As mentioned in the introduction, epoxide resin laminates are much less important in tonnage terms than those for polyesters. However, in terms of value the epoxide laminates are significant. 

Epoxide resin laminates are of particular importance in the aircraft industry. It has been stated that the Boeing 757 and 767 aircraft use 1800 kg of carbon fibre/ epoxide resin composites for structural purposes per aeroplane. The resin has also been used with Aramid fibres for filament-wound rocket motors and pressure vessels. The AV-18 fighter aircraft is also said to be 18% epoxide resin/cc bon fibre composite. The resins are also widely used both with fibres and with honeycomb structures for such parts as helicopter blades. 

TBBA, a brominated flame retardant, is used in the epoxy resin laminate in printed circuit boards in most manufacturers products. In 1997, a phosphorus-based alternative to TBBA was developed by the German engineering giant, Siemens,...

Microfabrication by means of laser radiation covers a wide range of different methods (24,25). On the one hand, these are processes where material is removed in an intense electromagnetic field by melting, evaporation, decomposition, photoablation, or a combination of these phenomena. On the other hand, generating processes exist where structures are built up from liquid resins, laminated layers, or powders using, e.g., photochemically induced crosslinking of organic compounds... 

Phosphate esters (alkyl or aryl, or mixed) of phosphoric acid constitute an important family of organophosphorus flame retardants.25 Triethylphosphate, a colorless liquid boiling between 209°C and 218°C, and containing 17 wt % phosphorus, has been used commercially as an additive for polyester resins/laminates and in cellulosics. In polyester resins, it functions as a viscosity depressant as well as a flame retardant. Trioctylphosphate is employed as a speciality flame-retardant plasticizer for vinyl composites where low temperature flexibility is critical. It can be also included in blends, along with general purpose plasticizers, such as phthalate esters, to improve low temperature flexibility.

As the submarine was too fragile to move, the only practical conservation method was to wash the vessel in situ. A tank was constructed from glass fibre - reinforced polyester resin laminate. The structure was prefabricated in sections away from the museum and assembled on site with no disturbance to...

Specimen geometry independence of the experimental measurement.s has been examined by, for instance, conducting DCB (mode I) and ENF (mode II) tests on specimens with different thicknesses [162. The values are virtually independent of thickness for CF epoxy resin laminates. A magnitude of increase comparable with the standard deviation... 

Du Font s Nafione membranes are perfluorinated ion exchange resins fabricated into reinforced and unreinforced membranes. Nafione Membrane 425, which we used in some of our tests, is a homogeneous film 5 mils thick of 1200 equivalent weight perfluorosulfonic acid resin laminated with T-12 fabric of Teflone TFE resin to make a 50 mil membrane. Properties and characteristics of Nafione membranes are given in reference 2.

Resin lamination should not be carried out at a temperature of less than 20C (68F). A catalyzed/promoted resin is heat-sensitive and catalyst levels should be adjusted to varying temperature as recommended by the manufacturer. With resin laminating, where space is limited, mold preparation such as releasing and gelcoating can be done in a tent made of polyethylene film (which can also be used as a warm area for curing resins in cold weather). 

As well as the materials and molds, resin lamination of all types needs a broad back-up of equipment for application and materials for cleaning. Many suppliers offer the full range and give useful comprehensive advice ...

Karasek et al. [66] conducted drop-weight impact tests on IM7 carbon fibre/ epoxy resin laminates after sea water exposure. Four resin systems (Table 7.2) were used, three of them being based on the same Shell Epikote 828 with different hardeners and/or impact modifiers. The volume fractions were in the range 60-69% fibre and the lay-up was [0/ 45/90°]js. Samples were about 6.35 mm thick for all materials (different cured ply thicknesses necessitated the use of differing numbers of plies) and cut to 100 x 100 mm squares for testing. The samples were saturated with ASTM D1141-52 Formula A synthetic sea water at 95°C, and then conditioned at ambient...
