Mechanical properties of Roselle fiber reinforced vinyl ester biocomposite were studied based on the fiber content and length in the present communication. Usually, natural fiber reinforced polymer composites depend on some aspects such as fiber content, fiber length and orientation, the fiber-matrix adhesion. Composite plates were prepared by a simple hand lay-up technique for two different fiber lengths (3 and 13 mm) and five different fiber content (10, 20, 30, 40 and 50 wt%). Composite specimens were tested according to ASTM standards and their results were recorded. Experimental results showed that mechanical properties such as tensile, flexural and impact, increases with increase of fiber content up to 40 wt% after which it is decreases at both the fiber length. However, modulus values were increased linearly with fiber content of 10 to 50 wt%. Composites with the fiber length of 13 mm show the high level of mechanical properties compared to composites with the fiber length of 3 mm at all combinations of fiber contents. It is observed that the optimal fiber content is 40 wt%, which can be used to obtain the maximum property level in the Roselle fiber reinforced vinyl ester composites

Using PMMA Polymer reinforced by Natural Fiber (N.F.) materials have established much consideration because of several advantages for example low cost, non-abrasive, lightweight, non-toxic and the properties of bio-degradable. many kinds of research have been done in the recent usage of the natural reinforcing material to the preparation of different types of composites. Chemically treated jute fiber can enhance the surface of the fiber, decrease the absorption technique, and improve the roughness surface.in this research, pre-chemical treated in different lengths of jute- fibers in PMMA polymer-composites has been considered. Also, the effect of chemical treatment on mechanical properties of jute, jute reinforcing composite has been conferred. The results showed that the tensile strength T.S. of the treated in benzoylate solutions (4 mm) length fiber had good indicate to better interlocking between composite contents.Flexural-Strength F.S. of the-alkaline. solution treated (12 mm) length of fiber was obtained-better-results by increasing (16.5 %) compared with (2 mm) fiber-length. The fracture of the samples has discussed the relationship between composite adhesion. Impact Strength I.S. of the alkaline-treated (8,12 mm) fiber- a length that is due to to.better mechanical - interlocking between composite materials. The 2 mm fiber – length was not suitable-PMMA/ Jute composite in these tested for treated and untreated chemicals

Recently, natural fiber reinforced polymer composites have become popular over traditional synthetic fiber reinforced polymer composites for automotive, low demanding structural and semi-structural applications. In this work, a comparative study of a natural fiber composite such as jute fabric composite (JFRP) and synthetic fiber composite such as glass fiber composite (GFRP) is presented. The composites were manufactured using hand lay-up and then curing at 90°C for 10 min in a hot press, followed by 24 h room temperature post-curing. The mechanical properties such as tensile and bending of JFRP and GFRP composites, were evaluated and compared. It was revealed that even if GFRPs exhibited significantly higher mechanical properties than JFRPs, environmental impact would still favor JFRPs for non-structural and low load bearing applications.

Fiber Reinforced Polymer Composites

In the last decade, natural plant fibers (jute, sisal, coir, banana, hemp, kenaf, flax, etc.) are getting attention from many researchers and academicians to utilize it as an alternate reinforcement of synthetic fiber reinforced polymer composites. These fibers are becoming a great replacement of conventional fibers (such as glass, carbon, and aramid) due to their light weight, low cost, carbon neutrality, fairly good mechanical properties, high specific strength, and biodegradability characteristics. Some chemical treatments are required to enhance the fiber matrix interfacial strength and to minimize the moisture absorption by these fibers which would ultimately improve physico-mechanical properties of these fiber reinforced composites. This paper is a review on mechanical properties of the natural plant fiber reinforced polymer composites and various factors affecting the mechanical performance of it. The tribological behavior of natural fiber reinforced polymer composites and scanning electron microscope analysis are also discussed. Some mathematical models are mentioned which are useful to predict mechanical behavior of the composites. It is found that Halpin–Tsai equation is the most effective equation amongst others in predicting Young’s modulus for short-fiber reinforced composites with minimum error. The applications of natural plant fiber reinforced polymer composites in various engineering fields are discussed.

The natural fiber–reinforced polymer composites gaining substantial importance in recent years due to their unique properties compared to synthetic composites. In India (especially northeastern part), cultivars and industries mostly focus on pineapple fruits, leaving leaf to mainly compost or burn and decay as an agro waste. In this article, pineapple leaf–based (variety type Kew or Giant Kew from Silchar, Assam, India) short fiber–reinforced polymer composites as a function of fiber composition and composite thickness on mechanical properties are analyzed. In this regard, short pineapple leaf fibers (≈ 1 mm to 2 mm) as reinforcement + epoxy resin (Lapox (L12) resin + K6 hardener) as matrix material are used for composites. Subsequently, six different fiber compositions (as 0, 1, 5, 10, 15, and 20 wt%) with composite specimen’s thickness (as 3 and 5 mm) are prepaid. Later, mechanical properties like tensile strength, flexural strength, and toughness and hardness values for each of the composite specimens are evaluated. The result shows that the addition of short fiber can improve the mechanical properties and found in all the cases composites with 10% of reinforcement + at 5-mm thickness show better performance than the other combinations.
