Now a day’s eco-friendly natural fiber used as the reinforcement for the fabrication of the light weight, lower cost and biodegradable polymer matrix composites. One of such available natural reinforcement for the composite material is basalt fiber. The present paper gives a review on how the basalt fiber reinforced polymer matrix composite behave when they are adhesively, riveted and hybrid joined with other reinforcements such as aluminum, which is used for the particular or other applications and which joint gives better efficiency , suited for given application were discussed and the three joining techniques were investigated. Behavior of basalt fiber reinforced composites for the frequencies at which frequencies the failures like adhesive failure, light fiber tear, and mixed failure modes will occur. These three types of failure modes are investigated with the help of acoustic emission monitoring system.

Optical Microscopy of Fiber-Reinforced Composites discusses the tools and techniques used to examine the microstructure of engineered composites and provides insights that can help improve the quality and performance of parts made from them. It begins with a review of fiber-reinforced polymer-matrix composites and their unique microstructure and morphology. It then explains how to prepare and mount test samples, how to assess lighting, illumination, and contrast needs, and how to use reagents to bring out different phases and areas of interest. It also presents the results of several studies that have been conducted using optical microscopy to gain a better understanding of processing effects, toughening approaches, defects and damage mechanisms, and structural variations. The book includes more than 180 full-color images along with clear and concise explanations of what they reveal about composite materials and processing methods.

In the recent years, due to environmental awareness of general public, researchers and scientists directed towards the use of natural fibers reinforced composites as environmentally friendly. Now a days, many scientists, researchers and engineers have explored the extraction, properties and utilization of natural fibers as economically and effectively as possible to produce good quality natural fiber reinforced polymer matrix composites. Many scientists and researchers proved that increase in fiber loading resulted in increased mechanical properties of the composite material. This will be the basis to develop and to evaluate properties of natural fiber reinforced polymer matrix composites. In this research, Kenaf long fiber reinforced epoxy matrix composites were successfully fabricated by simple and cost effective hand layup technique and their mechanical properties such as tensile strength, bending strength, impact strength, hardness with different fiber loading were successfully investigated. Water absorption capacity was also reported. The fibers are treated with NaoH solution for surface modification and to improve mechanical properties. The specimens are prepared according to ASTM standard and experiments were carried out
