Fiberglass Cloths

Consumption of unsaturated polyesters in the marine industry consists of broad usage for hulls, decks and numerous small parts such as hatch and engine covers. Hulls and decks are generally produced with unsaturated polyester resins and multiple layers of fiberglass cloth knits and chopped fibers. Most marine applications require the use of unsaturated polyester resin gel coats for exterior appearance and for protection from the elements. 

Heat-cleaned fiberglass cloth was treated with 0.5% carboxysilane J (Table 1) and compression-molded into a laminate with nylon 6,6 polymer. Laminates were compared to state-of-the-art silane H. Table 9 shows that silane H provided a significant improvement in flexural strength over the control, expecially after a 2 h water boil, but a carboxysilane/zinc ion ionomer system gave an even better strength improvement. 

These new composites are stronger than the old polyester resin/"E" type fiberglass cloth laminates. 

Unlike the simple ceramic tiles outlined in Section III-A ( 3),a fiberglass cloth/ceramic composite will absorb repeated hits without breaking up or deteriorating. Armor panels can be produced in both standardized flat rectangular sheets and as custom contoured pieces for installation in quarter panels,roof pillars, curved floors etc. 

The only unique aspect of this type of ceramic work is the addition of chopped strands or small strips of fiberglass cloth to the wet clay body. This can be done with a rolling pin for flat or "slab"... 

Note This process uses FIBERGLASS CLOTH ONLY - not the companion plastic resins or catalysts. Also note that Kevlar nylon and other similar fabrics cannot he used because of their low melting points. 

Catalyst particles enclosed in bales Catalysts are loaded in pockets sewn into a fiberglass cloth. The resulting belt or catalyst quilt is rolled with layers of steel mesh to form a cylinder of catalyst bales, which are piled up to the required height. After the catalyst... 

In cases requiring crack sealing, one can proceed as shown in Figure 7.18. After the respective surface treatment, a precut part made of characteristic material is glued over the damaged spot. To reinforce the adhesive layer, fiberglass cloth can be included by laminating. Round components require the prior... 

Although FEP is available as a liquid dispersion, the commonly used material in liquid dispersion coatings are PFA and PVDF. Both materials are used in various ways such as filled or unfilled. T q)ical fillers for PFA are mica flakes. PVDF can be reinforced with fiberglass cloth or carbon fabric for additional permeation protection. T q)ical thicknesses achieved are up to 80 milli-inches (2 mm). PFA coatings are used with wire mesh reinforcment for additional protection from delamination.

The loss of three-dimensionality in the higher temperature regime is not a consequence of internal sample geometry—the fibers are macroscopic. For example, the specific heat of the boron/aluminum composite contains the cubic term and conforms to the mixture principle for bulk metallic ingredients. Moreover, experiments performed previously and discussed elsewhere [ ] demonstrate the dominance of a quadratic term in the low-temperature specific heat of a fiberglass-cloth-reinforced resin. The tendency to lower-order dimensionality is presumably a property of the lattice dynamics of the polymeric chains and rings characteristic of the resin matrix.

CEM-3, a composite of dissimilar core materials, uses an epoxy resin impregnated, non-woven fiberglass core with epoxy resin impregnated, woven fiberglass cloth surface sheets. It is higher in cost than CEM-1, but is more suitable for plated through holes. CEM-3 has been used in early home computers, automobiles, and home entertainment products. 

FR-4, by far the most commonly used material for printed circuits, is constructed of woven fiberglass cloths impregnated with an epoxy resin or epoxy resin blend. The outstanding electrical, mechanical, and thermal properties of FR-4 have made it an excellent material for a wide range of applications including computers and peripherals, servers and storage networks, telecommunications, aerospace, industrial controls, and automotive applications. FR-4 will be discussed in more detail later.

Over the years, continuous lamination processes have also been designed. Rather than cut the prepregs and foils into sheets, lay them up and press them as individual laminates, these processes use rolls of prepreg or bare fiberglass cloth and rolls of copper foil that are continuously unwound and fed together into a continuous horizontal press. One process starts with rolls of prepreg. Another starts with the bare, untreated fiber ass cloth, applies a resin to the cloth and is sandwiched with the copper foil as it is fed continuously into a horizontal press. At the back end of the press, sections of the continuous laminate can be cut into sheets, or with thin laminates, rolls of copper clad laminate can be manufactured.
