Glass-filled epoxy

In Figure 5.24 the predicted direct stress distributions for a glass-filled epoxy resin under unconstrained conditions for both pha.ses are shown. The material parameters used in this calculation are elasticity modulus and Poisson s ratio of (3.01 GPa, 0.35) for the epoxy matrix and (76.0 GPa, 0.21) for glass spheres, respectively. According to this result the position of maximum stress concentration is almost directly above the pole of the spherical particle. Therefore for a...

Though the majority of printed circuit boards (PCBs) at present are two-dimensional and made of glass-filled epoxy resins, increasing miniaturization has led to more PCBs being multi-layered with several copper circuits sandwiched between insulating layers. In these applications, because of the added stress due to thermal expansion, specialty materials such as polyamides and fluoropolymers have been increasingly used.

Lined carbon steel is the standard material of construction for primary pressure filter vessels. Typical linings are hard rubber, 3 or 6 mm thick, and glass-filled epoxy resins. Metallic internals tend to be Monel or titanium. Piping is FRP or a thermoplastic such as PVC wrapped with FRP for reinforcement. Internal piping, if not metal, may be of CPVC, properly supported. In larger sizes, support plates usually are of rubber-coated steel.

The absorption of water is greater in the cheaper cellulose-filled phenolic boards than in the more expensive glass-filled epoxy boards. Nevertheless, modern boards of both types are now fabricated with surface treatment of the filler to minimise rater absorption.
