Figure 3.1, located below, shows a picture of the 3-point-bend test apparatus. Figure 3.1 shows the specimen supports, force applicator, and displacement measurer via call-outs. These components serve the following purposes: Specimen supports – support the specimen during the test Force applicator – applies the force to the specimen and communicates the force being applied to the software Displacement measurer – measures the displacement of the specimen and communicates the displacement of the specimen to the software Figure 3.1, located below, shows a picture of the tensile test apparatus. Figure 3.1 shows the specimen supports, force applicator, and extensometer via call-outs. These components serve the following purposes: Specimen supports – support the specimen during the test Force applicator – applies the force to the specimen and communicates the force being applied to the software Extensometer – measures the elongation of the specimen and communicates the elongation to the software Procedures The procedure for the lab is detailed in the numbered list below. The composite specimens were fabricated for the tensile and bend-test A composite used for tension testing was fabricated by cutting out six same-sized pieces of bi-directional E-glass: two at ± 〖90〗^o and four at ± 〖45〗^o. The pieces were adhered to one another using a wet lay-up with the six pieces of bi-directional E-glass at the following angles in
