LSCTP/CFR

The INTRO technology developed by TANGENT in 1990/91, has since become a recognised standard, and has been further developed and now guarantees optimum load baring characteristics combined with reliability in manufacturing and acceptable costs.

LSCTP - LOAD SPECIFIC COVERING THICKNES PROCEDURE

This is the procedure developed by TANGENT for optimising the relationship between load baring and weight with the maximum reliability. Weight is reduced through our new spheroidal grinding technique with orthogonal progression. Static load carrying ability is increased through the incorporation of carbon fibre reinforcements in the calculated and spheroidally reduced area.

How does LSCTP work?
Towards the finished aerodynamically efficient wingtips and leading edge - orthogonal to the longitudinal direction of the wing - covering strength can be progressively adjusted to the load requirement using a special, fully automated grinding technique. In areas in which there are little or no flight loads, more material has been removed. These areas can comprise up to 40%, representing an enormous overall weight saving.

CFR - CARBON FIBRE REINFORCEMENTS
These are carbon fibers which are incorporated into components to increase static load carrying ability. Manufacturing processes that use carbon fibers have been around for some time in our market and are offered by a number of manufacturers. The most frequently employed technique is to use carbon fibers in epoxy resin laminates. The use of epoxy technology in wing construction is still the best technology available and generally, if expertly manufactured, they can withstand the highest loads. The disadvantage of conventional use of carbon fibers in pure epoxy technology is the low production yield due to the long drying and reaction times. The resulting low output inevitably results in relatively high production costs.

What is different about TANGENT CFR?
Our special TA bonding technique, which has been successfully used for years, reduces cycle times significantly, resulting in greater output and high quality. Thanks to our newly developed technique, we have succeeded in incorporating carbon fibers in an adhesive mixing technology - hybrid adhesive technology. The advantage of this compared with conventional manufacturing technology is obvious: faster processing times mean high reproducibility. This combination permits technical optimisation of the product at an attractive price and in adequate volume.

It is all down to the right combination!
