Sandwich Panels consist of a skin and a core, each serving distinct functions. TAFNEX™ Sandwich Panels, typically featuring a skin and core made of the same polymer (PP), are easily recyclable. They are often used as flat panels but can also be processed through Thermoforming, Compression Molding or Injection Molding. Discover more below.
Any TAFNEX™ Sheet can serve as the skin material. The typical choice is the use of a thin cross-ply TAFNEX™ Structural Sheet or a TAFNEX™ Woven Sheet.
Core materials offer versatile options for various applications. Typically, low-density foams or honeycomb cores are selected, but there are also unique core materials to explore. Additional information about the possible core materials is available below.
Thicknesses typically range from 10 to 20 mm, though we are fully capable of producing panels with alternative thicknesses to meet your individual demands.
TAFNEX™ Sandwich Panels are made to your required dimensions, not restricted by standard sizes. Panels can be produced up to 3 meters in both length and width.
Following nature's lead, honeycomb cores have a storied history in aerospace and maritime applications, distinguished by their impressive strength-to-weight ratio. Although traditional aluminum and paper-based cores continue to be utilized, there is a growing trend towards the adoption of polymer-based cores.
Traditionally, honeycombs are constructed using hexagonal shapes. In contrast, tubular honeycombs are fabricated from circular cylinders, enabling them to withstand forces from multiple directions while preserving their form. The isotropic mechanical properties of these individual cells contribute significantly to the overall stability of the honeycomb plate, and consequently, the final product.
Although the compression strength of foam cores may be marginally lower than that of honeycomb cores, they provide superior thermal and acoustic insulation. Furthermore, they are less likely to cause surface marks.
Apart from the standard honeycomb and foam cores, there are other specialized core materials available on the market. A notable example is the textile-reinforced polypropylene foam core material by Lighterials, tailored for microsandwich uses.
Also, a very high-performance sandwich structure can be realized by using a PP-GF LFT core.
TAFNEX™ Sandwich Panels, typically deployed as flat sheets, can also be converted into three-dimensional components. The process of bonding the skin and core may also be performed at this processing stage, particularly when employing foam cores.
The direct combination of a TAFNEX™ skin and foam core in the Thermoforming process enables the production of drone blades in high volumes. Thanks to its thermoplastic characteristics, the propeller not only enhances safety but also allows for efficient recyclability.
TAFNEX™ is making significant steps in the rapidly expanding sport of Pickleball. Through the utilization of TAFNEX™ Sandwich Panels, the rackets provide not only a novel playing experience but also the advantage of being recyclable.
Utilizing TAFNEX™ Sandwich Panels for underbody shielding can deliver both physical protection and thermal insulation, contributing to improved efficiency in electric vehicles.
