The mechanical properties of polypropylene/hemp fiber composites (fiber loading 30 wt%) at different compatilizer content were analyzed. The aim of the present work is to introduce natural hemp fiber as reinforcement in the preparation of partially biodegradable green composites. 1, p.120–128, (2012). Hemp plastic is a bio-based composite that may vary in composition and applications. This work is a contribution to the valorization, of plant fibers from agricultural plantations in Cameroon, in fiber cement mortar (FCM). Our purpose is to answer the question “what is hemp?” and bring industrial hemp, hemp education, CBD, hemp resources, and hemp products to the people and sustainability to the planet. The mechanical properties of composites with 15% wt fibers loading provided a 40% increase in strength. Natural fiber composites are designed for different purposes including structural and non-structural ones. Based on the experimental results and analysis, … Hemp composites work well in different ways – if water absorption and exuding is necessary, thermal and acoustic isolation, firmness and hardness. The defibrated hemp fibres had higher fibre stiffness (88-94 GPa) than hemp yarn (60 GPa), which the fibre twisting in hemp yarn explains. A number of hemp fiber surface treatments, used to improve the fiber/matrix interfacial bonding, have resulted in considerable improvements in the composites’ mechanical properties. Hemp is a subspecies of the cannabis plant; it lacks most of marijuana’s psychoactive effects, but can be used as raw material for several industries -such as textile and construction. The use of hemp fibers as reinforcement in composite materials has increased in recent years as a response to the increasing demand for developing biodegradable, sustainable, and recyclable materials. Art. In 1941, hemp fibers (and flax) were used in resin matrix composites for the bodywork of a Henry Ford car which was able to withstand ten-times the impact on an equivalent metal panel. The results show that, the thermal conductivity of composites increases linearly with density. However their biggest disadvantage is the variability in their properties. This core is high in silica content making it able to bind very well with lime, a rare quality among plant-based material. Hemp fiber is one of the dominant classes of bast natural fibers, commonly procured from the hemp plant with the species of Cannabis. fiber polypropylene composites, formulations containing 25% and 40% (by weight) hemp fiber were produced and tested at three representative temperatures of 256, 296, and 336 K. Flexural, tensile, and impact tests, as well as dynamic mechanical analysis, were performed and the reduction Mechanical and Thermal Properties of Hemp Fiber-Unsaturated Polyester Composites Toughened by Butyl Methacrylate Tianshun Xie,a Wendi Liu,a Tingting Chen,a and Renhui Qiu b,* Hemp fiber-reinforced unsaturated polyester (UPE) composites were prepared by hand lay-up compression molding. Composites made of hemp fibers with thermoplastic, thermoset, and biodegradable matrices have exhibited good mechanical properties. It has been observed that, in both cases, hybrid composites showed improved mechanical properties when compared to the individual fiber composites. This study aims to evaluate the resistance in tensile tests of epoxies composites reinforced with different percentages of hemp fiber.
