As with tissue, woven glass cloth is used for decorative or acoustic purposes. Additionally, close-woven fabrics give improved fire-safety properties and are resistant to mechanical abuse. Glass cloth or scrim of an extremely open weave is used on insulants as a key for mastic or hard-setting finishes. 

The results described in this paper were all obtained from tests on E-glass reinforced composite materials produced by hand lay-up. This is the manufacturing route most frequently used for marine structures. For the majority of the tests reported here the E-glass fibres were either quasi-unidirectional (250 g/m with 1 g/m of polyester fibres bonded in the 90° direction to keep the UD fibres in place) or stitched quadrlaxial (0/45/907-45° 1034 g/m ) cloths. The same uniaxial ply is used in both cloths. The resin is based on DGEBA epoxy (SRI500) with an amine hardener (2505) from Sicomin, France. All epoxy specimens were post-cured at 90°C for 6 hours. Some results are also shown for a woven glass (0/90° 500 g/m ) reinforced isophthalic polyester for comparison, as this is the traditional marine...

One can think of the PTFE dispersion coating process as impregnation of fibrous or porous materials such as glass fiber, woven glass cloth, and polyaramide fibers and fabrics. The composite product combines the properties of PTFE and substrate. The polytetrafluoroethylene coated or impregnated products are characterized by a number of common attributes, Table 5.9.

The blade has a true composite construction, as shown in Figure 8.27, with areas of unidirectional glass and carbon fibre, woven glass cloth trailing edge skins laid at 45 over a polyaramid paper honeycomb core, and a titanium erosion shield. The polymeric matrix for the fibres is epo) resin. The metal blades that it replaces were retired after 9400 hours in service, whereas the composite blades do not need replacement during the 40000 hour life of the airframe. Safety is improved, and overall running costs reduced.

Polymerization of pyrrole has also been carried out chemically by mixing the monomer with a homogeneous oxidant (Fe ) in solution. Mermillod et al [61] found that poly(pyrrole) synthesized in water by action of Fe ( 104)3 produces particles in solution as well as films on the reactor walls. The material was electrochemically identical with electropolymerized product. Gregory et al [62] chemically deposited very uniform films of poly(pyrrole) on textile fibres and woven glass cloth. Gottesfeld et al [63] found that chemically deposited films were uniform and could serve as a conducting substrate for metallization structures for microelectronic circuitry. Hillman et al [64] studied the electrodeposition of poly(vinylfer-rocene) with the quartz crystal microbalance. 

Improved chemical resistance can be achieved by the use of a thermoplastic or synthetic rubber liner. If the liner is sufficiently rigid it can be supported on a light frame and used as the mandrel, if not then it can be wrapped round the mandrel first. A grade of polypropylene is available which has a woven glass cloth partially rolled into one side to improve adhesion of the resin system (Celmar).
