Wu et al. [115] were the first to demonstrate the effectiveness of this technique in manufacturing all-composite sandwich cylindrical shells with pyramid-like lattice cores. The entire manufacturing process consists of two steps. They created an outer laminated skin stiffened with a lattice core in the first step.
Blast Furnace Steel Production Process. A blast furnace is a huge steel roughly cylindrical shell lined with heat-resistant brick. Steel production in a blast furnace is a continuous process. Hence, once steel manufacturing started, the production continues for years until the refractory lining is damaged or demand dropped.

— In the pultrusion process, wet fiber is pulled thorough a shaped die that is really hot. The fiber and resin goes in one end all goopy and comes out a fully cured part. Like extrusion (which is a push process), pultrusion (a pull process – can't push on wet fiberglass!) produces long things with a consistent sectional shape.
