5.1 The hull formed by the mold is based on the mold surface as the theoretical line. 5.2 The upper surface of the deck, platform and other horizontal plates is the theoretical line. Surface
Reinforcement material is glass fiber or its products
Non-woven glass fiber products with a felt appearance, in which randomly evenly distributed short-cut glass fibers are fixed with a binder. Non-ball glass fiber cloth woven from glass fiber non-painted roving has a thixotropic resin layer with decorative and protective functions on the surface of FRP products
Polyvinyl chloride foam plastic
Polyurethane foam plastic
Short-cut glass fibers are fixed with a binder, a very thin glass fiber mat
5.3 The theoretical line of the frame of symmetrical sections (such as trapezoidal, rectangular and semicircular) is the center line of its section. 5.4 The theoretical line of the frame of asymmetrical sections (such as angle materials) is the back edge of the folded edge. 5.5 The theoretical line of the longitudinal bulkhead plate of a single-plate structure is taken on the side close to the center line of the hull. The theoretical line of the transverse bulkhead plate of a single-plate structure is taken on the side close to the ship. bzxZ.net
5.6 For the longitudinal and transverse bulkhead plates and perimeter plates of the sandwich structure, the center line of their plate thickness is taken as the theoretical line. 5.7 For an example of a diagram, see Figure 1.
