Structural Suitability and Modelling of Glass Fiber Reinforced Polymers

The elements of this design is curved, flowing, angular and thick. The curvature of the walls offer support to the roof, although that is not the

Polymer- Matrix Composited (PMC’s) : These are particulate composites fibered by dispersing the particles of varied geometry, layered composites build –up with parallel layers of two

In Figure 4, Young's modulus is plotted against yield strength. The diagonal line in the figure represents the material index M= σy/E. Materials below the diagonal line are the best candidate materials because they will remain elastic while providing the maximum conformability. All materials that cost more than $2.20 per pound and have a UV rating of "poor" were eliminated. Also, only materials that can be made through the polymer extrusion process were considered. The candidate materials are listed in Table 1 and ranked by the material index. The current material, TPV, is included in the table for

However, the absence of plastic deformation does not mean that composites are brittle materials like monolithic ceramics. The heterogeneous nature of composites result in complex failure mechanisms which impart toughness. Fiber-reinforced materials have been found to produce durable, reliable structural components in countless applications. The unique characteristic of composite materials, especially anisotropy, require the use of special design

Battenfeld HM 40/130 is the machine used in the laboratory session to mold Polypropylene. Thermoplastic materials such as nylon, polystyrene, polythene and polypropylene can be used in a process called injection molding.

In order to create a column-free space, designers and engineers opted to use free spanning composite glue-laminated (glulam) wood-steel arches supported by inclined concrete buttresses (Chodikoff, 2009). For the arches, the glulam slabs were made from engineered timbers consisting of wood laminations bonded together with strong, waterproof adhesives, resulting in a structural component as strong as steel. To increase the lateral stiffness, and assist in carrying the bending stresses from unbalanced snow loading, each arch has steel components anchoring the glulam slabs – resulting in a composite glulam wood-steel arch (Gregory, 2010). The use of glulam for the arches allowed for the roof’s large 100-metre span and curved element to be produced (Dietsch, 2011).

The use of fiber reinforced composites materials as an alternative to traditional metal materials is becoming widespread. The main technological advantages of these materials are low weight, high specific strength and stiffness, environmental resistance and long life. Compared to metals, composites can be easily made by relatively low tooling cost. Polymer matrix reinforced by woven fabrics is probably the most commonly used form of composites in structural application such as aircrafts, boats, and automobiles

In the novel, “Architecture” by Jonathan Glancey discusses the beginning of Architecture and how much Architecture has grown over the past years. In his book, he tries to inform and educate readers and other architects about the old and new styles that we are using today and how they were used during the 1880s. Glancey purpose was to apprise people about the different styles and techniques that are used around the world for architecture. Furthermore, he wants people to know how those different styles are being implemented to our buildings and our designs today. Glancey wants everyone to have more information about architecture, so they can formulate their own ideas and manufacture what they want to build. This book informs us about the different uses of materials that they use for architecture around the world such as plastic reinforced with glass to columns, floor plans, poche, brick, stone, wood, and much more.

There are numerous materials that are significant when it comes to constructing a building. Each one is vital in their purpose. This paper will address the materials that I feel are some of the most important aspects in building; foundation, wood, and concrete.

This course will allow me to explore an alternative construction material, which would potentially add to my knowledge and experience with engineering. Recently, I have been studying the structural and thermal performance of these structures,

L-D Tool & Die (LDTD) is a small manufacturer in Ontario who specializes in designing andmaking customized moulds as per customer’s requirements. LDTD was found by LaurieDickson in late 1980s. Since its inception, the company has continuously serving itscustomers by providing quality products and services. LDTD has developed a loyal customers throughout the years in business. The main services of LDTD are transforming synthetic resins and plastic material into a wide range of finished products, parts for other manufactured goods, and intermediate products consisting of shapes and forms made bya variety of fabricating methods. LDTD’s customers are mainly found in packaging construction, automotive industry, and plastic

In the 1930s, numerous synthetic composite technological breakthroughs were born. “In 1935, Owens Corning launched the fiber reinforce polymer (FRP) industry by introducing the first fiber glass. In 1936, unsaturated polyester resins were patented. Because of their curing properties, they would become the dominant choice for resins in manufacturing today. In 1938, other higher performance resin systems like epoxies also became available.” (Cite) The creation of FRP was vital to the military during World War II due to its notably high to strength to weight ratio. Not only was FRP used for electronic housings and other electronic components, but was also used to create the first fiberglass reinforced boat hull. The war efforts spawned copious amounts of commercial products made with FRP. This is how synthetic and natural composites were revolutionized during the 20th century.

be used to support a split-level floor. This application is commonly used in theaters and in private housing for aesthetic reasons. The stepped beam provides additional need for reinforcement detailing to fulfill the stress concentration at the stepped joint. The well-known advantages of fiber-reinforced polymer (FRP) composites over other strengthening materials make them a good choice for civil engineering applications.

Viewed from some glucose-related questions, the authors find that the construction industry in Malaysia is still underdeveloped in terms of the benefits and actual uses of glulam materials in both architectural and structural aspects. As an example is taken from the question where the author asks for the practical stage of this material to be used as the main structure of a wide-ranging building in malaysia, the majority of the respondents respond as likely to be practical. From the feedback it shows a low level of public confidence in this material.

Abstract: Advancement in recent years on the efficiency of glass fiber-reinforced polymer (GFRP) in production and cost benefits have increased their use as alternative means to steel rebar in bridge deck bases. The purpose in applying rebar is to increase the tensile strength of concrete. Considering the versatility of bridges there are many factors that need to be analyzed when choosing whether to use steel rebar or GFRP material such as: cost, tensile strength, and weather resistance. Stress-strain graphs were calculated, graphed, and analyzed to determine the yield tensile strength and stiffness of steel rebar and GFRP. Data collected from alkaline bath tests were graphed and analyzed to determine the thermal and corrosion resistance of each material. Costs per square inch of each material were also compared as well as each materials quality and life expectancy. The results of the conducted test analysis found the GFRP to have greater thermal resistance, lower cost, and higher life expectancy than the steel rebar, however the steel rebar’s stiffness was found to be about six times larger than the GFRP’s. These results suggest that the advancements in GFRP can provide longer lasting bridge structures and will change the future of construction and restoration of bridges.
