Bending stress of birch, palm and eucalyptus reinforced epoxy composites were found as 58.83, 68.58, and 79.92 MPa, respectively. The birch epoxy composite had 0.105 J impact energy while palm and eucalyptus epoxy composites were determined as 0.130 and 0.124 J, respectively. It is clearly observed that fiber type was very effective on mechanical properties of composites. The results of studies showed that molded fiber production method had a very promising future for the development of natural fiber reinforced composites.

Materials Today: Proceedings, 2017
Most of the developing countries are very rich in agricultural and natural fibres. It has got a very large percentage of production of rice husk, jute, stalk, baggase and coconut fibre in India. All these natural fibers have excellent physical and mechanical properties and can be utilized more effectively in the development of composite materials for various industrial applications. The present study deals with the effects of natural fibers on some mechanical properties of the Epoxy composites. This research was carried out by reinforcing the matrix (Epoxy) resin with natural fibre (cane sugar fibers) and glass fiber. The natural fibers were exposed to chemical treatment before reinforcement. The hybrid composites reinforced with chopped glass and cane sugar fibers were produced using hand layup method. Each sample was fabricated with different 10, 20, and 30 percent by volume of sugar cane fiber. After preparation of composite material, the mechanical properties like flexural and impact strength were studied. Cane sugar fibre composites were found to have the higher values of flexural strength (490.77 MPa) and impact strength 93.92 KJ/m 2) than chopped glass fiber composites (flexural strength 93.19 MPa and impact strength (23.92 KJ/m 2). It was found that the addition of natural fibers (cane sugar) along with chopped glass fibers improve the mechanical properties of hybrid composites.

Study on Mechanical Behaviour of Carbon Fiber Reinforced Epoxy Composites
TJPRC, 2013
Fiber-reinforced polymer composites have played a dominant role for a long time in a variety of applications for their high specific strength and modulus. The fiber which serves as a reinforcement in reinforced plastics may be synthetic or natural. Past studies show that only natural fibers such as bamboo, jute, coconut etc., have been used in fiber-reinforced plastics. Although glass and other synthetic fiber reinforced plastics possess high specific strength, their fields of application are very limited because of their inherent higher cost of production. In this connection, an investigation has been carried out to make use of carbon, a synthetic fiber. The present work describes the development and characterization of a new set of synthetic fiber based polymer composites consisting of carbon as reinforcement and epoxy developed composites are characterized with respect to their mechanical characteristics. Experiments are carried out to study the effect of fiber weights on mechanical behavior of these composites. In the present work, carbon composites are developed and their mechanical properties are evaluated.
Mechanical Performance of Modified Epoxy Reinforced Hybrid Natural Fiber Composite
Jurnal Teknologi, 2015
Kenaf fiber that is known as Hibiscus cannabinus, L. family Malvaceae is an herbaceous plant that can be grown under a wide range of weather conditions. The usage of kenaf fibers as a reinforcement material in the polymeric matrix has been widely investigated. In this research, liquid epoxidized natural rubber (LENR) was introduced to the epoxy to increase its toughness. Hybrid kenaf/carbon fibers, with different kenaf/carbon ratio weight, were used to reinforce the epoxy resins (with and without addition of epoxidized natural rubber) as the matrices. The flexural strength, flexural modulus and fracture toughness of the rubber toughened epoxy reinforced hybrid kenaf/carbon fiber composites were investigated. The results showed that the addition of liquid epoxidized natural rubber (LENR) had improved the flexural strength, flexural modulus and fracture toughness by 9.6%, 13.7%, and less 2% respectively at the ratio of 16:4 wt% fibre loading

Hybrid polymer composite were prepared by incorporating two indigenous agro-industrial waste reinforcements, sugarcane bagasse fiber (SBF) and coconut coir fiber (CCF) into epoxy resin through the hand lay-up technique. Nano-silica was also added to enhance the mechanical performance of composite materials. The alkaline treatment on the surface of natural fibers was carried out and its effects on the mechanical properties were investigated. Generally, it is found that the CCF reinforced epoxy composites exhibited higher mechanical properties as compared to the SBF reinforced epoxy composites. For hybrid composite samples, (2.5wt%SBF+12.5wt%CCF) had attained the highest mechanical performance amongst all other different ratio percentage of hybrid polymer composite.
