Carbon Fibre

Car­bon fibers are com­po­sed almost ent­i­re­ly of ele­men­tal car­bon. The mole­cu­les are arran­ged in micro-crys­tals, ali­gned lon­gi­tu­di­nal­ly with the fiber’s axis. This align­ment makes the fibers more rigid than steel, des­pi­te being only a quar­ter to one-fifth the den­si­ty. Thus the­se fibers are espe­cial­ly appe­aling for light-weight con­struc­tion purposes.
In order to take advan­ta­ge of the­se pro­per­ties the fibers, each less than one-tenth the width of a human hair, must be con­tai­ned in some kind of frame – in this case a poly­mer matrix which func­tions to set the fibers in place.
A good car­bon com­po­nent con­tains more than 50% fiber.
daCar­bo uses the free­dom offe­red by car­bon fiber align­ment and com­po­si­te con­struc­tion in buil­ding its instru­ments not to cut down on weight, but pri­ma­ri­ly to opti­mi­ze the instrument’s vibra­ti­on. It beco­mes pos­si­ble to sup­press tho­se vibra­ti­ons in the tube that sim­ply was­te energy.
Instru­ment-makers, engi­neers, acoustic desi­gners and musi­ci­ans have worked tog­e­ther inten­si­ve­ly to mini­mi­ze the ener­gy loss in the air column, whe­re the sound is generated.
As a result, the instru­ments are remar­kab­ly easy to play in all regis­ters at supre­me sound qua­li­ty. They allow excel­lent arti­cu­la­ti­on and direct con­trol. The musi­ci­an can con­cen­tra­te on what’s essential.

Institute for Music Acoustics, Vienna

The Insti­tu­te for Music Acoustics at the Uni­ver­si­ty of Music and Per­forming Arts Vien­na sup­ports daCar­bo with detail­ed acousti­cal and vibra­tio­nal mea­su­re­ments on our pro­to­ty­pes. This enab­les a cus­tom-made design pro­cess for the instru­ments, taking into account their sound and intonation.

Mea­su­re­ment on daCar­bo instru­ments show that they have a hig­her ener­gy out­put – mea­ning that the play­er needs less ener­gy to pro­du­ce the same sound, and will tire less quick­ly. This cor­re­sponds exact­ly to what musi­ci­ans tell us when they test-play the instruments.

Handiwork meets high-tech

daCar­bo has deve­lo­ped an injec­tion tech­no­lo­gy to manu­fac­tu­re com­plex tube shapes from car­bon mate­ri­als. Using this tech­no­lo­gy, daCar­bo pro­du­ces wind instru­ment com­pon­ents cha­rac­te­ri­zed by per­fect sur­face qua­li­ty insi­de the tubes and out. The pro­cess gua­ran­tees a dura­ble, uncom­pro­mi­sing finish, much more exact than could be achie­ved using tra­di­tio­nal instru­ment-makers’ tech­ni­ques. Nevertheless each instru­ment is built with pain­sta­kin­gly pre­cise, hand-craf­ted detail and built by our instru­ment-makers with love and care.
