Issues in Machining Epoxy Resin - nano Reinforcement Composite Systems with Respect to Surface Integrity and Tool Wear

Original language description

Polymer systems are widely used due to their unique properties, such as ease of manufacture, light weight, high structural strength and more. They are used in a wide range of applications – from the aerospace and automotive industries to objects of everyday use. However, polymers have a lower modulus of elasticity and strength compared to metal and ceramic materials. One way to improve their mechanical properties is to reinforce polymers with inclusions (fibers, platelets or particles). Currently, developments are underway in the use of nano-reinforcements and the production of nanocomposites. Experimental investigations point to the occurrence of new phenomena capable of noticeably influencing the properties of the resulting composite - an increase in strength when using relatively small amounts of reinforcement. Also, reducing the size of these components to the nanometer level causes an improvement in the mechanical and physical properties of the composite due to the presence of a large number of nanoparticles (large specific surface area of the reinforcement). One of the most desirable nanoparticles is SiO2, which is inexpensive, non-toxic, biocompatible, highly thermally and mechanically stable, and particularly effective as a mechanical reinforcement. All these aspects make it an ideal choice for filler in composites. The size of spherical SiO2 nanoparticles alone is around 20 nm. The disadvantage of this filler is the high hydrophilicity of the SiO2 surface, which causes the aggregation of nanoparticles that are then difficult to disperse in the polymer matrix. The machining of composite systems is now well described. Nevertheless, new studies are still appearing that address the issues of tool wear, optimization of machining conditions, delamination and the character of the workpiece surface. A noticeable drawback of the application of nano-strengthening is the still insufficient understanding of the synergy of the individual phases.
