Glass fiber reinforcement plastics

Some design factors, however, work against composites. For example, glass fiber-reinforced plastics generally have lower modulus (stiffness) than metals. Thickness and shape adjustments are requited where stiffness is a critical design requirement. With appropriate reinforcement, any modulus, even greater than that of metals, can be achieved. However, it may become expensive and uneconomical to do so. [Pg.97]

In the gas cleaning sections of spent acid or metaUurgical sulfuric acid plants, the weak acid scmbbing circuit is typicaUy handled by plastic or glass fiber reinforced plastic (ERP) pipe. The contaminants in weak acid usuaUy vary too greatly to aUow use of an economical aUoy. [Pg.188]

The economically most attractive glass fiber-reinforced plastics for high technical use are, next to RTM and winding technology, etc., semi-products made of SMC and BMC systems. [Pg.802]

As is known of glass fiber-reinforced plastics, the mechanical and physical properties of composites, next to the fiber properties, and the quality of the fiber matrix interface, as well as the textile form of the reinforcement primarily depend on the volume content of fibers in the composite.

About 8,000 metric tons of peroxides were consumed in 1972. This consumption was strongly stimulated by the rapid growth in reinforced plastics (Ref 23). The largest volume product is benzoyl peroxide which is used in polystyrene and polyester markets for such items as toys, automobiles, furniture, marine, transportation and mil requirements. Also, methyl ethyl ketone peroxide is used in large volumes to cure (as a catalyst) styrene-unsatur-ated polyester adhesive resins used in mil ammo adhesive applications, as well as in glass fiber reinforced plastic products such as boats, shower stalls, tub components, automobile bodies, sports equipment, etc. The monoperesters are growing slowly because of some substitution of the peroxydicarbonates and azo compds (Refs 8,9 23)...

The Chemical Propulsion Division of Hercules was formed in 1958, and began construction of a major facility for design development and manufacture of large rockets and propellants at the Bacchus, Utah plant. In 1958 Hercules acquired the design, development, and production facilities of Young Development Laboratories of Rocky Hill, N J. The filament-wound, glass fiber-reinforced plastic Spiralloy structures... [Pg.66]

Time-temperature superposition works for homopolymers and miscible blends but not for immiscible blends, filled systems (e. g., glass fiber reinforced plastics) or reactive or unstable polymers. [Pg.45]

A thermohardening composition for glass fiber reinforced plastics consists of PPO, BPA/DC and a bismaleimide [45]. Still higher heat resistance is achieved, if the poly-functional maleimide, based on aniline-formaldehyde condensation products (Scheme 11), is used [46]. [Pg.48]

To meet fabricated dimensional tolerances different approaches are used. They include use of specific fillers and reinforcements and process control (Chapter 3). Popular filler used is short glass fibers (Chapter 15). Over 50wt% of all types of glass fibers used with different plastics and by different processes are used in injection molding compounds. Table 2.2 shows the shrinkage of different unreinforced plastics ad glass fiber reinforced plastics based on ASTM testing procedures. [Pg.42]

FRP (glass fiber reinforced plastics) is widely used for auto parts, small-sized boats, bathtubs, etc. as a material with lightness, high strength, and durability. Its use is increasing yera by year, reaching nealy 500,000 tons per year at present. [Pg.99]

This particular manufacturer created a composite panel consisting of a glass-fiber reinforced plastic outer shell backed with a rigid polyurethane foam. The product looks like a cluster of hand split wood shakes. When installed, the panels interlock and look exactly like a shake shingle roof to the casual observer. These panels have been tested and qualify as a Class A built-up roof covering. In addition, they provide a much greater resistance to the transmission of heat than wood shake shingles. The panels are fast and easy to install and quite durable. [Pg.116]
