Testing and unique systems for foam and composite materials
TSSD; the composite innnovation
Joining components to lightweight honeycomb material has traditionally been achieved through a variety of fixing elements and techniques such as rivets, adhesives, potted or floating inserts and, of course, nuts and bolts.
The TSSD direct Installation fastening system creates an incredibly strong joint in a vast range of these materials, eliminating the need for pre-hole. The TSSD component is made from a fibreglass reinforced thermoplastic polymer. This strength makes it possible to apply a specific axial loading to revolution ratio, resulting in a fast high-strength joint without the need to create a pre-hole.
Our demo rig allows sufficient optimisation to achieve accurate testing, making it possible to record the setting parameters used. Such has been the impact, that designers at many of Germany’s main vehicle manufacturers now ‘design in’ new TSSD variants. Pull-out loads for TSSD into the broad standard honeycomb material are typically around 800 N, with loads of up to 1000 N achievable. In organo type materials, this rises to as much as 1800 N.
RSD; high strength joining for expanded polypropylene
The EJOT EPPsys was developed to provide a fast and reliable option to join components to modern lightweight foamed materials, in particular EPP (expanded polypropylene).
Our EPPsys rig demonstrates the EJOT RSD friction welding boss and its effectiveness into EPP foams and PP honeycomb materials. RSD is embedded in the EPP foam and securely connects to the molten material.
EJOT’s EPP joining systems lend themselves to manual through to fully automated installation scenarios and have proven themselves in a wide variety of application solutions around the world.
