 kg daily plastic waste (20 m ) per ship. Seaward International Inc and Carderock Division are developing a marine piling (The SeaPile) in structurally reinforced composite with a core made of these discs. 

Carbon fiber introduction into commercial markets happened in the mid-1960s and since then their application has increased substantially. Some of these applications include airplanes, spacecraft parts, compressed gas tanks, automotive parts, bridges, reinforced concrete, structural reinforcement, recreational sports equipment, and electrochemical systems [6,7]. 

Fuze, PD M572- It is an impact-type fuze similar to M557, except that is structurally reinforced by filling the ogive cavity with ca 2.5-oz of epoxy. The fuze is intended for use in 175-mm HE projectiles (Ref 52, p 5-47 no drawing)...

Structural reinforcement members should be installed on the vessel exterior wherever possible. However, if such members are installed internally, they shall be fabricated of simple shapes such as smooth round bars or pipe for ease of membrane lining application. 

SMMs are a class of magnetic molecules that exhibit borderhne behavior between classical and quantum physics and offer the possibihty of storing magnetic information at the molecular level. The incorporation of SMMs into new, multifunctional materials is thus expected to become a very fruitful research area in the near future. We have illustrated selected examples of Mni2-containing materials in which the SMM complex not only carries its unique magnetic properties, but also leads to structural reinforcement or enhanced electrical conductivity of a polymeric network. In fhis area, the importance of controlled structural alteration and molecular design cannot be overemphasized. 

However, if LCB is tied to structural reinforcement of the silica matrix, as proposed above, then for a constant degree of coalescence, low pore volume might be expected to raise LCB levels, because more points of contact between primary particles are generated, as illustrated in Scheme 21. Therefore, it was of interest to compare samples having the same degree of coalescence but differing widely in pore volume, to determine the independent effect of catalyst pore volume on LCB levels in the polymer. 

RubCon structures reinforced with steel-ribbed bars have a high bond stress due to adhesion and forces of mechanical bond. 

It has been known for some time that considerable improvement of the mechanical properties of alumina in terms of flexural strength, fracture toughness, yield strength and elastic modulus can be achieved by adding particles of stabilised zir-conia as a structural reinforcement (see Chapter 4.1.2). Such ceramics are known as ZTA (zirconia-toughened alumina), duplex ceramics or dispersion ceramics.

The mesoporous silicates MCM-41 and MCM-48 are members of the family M41S, which are of interest for adsorption and catalysis because their textural properties, i.e., pore size between 35 and 50 A and surface areas of about 1000 m /g [1-2]. These materials are being investigated as supports and catalysts for the processing of complex hydrocarbons, but they exhibit some drawbacks, such as a low hydrothermal stability and structural degradation in the presence of water. Thus, this work explores the structural reinforcement of the silicate walls of mesoporous MCM-41 materials by means of the coating with polymeric carbon, which can also modify their physicochemical properties...
