The 1980s saw the removal of large quantities of asbestos (qv) from buildings, creating the need for clothing which could not be penetrated by small asbestos fibrils, yet was iaexpensive enough to permit daily disposal. Certain spunbonded and spunbond/meltblown laminate fabrics demonstrate excellent resistance to asbestos penetration from particles as small as 0.5 p.m (70). 

Glass fibres are the preferred form of reinforcement for polyester resins since they provide the strongest laminates. Fabrics from other fibres may, however, be used and can in some instances provide adequate reinforcement at lower cost. Glass fibres are available in a number of forms, of which the following are the most important ... 

Coated and laminated fabrics (the original application for THV resins) are used in many fabric applications where flexibility, weatherability, and/or low permeability are required. 

The range of applications includes sealing cartons, bonding packaging films and laminates, fabrications for the motor industry, and applying veneers to chipboard and plywood.

The triclosan-(5-CD-IC was formed and small amounts were mixed with PCL powder, which was sprinkled onto cotton fabric and then covered with another piece of cotton fabric. The cotton-PCL/triclosan-( -CD-IC-cotton was ironed into a laminate, placed on an Agar plate, and then tested against the growth of E. coli bacteria. As can be seen from the test results in Table 5, E. coli bacteria were unable to grow upon the laminated cotton fabric containing triclosan-(i-CD-IC. In fact the laminated fabric was just as effective as films of PCL containing triclosan-P-CD-IC or pure triclosan. 

Coated and laminated textiles usually consist of a textile substrate, which will typically be a woven, knitted or nonwoven fabric, combined with a thin, flexible fdm composed of a natural or synthetic polymeric substance. A coated fabric is one in which the textile substrate has a polymer film applied directly to one or both surfaces as a viscous liquid in a solvent or water, the thickness of which is controlled by application via a blade or similar aperture. A transfer coated fabric is an intermediate product in which a thermoplastic film is first prepared on a release paper prior to thermally bonding to the textile substrate. A laminated fabric usually consists of one or more textile substrates that are combined with a pre-prepared polymer film or membrane by adhesives or heat and pressure (Hall, 2000).

A four-ply graphite cloth laminate based on polymer (e) was fabricated. Limiting oxygen index of this laminate was determined according to ASTM D2863-74 and was found to be 71%. Similar values for the graphite cloth laminates fabricated from 9,9-bis(p-maleimidophenyl)fluorene have been obtained earlier (2). 

Figure 8.25 shows an operator working on laminate fabrication. Figures 8.26 and 8.27 illustrate the fabrication technique and examples of dual laminate structures. The job sequence is as follows ... 

Many combinations of resins and reinforcement types and weaves available for specific structural applications. Directional strength properties can be varied from unidirectional to orthotropic by choice of reinforcement type and laminate fabrication method. 

Clearly, the mechanical properties of woven fabric-reinforced composites are dominated by the type of fibre used, the weaving parameters, and the stacking and orientation of the various layers. However, there are additional subtleties which also affect composite performance. For example, some authors have noted the possibility of slightly altered mechanical properties depending on whether the yams are twisted prior to weaving in addition, damage accumulation under static and cyclic loading is different in laminates fabricated from twisted or untwisted yam.
