SPRINT®

SPRINT

With the advent of large blades, new prepreg technology was required to meet the increasing technical challenges in producing high quality components. Gurit’s award winning, patented SPRINT® technology, was ideally suited to fill this need and continues to lead the market as a composites technology platform for very large structures. 

Available in multiaxial or woven formats, SPRINT® enables the production of thick section laminates of very high quality (very low void content) using standard curing and vacuum bag operations. The product can also be used interchangeably and is compatible with other SPRINT® and prepreg products to produce very high quality components.

Some of the key benefits of SPRINT® are:

  • Autoclave quality but from vacuum bag processing
  • Excellent materials handling
  • Good health and safety
  • Fast lay-up
  • No debulking required
  • Reliability and repeatability
  • Excellent laminate quality
  • Reduced Costs



SPRINT® is available in two main formats:
       
STANDARD SPRINT®
The SPRINT® resin is sandwiched by a woven or multiaxial fabric on either side.  This product can be supplied on large rolls or smaller tapes for spar winding applications.  Another advantage is that this product can be supplied without a backer and reduce waste handling & disposal costs.
              

SINGLE SIDED SPRINT®
Typically used for heavier multiaxials, the SPRINT® resin is applied to one side of the reinforcement and to help with the lay-up process, a tack film can be applied to the other side.  This product is particularly effective when used as the first layer applied to a gel or process coat in order to eliminate any surface defects that can occur whilst processing and reduce the overall finishing time.

Another common application for SPRINT® is as an additional air evacuation system within an existing prepreg stack.  It is common to produce thick UD laminates for spar cap applications using heavy, sticky prepregs that cause excessive air entrapment between each ply.  By interleaving every 2nd, 3rd or even 4th ply with a biaxial SPRINT®, the resulting void content can be significantly reduced.

The novel SPRINT® concept opens up a new range of possibilities for optimizing not only the laminate but also the production process.  More often than not any area of the prepreg lay-up that suffers from poor consolidation or a high level or air entrapment can be remedied using SPRINT®.  It is even possible to use a SPRINT® as the final layer of the lay-up to act as the breather to consolidate the laminate.  This not only allows for a breather to be re-used, reducing the cost of consumables per blade, but with minimal resin bleed the resin content could also be reduced to save weight and money.
