Conference Paper
Full-text available
Fused deposition modeling (FMD) is considered one of the most common additive manufacturing methods for creating prototypes and small functional parts. Many researchers have studied Polylactic acid (PLA), Polycarbonate (PC), and Acrylonitrile butadiene styrene (ABS) as a material for fused deposition modeling printing. Among them, Polylactic Acid (...

The additive manufacturing process of chicken feather fiber (CFF) filled polybutylene succinate (PBS) biopolymer, a sustainable 3D printing process using fully biodegradable and biocompatible polymers that are reinforced by animal-based short fibers reclaimed from agricultural wastes, is studied in this research. The protein-based natural fibers fr...

This Work-in-progress paper presents the pilot study of implementing a Virtual Reality (VR) environment to teach a junior-level Mechanical Engineering laboratory class at Prairie View A&M University. The target class is the manufacturing processes laboratory, which initially aimed to provide a hands-on experience with various manufacturing equipmen...
Conference Paper
Full-text available
A novel additive manufacturing process utilizing the laminated object manufacturing (LOM) technology with woven natural fiber-reinforced biopolymer is investigated in this paper. Traditional synthetic composite materials are products from nonrenewable crude oil with limited end-of-life options, and therefore not environmentally friendly. The contin...
Conference Paper
The demand for bolting components is expected to grow as fasteners remain a standard method of assembling parts. UNS N07718 is a Nickel-based chromium superalloy, which is the most popular grade of choice for its high yield strength. Forged UNS N07718 bolts of larger diameter have been growing in demand. In this paper, a non-conforming forging proc...
Chapter
Full-text available
One of the novel ways of producing low-cost and environmentally-friendly bioresins is through the growth of fungal mycelium. In this chapter, the most popular fungal species and cultivation substrates are introduced, followed by factors that affect the synthesis of biopolymers, which include nutritional factors, modes of cultivation, environmental...
Article
Full-text available
This paper presents a finite element based explicit fluid-structure coupling method. The derived method is proposed to solve flow-induced multi-particle motion in the low Reynolds number flow. The particle motion is treated as a non-linear geometric dynamic problem. The Total-Lagrangian finite element method is applied to describe and discretize th...
Conference Paper
Full-text available
This paper investigates the mechanical properties of potential sheet stocks of a Laminated Object Manufacturing (LOM) 3D printer made using woven jute fabrics infused with two types of bioresin. The combinations of bioresins and the reinforcements would make green sheet stocks that are expected to be environmentally friendly comparing to traditiona...
Article

A new approach to manufacture biocomposite sandwich structure is introduced with all materials naturally derived, including jute, flax and cellulose textile as reinforcement skin; mycelium-bound agricultural waste as lightweight cores; and a soy-based bioresin as a matrix. This new material could be used to replace many of the plastic products that...

Article
Full-text available
Roller infusion by nip rollers is widely used in the infusion industry with broad applications, which is also adopted as one of the 7 steps of a newly developed manufacturing process for making fungal mycelium based biocomposites. One important technical issue related to infusion textile reinforcements for such biocomposites is how to predict and c...

A non‐traditional approach to manufacturing biocomposite sandwich structures is introduced where all materials are naturally derived including natural fiber textile (jute, hemp and cellulose) as skin; mycelium‐bound agricultural waste as core; and a bioresin as matrix. This paper focuses 2 on issues related to three specific steps of the seven‐step...

The manufacture and use of natural, textile-reinforced and shaped skins to replace rigid tooling for fungal mycelium-based, biocomposite sandwich structures are investigated. The motivation is a new manufacturing process proposed for such biocomposites that includes: cutting individual natural textile plies; impregnating multi-ply layups with natur...

A manufacturing cost model is created that includes all labor, material and overhead costs for novel mycelium-based biocomposite sandwich structures produced by a commercial firm. This model is implemented through a spreadsheet to calculate the equivalent uniform annual costs (UAC) of all manufacturing facilities. A simulation model of the manufact...
Conference Paper

A new approach to manufacturing biocomposite sandwich structures is introduced. Materials used in the biocomposite are natural textile reinforcement, mycelium-bound agricultural waste as core, and bioresin. This paper focuses on three specific steps of the manufacturing process: filling pre-stamped textile shells with core mixture; allowing the cor...

Mechanical stabilities and properties are critical in real applications of materials, as well as material and machine design [1-3]. With the success of graphene, graphene-like materials arose tremendous interest in the past few years. Different from bulk materials, two-dimentional (2D) materials have prominent non-linear elastic behaviors. Here we...

The use of polymer matrix composite (PMC) materials, such as E-Glass fibers in an epoxy matrix, has grown and continues to grow steadily in a variety of markets, because their structure and processing can be tailored to applications requiring high strength, high stiffness, low weight, and/or low thermal conductivity. Unfortunately, traditional PMC...
