Polypropylene is an extremely versatile thermoplastic polymer known for its good performance/price ratio, ex-cellent heat, moisture and chemical resistance, favorable processing characteristics and recyclability. Due to its uni-versal properties, polypropylene is applied in numerous industrial fields such as electronic and electrical, automobile, textile, pipeline, etc. Furthermore, the progress in its synthesis and property modification in the last decade has con-tributed to the development of new polypropylene based materials with advanced performance. This review aims at reporting on some recent developments in polypropylene based materials, such as nanofibers, natural fiber reinforced composites, self-reinforced polypropylene and polypropylene/clay hybrids, that have replaced many types of engi-neering thermoplastics in high-performance applications.

Abstract Like synthetic fiber reinforced composites, natural fiber reinforced composites possess a good potential to be used in high performance applications due to their good balance of mechanical and damping properties. Composite materials used in sporting goods equipment and automotive applications are subjected to repeating, regular loads. Therefore a clear understanding about the reliability of composite materials under fatigue/cyclic loading is important for their design in high performance applications. Currently, the fatigue performance of natural fiber reinforced composites are not well understood or characterized. The fatigue damage of flax fiber reinforced polymer matrix composites can be divided into two components: thermal damage due to self-heating in the sample and micro-mechanical damage due to damage creation (i.e. crack initiation, crack propagation, delamination, etc.). In this study, fatigue tests were conducted at four different loading frequencies and the two energy components defined were separated experimentally. The fatigue life of flax fiber reinforced composites was found to decrease with increasing loading frequency. Thermal damage due to the high self-heating temperature of the sample was found to be the main responsible form of energy which decreases fatigue life with increasing loading frequency. Micro-mechanical damage due to cyclic loading was not found to change significantly with increasing loading frequency.

Background: This era has seen outstanding achievements in materials science through the advances in natural fiber-based composites. The new environmentally friendly and sustainability concerns have imposed the chemists, biologists, researchers, engineers, and scientists to discover the engineering and structural applications of natural fiber reinforced composites. Objective: To present a comprehensive evaluation of information from 2000 to 2018 in United States patents in the field of natural fibers and their composite materials. Methods: The patent data have been taken from the external links of US patents such as IFI CLAIMS Patent Services, USPTO, USPTO Assignment, Espacenet, Global Dossier, and Discuss. Results: The present world scenario demands the usage of natural fibers from agricultural and forest byproducts as a reinforcement material for fiber reinforced composites. Natural fibers can be easily extracted from plants and animals. Recently natural fiber in nanoscale is preferred over micro and macro scale fibers due to its superior thermo-mechanical properties. However, the choice of macro, micro, and nanofibers depends on their applications. Conclusion: This document presents a comprehensive evaluation of information from 2000 to 2018 in United States patents in the field of natural fibers and their composite materials.

In the recent years natural fiber reinforced composites are increasingly receiving attention from the researchers and engineers due to their mechanical properties comparable to the conventional synthetic fibers and due to their ease of preparation, low cost and density, eco-friendliness and bio-degradability. Natural fibers such as kenaf or flux are being considered as a viable replacement for glass, aramid or carbon. Extensive experimental studies have been carried out to determine the mechanical behavior of different natural fiber types such as the elastic modulus, tensile strength, flexural strength and the Poisson’s ratio. This paper presents a review of the various experimental studies in the field of fiber reinforced composites while summarizing the research outcome about the elastic properties of the major types of natural fiber reinforced composites. Furthermore, the performance of a kenaf reinforced composite plate is demonstrated using finite element analysis and results are compared to a glass fiber reinforced laminated composite plate.
