Fatigue strength evaluation of PPGF35 by energy approach during mechanical tests

Thanks to the progress of research on thermoplastic materials, the properties of composite materials have improved considerably. The aim of this study is the evaluation of fatigue strength of glass-fibre-reinforced polypropylene composite (PPGF35) by applying both the Risitano Thermographic Method (RTM) and the new Static Thermographic Method (STM).

Features of Contact Interaction of Anti-Friction-Wear-Resistant Polypropylene Composite Materials with Raw Cotton

Based on the concepts of the theory of interaction and research in the course of researching the process of studying the interaction of composite polymer materials using the method of modeling interaction - the mechano-electric theory of contact interaction. The proposed formula for determining the coefficient of friction of composite polymer materials using pulp (raw cotton).
