Fig. 18. Relationship between mechanical properties and injection temperature (Shibata et al., 2010). The increasing of the thickness of the GFRTP laminate outer shell significantly improved the bonding strength between the shell and the injection-molded ribs (Tanaka et al., 2015). To the thicker laminate's higher heat capacity this was attributed, allowing it to penetrate deeper into the rib structures during molding and create a stronger bond; see Fig. 20. The adding of CB did improve conductivity, the carbon fibers became misoriented, losing their typical alignment with the flow direction (Drubetski et al., 2005). This misorientation was attributed to the uneven distribution of CB particles, which created viscosity gradients within the material and altered the flow behavior during molding.
