Comparative mechanical properties between biocomposites of Epoxy and polyester matrices reinforced by hemp fiber

Journal of Materials Research and Technology, 2020
Natural fibers have, in past decades, been increasingly used as reinforcement of polymer matrix composites in substitution for synthetic fibers. This work presents a comparative study on the mechanical properties of both epoxy and polyester composites ...

Pricing Dynamics in the US Hemp Market: A Vertical Price Transmission Analysis of the Hemp Value Chain

Agribusiness, EarlyView.
ABSTRACT The US hemp market is a new and nascent industry that has been devoid of research for about half a century. This study examined the effects of exogenous shock on price at each phase of the value chain—Farm (hemp biomass), and its impact on prices at other phases of the value chain—Intermediary Processor (crude cannabidiol hemp) and Final ...

Characterization of Elementary Industrial Hemp (Cannabis Sativa L.) Fiber and Its Fabric

Journal of Natural Fibers, 2023
In recent years, man-made fibers have been largely replaced by natural fibers as a reinforcement in polymer composites. Hemp fiber has the ability to be used as reinforcement in polymer composites due to its biodegradability, abundance, higher fiber ...

Accelerating Sustainable Epoxy Resin Development Through Bayesian Optimization and Inverse Design

Journal of Applied Polymer Science, EarlyView.
Development of a machine learning framework for the optimization of the Tg of partially bio‐based epoxy resin formulations in a 13‐component design space using Bayesian optimization, active learning, random design, and inverse design. The results show that the BO effectively navigates high‐dimensional formulation spaces, and the final ML model could ...

Planting Density and Fertilization Evidently Influence the Fiber Yield of Hemp (Cannabis sativa L.)

Agronomy, 2019
Hemp is one of the most important green (i.e., environmentally sustainable) fibers. Planting density, nitrogen (N), phosphorus (P) and potassium (K) significantly affect the yield of hemp fiber. By optimizing the above main four cultivation factors is an

Mechanical, thermal and ballistic performance of epoxy composites reinforced with Cannabis sativa hemp fabric

Journal of Materials Research and Technology, 2021
Among the natural fibers, the hemp fiber extracted from the stem of Cannabis sativa is, after sisal, the second most applied as reinforcement of polymer composites and increasingly used from automotive to civil construction industries. Polypropylene (PP)
