Standard 1
Discuss what composites are. For example:

1. Define: composite, reinforcement, matrix, fiber, resin, plastic.
   
2. Concept of composites: A reinforcement embedded in a matrix (compare to islands in an ocean).
   
3. Role of the reinforcement: Carry the load, give strength, give stiffness.
   
4. Role of the matrix: Hold reinforcements in place, protect from environment, contribute to impact toughness.
   

Standard 2
Discuss the history of composites and how they have developed over the years. For example:

1. The use of straw combined with mud to make bricks - 3000 B.C. (Reinforced concrete is a more modern example).
   
2. Mongolian bows were made from a bamboo core with horn on the side under compression (facing the bowman) and sinews on the tensile side (away from the bowman) and held together with animal glue and, perhaps, wrapped with silk threads over a birch bark cover.
   
3. Early aircraft were designed with wooden frames covered with cotton cloth and waxed string.
   
4. Later aircraft used rayon (reconstituted cellulose) to reduce weight.
   
5. Plywood (multi-layers in which the grains are crossed, held together by adhesive) was sometimes used as a substitute for aluminum.
   
6. Modern aircraft make regular use of fiber glass, non-fiber glass, and contemporary composites.
   
7. High performance aircraft use layers of carbon fibers and epoxy resin laid with fibers pointing in different directions in each layer which are then cured to bind all together in a solid structure.
   

Standard 3
Discuss the use of composites in today's society. For example:

1. Fiberglass reinforced plastics (FRP) use for mid-strength/low cost and high strength/low weight in such areas as:
   
   • Automobiles, boats, windmill blades, tubs and showers, medical devices, architectural structures, storage tanks
   • Spacecraft, airplanes, helicopters, body armor, artificial feet, energy applications, advanced automobiles and non-structural applications (heat transfer, electrical conductivity)
2. The FRP industry (resin manufacturers, fiberglass manufacturers, fabrication machine makers, and fabrication shops).
   
3. Discuss the advanced materials industry (prime aerospace companies, major parts suppliers, minor parts suppliers, tooling suppliers, manufacturing machine makers, production materials vendors, fiber manufacturers, resin manufacturers, prepreg companies, core material makers, fiber weavers, and preform makers).
   

Standard 4
Discuss the advantages and disadvantages of composites over other materials. For example:

1. Strength, stiffness, and weight (compare composite to steel and aluminum).
   
2. Fatigue and crashworthiness (sudden versus progressive failure modes).
   

Standard 1
Compare fiberglass reinforced plastics (FRP) and advanced composites. For example:

1. In FRP the properties of the plastic dominate, and the reinforcement adds strength and stiffness, whereas advanced composites are dominated by reinforcement properties and the matrix is secondary.
   
2. FRP sometimes uses random fiber orientation, whereas advanced composites fibers are carefully placed.
   
3. The material properties of the individual components in advanced composites are typically higher.
   
4. Fiberglass or natural fibers are used in FRP whereas carbon or other very strong and stiff fibers are typically used in advanced composites.
   

Standard 2
Define the differences between thermoset and thermoplastic resins. For example:

1. Thermoset resins
   
   • Often a liquid polymer at room temperature, or a polymer dissolved in a reactive solvent (the solvent combines with the polymer during the curing process to create the solid)
   • Polymerization (curing) is achieved by using an initiator to start the reaction, perhaps with some heat applied, while the resin and reinforcement are in a mold
   • May be softened, but can never be re-melted or returned to their uncured (liquid) state
   • Parts can be made in high production quantities, but cure times must allow for the chemical reaction (polymerization or crosslinking) to occur
2. Thermoplastic resins
   
   • May be formed to a desired shape by applying pressure (usually in a mold) when the resin is softened or melted
   • May be reshaped by re-softening or re-melting and by applying additional pressure.
   • Have a high melting temperature
   • Excellent for mass producing small parts (short cycle times)
   • May easily be recycled

Standard 3
Identify the reinforcement material forms that are available for use in composites. For example:

1. Roving
   
2. Chopped strand
   
3. Non-oriented strand mat

5. Preforms (braids, knits, stitched)

2. Select the resin that meet the specifications.
   
3. Select the reinforcement materials that meet the specifications.
   
4. Control the reinforcement to resin ratio (fiber volume).
   
5. Resin system components are mixed by weight, not volume.
   
6. Understand the cure profile (heat cycle).
   
7. Consolidate the composite during cure to ensure that the layers are properly adhering, fiber resin content is correct, and the voids are reduced.
