2. Fiber misalignment

Figure 1: A 5 x 9 montage of size 700 mm x 900 mm detailing a misaligned region in a pultruded unidirectional carbon fiber reinforced composite.

3. Processing defects 3/4 porosity

Figure 2: A 4 x 4 montage of size 4.5 mm x 5.9 mm showing undesirable voids scattering throughout the matrix in a woven glass fiber-reinforced part.

4. Detection of microcracks

Figure 3: Microcarcks formed during a 3-point bending test of a liquid-molded test coupon (lower left). The microcracks propagated through the matrix and were stopped by the fiber bundles. Both the inter- and intra-bundle porosities are substantial.
