| 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. |

| The material properties of over 50 different laminates made by a group of Finnish boat-yards have been measured in a large test project. Tension, compression, bending, interlaminar shear and impact tests have been carried out for all the laminates. Among others, different polyester resins, different woven and non-woven fabrics, chopped strand mat and unidirectional roving were used as basic ply materials. The effect of various parameters has been determined not only on the maximum failure strength, but also on the strain level at which the first failure occurs. Main differences between the ratio of static and impact test results of the different materials have been determined. The results show that by choosing certain material parameters efficiently,... |
