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

Due to environmental reasons and their acceptable mechanical properties, natural fiber based polymer composites have been increasingly used in various applications, e.g. housing materials, automotive parts. However, their low thermal resistance and fire behavior limit the use of these materials. In this work, magnesium hydroxide (Mg(OH)2), as a flame retardant, was incorporated into sisal/polypropylene composites. Ratio of sisal fiber to Mg(OH)2 in each composite sample was varied. Maleic anhydride grafted polypropylene (MAPP) was also used to improve the interface of polypropylene and fillers. Flammability and thermal behavior of the composites were examined using a horizontal burning test and thermo gravimetric analyzer, respectively. Morphology and mechanical properties of the composites were also investigated.

Fiber Reinforced Polymer Composites

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.

In this study, multicomponent flame retardant systems, consisting of ammonium polyphosphate (APP), aluminum trihydroxide (ATH), and polyaniline (PANI), were used in ethylene propylene diene monomer (EPDM) rubber. The multicomponent system was designed to improve flame retardancy and the mechanical properties of the rubber compounds, while simultaneously reducing the amount of filler. PANI was applied at low loadings (7 phr) and combined with the phosphorous APP (21 phr) and the mineral flame retardant ATH (50 phr). A comprehensive study of six EPDM rubbers was carried out by systematically varying the fillers to explain the impact of multicomponent flame retardant systems on mechanical properties. The six EPDM materials were investigated via the UL 94, limiting oxygen index (LOI), FMVSS 302, glow wire tests, and the cone calorimeter, showing that multicomponent flame retardant systems led to improved fire performance. In cone calorimeter tests the EPDM/APP/ATH/PANI composite reduced the maximum average rate of heat emission (MARHE) to 142 kW·m−2, a value 50% lower than that for the unfilled EPDM rubber. Furthermore, the amount of phosphorus in the residues was quantified and the mode of action of the phosphorous flame retardant APP was explained. The data from the cone calorimeter were used to determine the protective layer effect of the multicomponent flame retardant systems in the EPDM compounds.

Abstract Natural Bast fiber reinforced polymer composites are attractive because of their renewability and environment friendliness. Therefore, in this work, the mechanical properties of these composites have been tried to improve by adding basalt fibers. The fiber mats were prepared by carding. After press molding, the tensile and Charpy mechanical properties of compression molded samples were studied. Moreover, the influence of basalt fibers with two different sizes was studied at the mechanical performance of the composites. Improvement of mechanical property profile of natural fiber (bast) reinforced polymer composites is carried out by hybridization with basalt fibers.
