Hands on activities

Math and Science Integration

High-performance applications of carbon fiber composites

Boeing 787

Nose section of Boeing 787

F-22 Fighter

Multifunctional composites have good mechanical properties and at least one other property of interest (e.g. electrical, thermal…) in a given application.

Nanoscale Materials

How Small is Nano Small?

How many carbon nanotubes does it take to stretch across the width of a human hair?

A human hair is about 100 micrometers.

A carbon nanotube is about 5 nanometers

That’s 20,000 carbon nanotubes per human hair.

Fiber

- Modulus (Stiffness)
- 5 x steel
- 400 x epoxy

- Electrical conductivity
- 1000 x copper wire
- 10^15 x epoxy (Quadrillion times)

Electrical Conductivity Specimens

Pure epoxy

0.015 wt. % CNT

- Introduce engineering concepts -stress, strain, elasticity etc.
- Three-point bending test to measure stiffness (modulus) of material.
- Shear Force, Bending moment.
- Differential Equations.

L = support span

P = Load

δ = displacement

w = specimen width

t = specimen thickness

Acceleration & velocity

Other applications (Work, Momentum, Energy)

Make quantitative observations and measurements with precision. (2B)

Organize, analyze, evaluate, make inferences, and predict trends from data. (2C)

Graph data to observe and identify relationships between variables(2D)

Develop and interpret a free-body diagram for force analysis (4E)

- Introduce Nanocomposites and carbon nano tube epoxy composites.
- Introducing Engineering concepts like bending of beam, Stress, Strain.
- Experiments.
- Field trips.
