This report details the process for the design of a composite laminate tube, the software package 'MathCAD' was used to determine a lamina design with a configuration that avoids mechanical failure under loading conditions. It was also used to obtain twist angles and maximum stresses for specific lamina wind up angles. The report will provide analysis of the methods used to obtain these criteria.
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
I learn engineering concepts in courses such as ‘Advanced CAD’ where we learn modelling and designing using industrial CAD software – Catia, AutoCAD and SolidWorks - to courses about the mathematics and theory of thermodynamics, heat transfer, properties of materials and the design of machine elements - forces, torsion, lubricants and failure theory – accompanied with lab experience. I am dedicated and would like to learn the multiple skills that this position has to offer. I believe that my determination to learn and knowledge of manufacturing and engineering makes me a strong candidate for working at Viryl Technologies Corporation for the Product Design/Advanced Manufacturing Assistant co-op position. I look forward to hearing from you in the next few weeks so that we can arrange for an interview. To arrange an interview, please contact the Engineering Co-op and Career Services office at engcoop@mcmaster.ca, or 905-525-9140 ext.
As a mechanical engineering student at the University of Windsor, I have cultivated a unique set of skills that would be tremendously useful in the field. During my time at the university, I have designed and engineered machine parts using specialised software such as AutoCAD and Catia. In addition, working with a group

Polymer Matrix Composites: Most commonly used matrix materials are polymeric. In general the mechanical properties of polymers are inadequate for many structural purposes. In particular their strength and stiffness are low compared to metals and ceramics. These difficulties are overcome by reinforcing other materials with polymers. Secondly the processing of polymer matrix composites need not involve high pressure and doesn’t require high temperature. Also equipments required for manufacturing polymer matrix composites are simpler. For this reason polymer matrix composites developed rapidly and soon became popular for structural
A composite material is a material that is made of (composed of) 2 or more constituent materials with different physical and chemical properties of each other. When combined, these materials form a composite with different properties from both of its constituent. Composite material is preferred for many reasons. It is often stronger, lighter, and less expensive when compared to traditional materials. Engineered composite materials, for example, are: mortars, concrete, metal composites, reinforced plastics, and ceramic composites. Nowadays, composites are widely used in many fields, especially in industries. Industries including oil and gas industry now use composites as their equipment’s material. One of the strongest reason why composites are now widely used, is that, use of composites lower the production cost for
Composite materials are the engineering materials made from two or more constituent materials they remain separate and distinct on a macroscopic level but forming a single component or Composites can defined as materials that consist of two more chemically and physically different phases separated by a distinct interface(matrix phase and dispersed phase). The different systems are combined judiciously to achieve a component with more and more useful structural or functional properties non-attainable by any of the constituent alone. In the composites usually Matrix phase is the primary or base phase having a continuous character or continuous molecular chain. But these Matrixes are usually less hard and more ductile phase. In composites it holds the dispersed (reinforcing) phase, shares a load with it. The Dispersed phase is encapsulated in the matrix in a discontinuous form called a secondary phase. This Secondary phase is usually stronger than that of the matrix phase, so is also called as reinforcing phase.
A "composite" is when two or more different materials are combined together to create a material which is superior and unique and holding different properties than earlier. Light weight high strength materials are essential in fabrication of aerospace structures like airframes, rocket motor casings, nozzles and wings. The composites are the materials formed by embedding fibers in the plastic that add characteristics like high resistance to fatigue, anticorrosive, high tensile strength or stiffness with weight savings up to 25-45% compare with conventional metallic designs. Composites possess greater reliability, which are capable to meet the design requirements, easier to achieve smooth aerodynamic profiles against drag reduction and high resistance to impact damage.
Composites, the wonder materials are becoming an essential part of today’s materials due to their advantages such as low weight, corrosion resistance,
The purpose of this lab is was to expose students to the manufacturing, fabrication, and testing of composites. In addition, it provides students with experience analyzing tensile and bending failures of composites. Three tensile specimens and two bend test specimens were tested during this lab. The tensile specimens were a wet lay-up of bi-directional E-glass, and the bend specimens were made up of a nomex honeycomb core with pre-preg uni-carbon faces. The three tensile specimens were tested, their elastic modulus and ultimate tensile strength calculated, and these value were compared to published approximately equivalent material properties. The two bend test specimens were tested, their face bending stresses were calculated, the shear stress in the core was calculated, and the bending and shear stresses were compared to published approximately equivalent material properties. A failure mode analysis was conducted for both the tensile and bend test specimens. This report summarizes the theory, procedure, and machines associated with the lab. Furthermore, it graphically and verbally displays the results draw from lab, and provides conclusions to improve the lab in the future.
The purpose of this study is to explore how some of the different composite materials are produced and how they are used as aircraft parts. The study seeks to answer the research question, why is the use of composite materials so attractive to aircraft designers and are the benefits of using composites worth trying to integrate them into existing aircraft designs? The goal is to analyze the many different uses of composites as aircraft parts and determine whether or not their use is beneficial.
However, modeling of ceramic matrix composites could be much more complex due to the unique feature of this type of material: 1) the fracture and brittle behavior of materials; and b) the nonuniform distribution of porosity in the ceramic matrix. CMCs are comprised of individual layers with unique material properties dependent on fiber orientation within the polymer matrix which is typically in a woven pattern. Therefore, CMCs often exhibit anisotropic or orthotropic properties, and have lower strains and higher degrees of fragmentations than metallic materials during machining. The unique features of CMCs make simulations more challenging due to the complex nature of the problem considering material nonlinear fracture, anisotropic or orthotropic property and multi-phase interaction apart from dynamic loading and plastic deformation in machining of metals.
