The use of fiber reinforced polymer matrix composites (FRPCs) is in boom in many structural, industrial, automotive, and engineering applications. Polymer matrix composites have been turned out the most hopeful material which can replace the conventional materials, metals, and woods. Owing to this the demand for analyzing the tribological behavior of FRPCs is amplified. In the current article an inclusive literature survey on the tribological behavior of FRPCs in terms of friction and wear properties of composite materials is explored. The paper reviews the effects of different operating parameters and material parameters on wear rate and frictional behavior of FRPCs. The analysis reveals that operating parameters like sliding velocity, sliding distance, load, temperature and material parameters like a fiber volume fraction, orientation of fibers, fiber length, filler content, and effect of surface treatment have a significant effect on the tribological behavior of composite material. The wear rate of FRPCs is controlled by adding the proper amount of filler content and fiber orientation.

Interfacial interactions and interphases play a key role in all fiber reinforced composites. However, a clear distinction must be made between interface and interphase. Interphase becomes interface if its thickness decreases to zero. In most of the available micromechanical models the interface is considered perfect (no interphase). However, such a condition is hardly fulfilled in real composites. It is possible to find the volume of interphase by using DSC or identification of interphase region using SEM or some other sophisticated instrument techniques as it is a region created between the two main phase of a composite. All these techniques require special technical skill. In the present study attempt is made to identify the existence of the interphase region in fiber matrix composites using SEM. It was also decided to develop an equation for volume fraction and thickness of interphase by considering the composite as three-phase RVE. Developed equations of interphase volume fraction was used by considering the soft and stiff interphase parameters. Comparisons were made to study elastic behavior of fiber reinforced composites in longitudinal and transverse directions with available experimental data and published model in the literature and they are in good agreement.

Aluminum metal matrix composites have found applications in manufacturing of various components such as piston, cylinder block, and brake drum, in which wear and friction are important phenomenon. This paper presents an overview of diversified reinforcement on aluminum metal matrix composites in terms of tribological aspects. A comprehensive literature review is carried out on aluminum metal matrix composites based on individual reinforcement and multiple reinforcements including various product applications. The research review is summarized in form of tribology wheel for aluminum metal matrix composites, which encompass fields involved in tribology, fabrication processes/parameters, reinforcement(s) and matrix contribution, tribological testing parameter, statistical analytical technique, and product application areas of AMCs. The tribology wheel becomes helpful in selecting parameters with possible permutation and combination for further improvement of tribological properties. Finally, comments are addressed regarding the future work on tribological aspects of aluminum metal matrix composites.

India offered a biggest source of natural fiber like banana, rice husk, coconut and jute fiber etc. All the natural fiber has its unique advantages as well as mechanical properties which are very useful in the development of potential composites for various applications like transportation, automotive etc. There are various machining process in which drilling is most useful process for the assembly of different work pieces. During the drilling of composites it will undergo in the delamination process, which in turn reduces the strength as well as the efficiency of composites materials. In the present work drilling was carried out by using the various feeds (0.1, 0.2, 0.3 mm/rev), speeds (1000, 2000, 3000 rpm) and drill point angles (90 0 , 104 0 , 118 0) on the banana polyester reinforced composites. The delamination factor was measured by using machine vision system and digital image analysis. The mathematical model were developed using regression analysis to correlate the various machining parameters with the delamination factor and thrust force. Also the ANOVA has been used to found the effectiveness of the factors as well as their combinations. Optimization has been performed using the desirability function to find out the optimum machining condition for drilling of banana fibre reinforced composites.
