Potential for Nanoparticle Agglomeration

Potential for nanoparticle agglomeration presents a significant challenge in the use of nanomaterials in RTM resins. When nanoparticles are not properly dispersed, they tend to cluster together, forming larger agglomerates that compromise material properties. This results in uneven distribution within the resin matrix, adversely affecting the composite’s mechanical and thermal performance.

Agglomeration occurs due to strong Van der Waals forces and surface energy inherent to nanoparticles. These attractive forces promote particle sticking, especially when dispersion techniques are insufficient. Consequently, nanoparticle clustering can create weak spots in the cured resin, reducing overall structural integrity.

Overcoming this obstacle requires effective dispersion strategies, such as surface modification or advanced mixing techniques. Proper dispersion ensures that nanomaterials impart their full advantages without forming detrimental agglomerates, thus maintaining the desired enhancements in RTM resins for carbon fiber parts.
