| Knitted multiaxial reinforcement are today more and more commonly used in the production of marine vessels. This is due to superior strength compared to traditional reinforcements such as woven roving and chopped strand mat. Strength properties in different resins are documented, and multiaxial and woven reinforcements are compared. Special attention is paid to interlaminar properties, and it is apparent that no intermediate layers of chopped strand mat are necessary when using multiaxial reinforcement. Methods of analysis are discussed, the influence of fibre orientation on strength and stiffness of structures is described, and a case study reveals considerable weight and cost saving potential. |
