Tenting frame process

It is interesting to frame these very tentative considerations in terms of rod diffusion, since this is the process by which the polymer-rich phase must be formed. However, care must be taken to isolate the effects of mutual diffusion of the collection of rods as a (phenomenological) response to a concentration (chemical potential) gradient and simple self diffusion of a single rod, which is the case treated by Doi and Edwards.(24)... 

To date, the process has penetrated the application areas such as land transport, construction, infrastructure, electrical, marine and offshore, and aerospace. With the introduction of newer technologies, pultrusion can be used to produce nearly any constant cross-sectional shape (Meyer, 1985) such as channels, tubes, beams, bars and many other profiles for handrails, ladders, cable ducts, antennae, rail covers, tent poles, hockey sticks, fishing rods, pipes, slide guides, luggage racks, leaf springs, window frames, farm wagons, bridge sections, roof profiles, etc.
