Manufactory ware linen, hemp, kenaf and jute fibers

UBC researcher sees future for flax and hemp as particleboard alternative. Hemp , or industrial hemp , is a strain of the Cannabis sativa plant species that is grown specifically for the industrial uses of its derived products. It is one of the fastest growing plants and was one of the first plants to be spun into usable fiber 10, years ago. It can be refined into a variety of commercial items, including. Although cannabis as a drug and industrial hemp both derive from the species Cannabis sativa and contain the psychoactive component tetrahydrocannabinol THC , they are distinct strains with unique phytochemical compositions and uses. Hemp has lower concentrations of THC and higher concentrations of cannabidiol CBD , which decreases or eliminates its psychoactive effects.

Natural fibre composite is an emerging material that has great potential to be used in engineering application. Oil palm, sugar palm, bagasse, date palm, coir, banana stem, hemp, jute, sisal, kenaf, roselle, rice husk, betul nut husk, and cocoa pod, etc. Natural fibre composites were reported to be used in many industries such as automotive, building, furniture, marine and aerospace industries.

Among the advantages of natural fibre composites include low cost, renewable, abundance, light weight, less abrasive, and they are suitable to be used in semi- or non-structural engineering components. Research on various aspects of natural fibre composites such as characterization, determination of properties and design has been exten- sively carried out.

However, publications that reported on research of manufacture of natural fibre composites are very limited especially in the form of book. Therefore, realizing the importance of manufacture of natural fibre composites, an edited book is proposed and it is hoped it can fill the gap of knowledge in the field of natural fibre composites.

Generally, manufacturing methods of components from natural fibre composites are similar to the manufacturing methods of components from con- ventional fibre composites such as glass, carbon and Kevlar fibres.

Modification of equipment used for conventional fibre composites may be required when manufac- turing components from natural fibre composites and the knowledge on these modi- fications is needed in natural fibre composite research community. Among the methods reported that are being used to produce components from natural fibre composites include hand lay-up, compression moulding, filament winding, injec- tion moulding, resin transfer moulding, pultrusion and vacuum bag moulding.

This book is also intended to address some research on secondary processing such as machining and laser welding of natural fibre composites. It is hoped publication of this book will provide the readers new knowledge and understanding on the manu- facture of natural fibre composites. We wish to express our gratitude to all the contributors who accepted our invitations to contribute and share their knowledge.

We admire their proficiency on scattered information from diverse fields in composite manufacturing and accepting editorial suggestions to finally produce this venture that we hope will be a success. We greatly appreciate their commitment.

Lastly, we thank Springer for their generous cooperation at every stage of the book production. Shah and Mike J. Saba, M. Paridah, M. Jawaid, K. Abdan, and N. Enamul Hoque, and M.

Sapuan, S. Sulaiman, E. Zainudin, and A. Misri, M. Ishak, S. Sapuan, and Z. About the Editors Salit et al. Sapuan and N. They have been used in many industries such as in automotive, aerospace, building and construction, and furniture industries.

At the end of this chapter, a section on design for sustain- ability DFS is included to address this issue. Design for manufacturing is the integration of product design and manufacturing process planning into one activity, and it meant to bridge the gap between design and manufacturing.

It is also known as concurrent engineering Sapuan and Mansor Design for manufacturing activity is in fact a design activity. It requires the con- sideration of all manufacturing and other related issues such as assembly, cost, sales, maintenance, disposal, and recycling early in the design process. It is not manufacturing activity itself but all considerations regarding manufacturing are made during this stage of product development.

It has become an accepted fact that decisions made during the early stage of design have a major effect on downstream activities. In practice, despite design for manufacturing philosophy is regarded as an inte- grated approach in design and manufacture, when coming to discussion on the issues or activities related to this philosophy, such as conceptual design, materials selection, and manufacturing process selection, each issue has to be treated in detail separately.

Some experts focus on materials selection, while others on conceptual design, but at the back of their mind, these activities should really be integrated. Ho et al. In this chapter only selected manufacturing processes are reviewed.

Pultrusion is a combination of two words: pull and extrusion. The process is similar to extrusion process, but in pultrusion, the product is developed by pulling the mate- rials rather than pushing the materials through the die as in the case of extrusion. Examples of thermosetting polymers that can be used in this process include epoxy and unsaturated polyester.

The composite is also cured in one of the dies. The end products are normally in the form of rods and bars. At the end of the pultrusion process, the products are cut to the required lengths. Fairuz et al. Kenaf composite rods were produced. In this study, three different parameters were investigated, i.

Figure 1. Filament winding is a composite manufacturing process to produce components that are normally circular in shape. It can be considered an open mould process and the mould is actually a rotating mandrel. The preimpregnated composites are in turn being wound around the rotating mandrel. The composites are also being traversed in x-direction so that even distribution of the composites along the length of the mandrel can be achieved.

Misri et al. Secondary processing like milling is required. Hand lay-up is an open moulding process to produce polymer composite product. This is a labour-intensive process where a high skill operator is required to perform the fabrication task.

The laying-up of a component begins with applying gel coat to the mould surface. A roller is used to consolidate the composites and the composites are made layer by layer. The process is repeated with more layers until the desired thickness is obtained.

Then the compos- ites are cured at room temperature or in an oven. Thermosetting resins like unsatu- rated polyester, vinyl ester, and epoxy are among the most commonly used resins. The fabrication work was carried out in association with an established boat builder. This process was labour intensive and required high skill operators to fabricate the boat. Then mould release agent was placed onto the mould surface to prevent the component sticking to the mould.

Methyl ethyl ketone peroxide MEKP was used as a hardener. RTM is an established composite manufacturing process that is normally used to fabricate automotive and aircraft components.

These reinforcements called performs are bound by means of thermo- plastic binder and then placed inside the mould cavity in the closed mould process. Resin is being transferred into the mould cavity by means of a variety of equipments such as by pressure or vacuum. Resins that are normally used in this process include polyester, epoxy, vinyl ester, and phenolic.

Salim et al. Stitching density was optimized to study its effects on the mechanical properties of the composites. The mechanical properties improved when the kanaf mat in composites was stitched compared to unstitched kenaf mat composites. Vacuum bagging is one of the processes in the category of prepreg moulding.

Another process is called autoclave moulding. The difference between these two processes is on the way curing process was done: one in vacuum bag oven and the other in an autoclave.

Nanoclay Reinforced Polymer Composites

Textile fibers occur as a multitude of different types. The forensic examination of fibers requires the scientist to have a thorough knowledge of and experience in the area of fiber technology and classification. The aim of this article is to present and discuss the most common types of fibers likely to be encountered in forensic examinations. A commonly accepted classification begins by dividing fibers into two groups: natural and manmade artifical fibers. The natural fibers may then be subdivided into three classes: animal protein , vegetable cellulose and mineral asbestos.

Linen is laborious to manufacture, but the fiber is very strong, absorbent, and dries faster than cotton. Garments made of linen are valued for their exceptional coolness and freshness in hot and humid weather. This word history has given rise to a number of other terms in English, most notably line , from the use of a linen flax thread to determine a straight line.
