Fiber reinforced polymer (FRP) composite materials are widely used in advanced structures and replacing traditional materials at a growing pace. In addition to lighter structure made from these materials, their potential in the production of novel tailor-made materials with properties and performance far beyond those of the traditional materials make them a superior alternative.

During the last decade FRP composite materials have been successfully deployed in aerospace, automotive, and renewable industry and beyond. In all of these FRP applications, impacts may occur in various stages of manufacturing, normal operation, and maintenance and could severely reduce the structural strength and durability. The impact and post impact behavior of FRP materials is complex, and identification of the resulting damage due to impact often appears in the form of delaminations, matrix cracking and fiber failure is of great interest. As a result the research in this area is very active and ongoing.

This special issue focuses on the use of FRP composite materials in a broad range of applications related to aerospace, automotive, renewable energy (wind turbine blade), and sport equipments. You are invited to contribute original research as well as review articles dealing with the impact and post impact behavior of FRP composite and sandwich structures. Submitted papers can cover both low velocity and ballistic impact.

Research of the relationships between the structure and properties of matter are the traditional problem of the science of materials. Understanding of the material as a complex system, attention to the specific characteristics of many-sided cooperation variously-scaled structures, expands the possibilities of purposeful changes of the structure of the material in order to obtain new properties.
Modern research has shown the essential role played by specific objects intermediate asymptotics - clusters - in shaping the properties of the material. As it is known, the percolation clusters substantially alter the processes of conduction, lead to the anomalous diffusion, determine the mechanical strength and corrosion resistance, impact on longevity, can lead to the occurrence of second order phase transition, and transformation of other physical, chemical and mechanical properties.
The aim of this special issue is to demonstrate of the recent advances in area of interdisciplinary research of the composite materials.
