AI Technical Summary

Benefits of technology

The resulting hemp-based composites exhibit enhanced stiffness, thermal, and electrical properties, exceeding expected properties, and demonstrate the potential for widespread sustainable composite production, addressing the challenges of hemp hurd utilization and environmental sustainability.

Problems solved by technology

Unfortunately, the use of the hurd has been shunned to date, even though it is the primary biomass of the plant.
These features make hemp an intriguing option for cultivation, but the many difficulties with the plant have precluded its use on any scale up to this point.

Embodiment Construction

[0073]Inclusion of hemp-derived nanofillers into a biodegradable polymer matrix represents an understudied sustainable / biodegradable nanocomposite. There is limited research on hemp-derived biodegradable nanocomposites due to the lack of a hemp industry in the United States. The Marijuana Tax Act of 1937 placed taxes, penalties, and enforcement provisions on the sale of cannabis, hemp, or marijuana. This act placed industrial hemp on the controlled substance list and made it illegal to grow. However, on the federal level, the 2014 Farm Bill that was passed now allows universities and state departments of agriculture to grow industrial hemp for research purposes. In addition, the Industrial Hemp Farming Act of 2018 was introduced to remove industrial hemp from the controlled substance list as long as it contains less than 0.3% Tetrahydrocannabinol (THC). However, some state laws still do not allow the cultivation of industrial hemp (National Conference of State Legislation).

Abstract

A composite material comprising a polymer and a carbonized hemp filler, wherein the carbonized hemp filler is produced by carbonizing hemp at a temperature of at least 1100° C. to produce a char; and milling the char to produce a particle size, wherein the filler comprises 95% of particles of less than 10 microns in size; and wherein the hemp filler comprises between 1 and 50% of the total mass of the composite.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a divisional of U.S. patent application Ser. No. 16 / 395,397 filed on Apr. 26, 2019, which claims the benefit of U.S. Provisional Patent Application No. 62 / 663,674 filed on Apr. 27, 2018, the contents of which are incorporated herein by reference in their entirety.FIELD OF INVENTION[0002]The present application is generally related to composite materials comprising a cellulosic material and a polymer, wherein the cellulosic material is preferably generated from hemp plants.BACKGROUND OF THE INVENTION[0003]Sustainably reinforced polymers are of interest in numerous industries ranging from industrial, automobile, medical, and other applications. These reinforced materials often have superior strength-to-weight and stiffness-to-weight ratios and have a wide range of physical, thermal, and electrical characteristics that make them ideal for product creation.[0004]Composite thermoplastics can offer increased strength, decrea...
