Fiberglass-epoxy

Note also that the aft tip of the wedge was filled with a fiberglass/epoxy wedge. This strengthened the tip and makes it more resistant to delamination. 

Typical stress-strain curves are shown for the commonly used fiber-reinforced materials fiberglass-epoxy, boron-epoxy, and a representative graphite-epoxy. These curves are not accurate enough for design use ... 

The curves for 3M XP251S fiberglass-epoxy are shown in Figures C-1 through C-5 [C-1]. Curves are given for both tensile and compressive behavior of the direct stresses. Note that the behavior in the fiber direction is essentially linear in both tension and compression. Transverse to the fiber direction, the behavior is nearly linear in tension, but very nonlinear in compression. The shear stress-strain curve is highly nonlinear. The Poisson s ratios (not shown) are essentially constant with values v.,2 =. 25 and V21 =. 09.

To substantiate the confidence level on our empirical data, data simulation using thermal modeling was exercised. The classical diffusion equation and the following parameters were utilized The thermal conductivity of copper is 3.88 watts/ C-cm whereas that of the Fiberglass/epoxy is 0.0028 watts/ C-cm. The heat capacity (Cp) of copper is 0.09213 cal/ C-g whereas that of the Fiberglass/epoxy composite is 0.22 (30 Cp) and 0.43 cal/ C-g (120 Cp).

The electrical insulation properties of LCP are excellent, and because the LCP is homogeneous material, it is not prone to void formation as in fiberglass epoxy composite. The electrical breakdown strength of LCP is higher than polycarbonate—a plastic that is well-known for its good electrical properties. 

The term composite, as used in this paper, refers to materials having overall properties that are some average of the properties of several distinct components, one of which is contiguous and forms a matrix having a noncoherent interface with the reinforcing elements. Filamentary-reinforced materials, such as fiberglass-epoxy, and aggregates, such as concrete, fall within this definition. Composite laminates are built up from distinct plies of reinforcement in contrast to filament-would composites, which do not exhibit a laminated structure. 

Armor Plate (Texas, US) is another pipe repair system that uses multipurpose fiberglass/epoxy wraps and different curing agents (see Fig. 18.11). The difference between Armor Plate and StrongBack composite repair systems (discussed below) is that Armor Plate uses chemicals instead of water as the catalyst agent.
