Concluding remarks

Abstract

Without any doubt, the theory is ambitious, but it is essentially not complicated, but straight forward and understandable for all design engineers. In general, composites are not “a” material, instead each laminate is an individually designed material. Such complex materials ask for an adequate theory which realistically covers the interaction of fibers and matrix. Having read this book, the reader will have found out that the Puck theory is in the form presented here very flexible and adaptable to experimental data and special material properties. The flexibility to be precisely adaptable to experimental data means on the other hand a lot of parameters. At first glance, this multiplicity of parameters adds to the first impression, that the Puck theory is complicated. However, with a very limited set of parameters which is not larger than for other theories, the Puck theory can be used. Moreover, for all parameters, reasonable values are given here. In other words, the user does not have to determine all parameters himself, but can use default values. As a conclusion I want to quote Alfred Puck saying that there is for sure no deficit of good theories, but instead a very obvious deficit of reliable experimental results. To overcome this still remaining deficit industry and scientific laboratories should work together all over the globe.
