The Answer for Requirement Number 2a
Composite materials are materials made from two or more constituent materials with significantly different physical or chemical properties, that when combined, produce a material with characteristics different from the individual components. The individual components remain separate and distinct within the finished structure. In general, composite materials are used to gain specific combined properties that individually the materials do not possess.
Typically, a composite material comprises reinforcement (fibers or particles) and a matrix (binder). The reinforcement provides strength and rigidity, contributing significantly to the composite’s mechanical performance, while the matrix binds the reinforcement and protects it from damage by distributing forces between the reinforcement materials.
Some examples of composite materials include:
- Fiberglass: Made of fine fibers of glass and often used in storage tanks and corrugated roof sheeting.
- Carbon Fiber: Used for high-performance applications like aerospace due to its high strength-to-weight ratio.
- Concrete: A composite that has been used for centuries, composed of aggregate and cement binder.
- Wood: A natural composite of cellulose fibers in a lignin matrix.
- Engineered Wood: Includes a range of products such as plywood, MDF, and particle board.
The history of composite materials is quite extensive, with early examples dating back thousands of years:
- Ancient Times: The first composite materials were made by humans in the form of mud bricks (a combination of straw and mud) and early forms of concrete (made from mixing aggregate materials with a cementing substance).
- 1940s: With the advent of World War II, technology advanced rapidly, and new materials were needed for the war effort. One of the most significant developments was the creation of fiberglass, which was used in various applications, from aircraft to boats.
- 1960s: Carbon fiber composites were developed. Due to their high strength and lightweight properties, they were initially used in aerospace applications.
- 1970s – Present: The use of composites has expanded into numerous industries, including automotive, construction, sports equipment, and more, due to advancements in manufacturing processes and the development of new types of composites.
Today, composite materials are a crucial part of many different industries. They’re valued for their strength, lightweight, and versatility. Research and development continue to advance the possibilities of composite materials, exploring new combinations of materials to solve engineering challenges.

The Answer for Requirement Number 3a
Composite materials are made by combining two or more materials with different properties. The process usually involves a reinforcement material (such as fibers or particles) and a matrix (a binding material). The reinforcement provides strength and rigidity, while the matrix binds the reinforcement and distributes forces between the reinforcement materials.
One common method for making composites is the lay-up process, often used in fiberglass production. This involves laying down layers of reinforcement (like fiberglass cloth), then adding the matrix material (like a resin), which is often done with a brush. The composite is then left to cure. Other methods include extrusion, injection molding, and pultrusion, among others.
The following table discusses three different composite reinforcement materials, their characteristics, and their uses. For this information, refer to the SDS for each material for detailed health and safety information.
|Material||Positive Characteristics||Negative Characteristics||Uses|
|Fiberglass||Strong, lightweight, relatively inexpensive, non-conductive, resistant to corrosion||Can irritate skin and lungs, weaker than carbon fiber||Used in boat hulls, car bodies, sports equipment, and insulation|
|Carbon Fiber||Extremely strong, lightweight, rigid||Expensive, can shatter if subjected to a sharp blow||Used in high-performance applications such as aerospace and sports equipment|
|Kevlar||Extremely strong, lightweight, heat resistant||Expensive, can degrade with UV light exposure, difficult to cut||Used in bulletproof vests, fire protective clothing, ropes, and cables|
Safety Data Sheets (SDS) are essential for understanding the safety and environmental precautions necessary for these materials. They include information on toxicity, disposal, and safe handling, among other things. To find the SDS for these materials, you would typically go to the manufacturer’s website or use an online database of SDS documents.
Due to the length and complexity of SDS documents, they cannot be fully covered here. However, in general:
- Fiberglass, carbon fiber, and Kevlar can all irritate the skin and respiratory tract. Adequate protection (such as gloves and masks) should be used when handling these materials.
- Disposal of these materials should be done according to local regulations. They generally cannot be disposed of in regular trash due to their non-degradable nature and potential to cause harm if not handled properly.
- Safe handling procedures generally involve minimizing dust generation and accumulation, avoiding breathing dust or fumes, and washing hands thoroughly after handling.
For detailed information, consult the specific SDS for the material in question.
The Answer for Requirement Number 3b
Resins are typically used as the matrix in composite materials, binding together the reinforcement materials and providing overall shape to the composite. Here are three different types of resins used in composites:
- Polyester Resin (Thermoset): Polyester resin is a low-cost resin option often used in marine and automotive applications. It offers good mechanical, chemical resistance and electrical properties. However, it has a shorter shelf-life and is less impact-resistant than epoxy resins. Polyester resin also emits styrene during the curing process, which is harmful to inhale and contributes to air pollution.
- Epoxy Resin (Thermoset): Epoxy resin provides excellent mechanical properties and adhesion, superior chemical resistance, and low shrinkage, making it suitable for high-performance applications like aerospace. However, epoxy resins can be more expensive than other resin types and can cause allergic reactions.
- Polyethylene (Thermoplastic): Polyethylene is a low-cost, lightweight, and highly versatile thermoplastic resin. It has excellent chemical resistance but is not as strong or heat-resistant as many thermoset resins.
The Safety Data Sheet (SDS) for each resin provides more detailed safety and handling information. Generally, these resins all need to be handled with care, using appropriate protective equipment to prevent skin and eye contact and inhalation of fumes. They should be used in a well-ventilated area.
Disposal of these resins should be done in accordance with local regulations. They should not be disposed of down drains or into water sources due to their potential environmental impact.
Please note that specific safety, handling, and disposal information will vary depending on the exact formulation of the resin. Always consult the SDS for the specific product you are using for the most accurate and detailed information.
|Material||Positive Characteristics||Negative Characteristics||Uses|
|Polyester Resin (Thermoset)||Low cost, good mechanical and chemical resistance||Shorter shelf-life, less impact-resistant, emits harmful styrene during curing||Marine and automotive applications|
|Epoxy Resin (Thermoset)||Excellent mechanical properties and adhesion, superior chemical resistance, low shrinkage||More expensive, can cause allergic reactions||High-performance applications such as aerospace|
|Polyethylene (Thermoplastic)||Low-cost, lightweight, highly versatile, excellent chemical resistance||Not as strong or heat-resistant as thermoset resins||Used in a wide range of everyday products from plastic bags to bulletproof vests|
The Answer for Requirement Number 3c
