Foreword

GB/T 19314 "Small boat hull structure and component size" is divided into 9 parts.

--- Part 1. Materials. thermosetting resins, glass fiber reinforced plastics, reference laminates;

--- Part 2. Materials. core materials for embedded structures, embedded materials;

--- Part 3. Materials. steel, aluminum alloy, wood, other materials;

--- Part 4. Workshop and manufacturing;

--- Part 5. Determination of design pressure, design stress and component size of single vessel;

--- Part 6. Structural arrangements and details;

--- Part 7. Determination of the dimensions of multi-hull ship components;

--- Part 8. Rudder;

--- Part 9. Sailboat possession.

This part is the second part of GB/T 19314.

This part is drafted in accordance with the rules given in GB/T 1.1-2009.

This section uses the translation method equivalent to ISO 12215-2.2002 "Small boat hull structure and component dimensions Part 2. Materials. clamps

1 Scope

This part of GB/T 19314 applies to structural core materials and materials embedded in sandwich structures. This section applies to ISO 8666

A dinghy with a specified hull length (LH) of no more than 24 m.

Note. The root cause of this part of GB/T 19314 is that the sandwich structure of the boat requires careful selection of the core material from many materials and must be pressed.

The column is programmed to achieve a predetermined long-term service life under expected load and environmental conditions.
