Conclusions

  1. 1.

    A model is proposed with the aid of which it is possible to calculate the energy expended in the dynamic densification of sandwich type reinforced materials.

  2. 2.

    It is shown that the energy supplied in dynamic hot pressing is expended in driving the reinforcing fibers into the matrix material and in flattening matrix protuberances.

  3. 3.

    An equation is derived expressing the work of densification of a reinforced material as a function of the ductility properties of its matrix and the geometric parameters of the composite itself. An investigation has shown that results yielded by the relations derived in this work are in good agreement with experimental data.
