Flight Design selects Hexcel’s HexPly® M79 carbon fiber prepregs for ultralight aircraft

German ultralightaircraft specialistFlight Design has chosen Hexcel as its key supplieradopting low-­temperature curing prepreg intoits aircraft production.Hexcel’s HexPly® M79Carbon Fiberprepregs delivera more consistent final product by ensuring constant material quality and processing parameters and produce a lighter and stronger aircraft at a more competitive overall cost.

Flight  Design  has  always  relied  heavily  on  composites  for  its aircrafts’  ultralight  construction and  turned  to  long-­term  composite  materials partner Lange  +  Ritter,  part  of  Hexcel’s  European  distribution  network,  when  they  began  searching  for  a  prepreg  material  solution. Hexcel  and  Lange  +  Ritter  created  several  new  product  codes  specifically  for  Flight  Designand  then  supplied  materials  for  initial  handling  trials  and  prototyping.  Hexcel’s  HexPly  M79  low  temperature  curing  out  of  autoclave  solution was first  used  in  the  new  F2  prototype.As  part  of  its material  supply  package,  Lange  +  Ritter  also  sent  a  team  for  on-­site  training  and  technical  support,  allowing  the  Flight  Design  production  team  to  get  up  to  speed  with  prepreg  as  quickly  as  possible.

HexPly  M79  prepregs  can  be  cured  at  temperatures  as  low  as  70 ?C  for  eight  hours  or  80 ?C  for  four  hours,  reducing  tooling  costs  and  increasing  buildrates. When  combined  with  Hexcel’s  innovative  air  venting  Grid  Technology, HexPly  M79  UD  carbon  tapes  can  also  be  laminated  with  reduced  debulking  steps  to  produce  void  contents  <1%  irrespective  oflaminate  thickness.  With  consistently  low  void  contents  and  improved  mechanical  properties,  designers  and  engineers  are  able  to  further  optimize  highly  loaded  composite aerostructures.

As  more  and  more  of  its  composite  aircraft  parts  are  transferred  to  prepreg  technology,  Flight  Design  is  seeing  the  benefits  of  its  switch  to  HexPly  M79.  Lay-­up  is  cleaner  and  more  precise,  low temperature  oven  curing  is  quick  and  energy  efficient,  and  the  manufacturing  process  consistently  outputs  exceptionally  high-­quality  laminates  and  components.

The  long-­term  strategy  is  to  integrate  HexPly  M79  across  the  range,  with  Hexcel  materials  lightening  the  ultralight aircraft at  Flight  Design  even  further.

“The  materials  and  technology  package  from  Hexcel  and  Lange  +  Ritter  has  been  a  big  success  for  us  at  Flight  Design,”  comments Daniel  Gunther,  Managing  Director  at  Flight  Design.  “When  we  took  the  decision  to  switch  to  prepreg,  we  looked  at  many  options  but  only  Hexcel  and  Lange  +  Ritter  could  offer  us  low  temperature  out-­of-­autoclave  (OOA)  curing,  globally  respected  material  quality  and  the  customer  service  levels  we  were searching  for.”
