ECI Composites Material Science: 2-2 Plaster of Paris Matrix Composite

Introduction to the reinforcement affects composite behavior and the three point bend test. Students will be creating plaster beams with and without reinforcement. The reinforcing materials can vary, however they must be verified by the professor. Plaster beams are created using plastic molds with reinforcements laid within. The beams are then tested using a home made mechanical testing apparatus, or even possibly using an Instron machine depending on the equipment available. Flexural strength is also calculated for each beam.
