A pertinent question is why the sandwich construction has not been used more extensively. The reason is that traditional sandwich construction is prone to separation between the skin and core.

The basic sandwich technology is simple. A lightweight foam core in between two halves of a plate increases the stiffness and strength with an incredible factor.

stitched panels avoid delamination

In order to circumvent the delamination of skins and foam, Acrosoma offers a solution using a tri-dimensional reinforcement sandwich panel. Acrosoma does this on the basis of proven technologies which have been integrated in a unique and reliable way.


ACrosoma panel technology Acrosoma combines the advantages of a standard sandwich panel with stitched panels.

A hard-hat foam core is responsible for

High strength to weight ratio

isolation and shock resistance. Excellent isolation

Constant quality - due to continuous production

High buckling and impact resistance

Blast energy absorption

Delamination between core and skin made impossible. Perfect crack stopper: 4 stickes per cm2 Integrated fibre optics for structural health monitoring

The outside layers of the panel are sewn together straight

Three layers of glass fiber on each side of the panel are

through the foam with the aramide fiber. This prevents the

reinforced where necessary with carbon fiber and are

tearing of the outside layers and increases the impact

A foam core is pulled through the entire machine. First, this foam core is covered on top and bottom by a complex of fibres (mostly glass) and stitched. A wetter injects resin and the combination is heated up in a die. The cured panel is pulled through the whole process by a puller, each time the needles have left the core.


ACROSOMA PRODUCTION

The Acrosoma速 production machine is globally patented production equipment that has proven its reliability. It combines textile and composite technologies. Although Acrosoma速 technology is young; it relies on decades of experience.
