Zusammenfassung:	Otkrivena je kompozitna traka (10) koja se može namotavati da formira spiralnu cijev za transportiranje fluida. Kompozitna traka sadrži: izduljenu plastičnu traku (11) koja ima bazni dio (12), a bazni dio (12) ima gornju stranu koja definira vanjsko lice (15); i barem jedan kompozitni rebreni dio (20) koji se proteže po duljini i uzdiže iz vanjskog lica (15) baznog dijela (12). Rebreni dio (20) ima vanjski kraj (26) udaljen od baznog dijela. Kompozitni rebreni dio sadrži: izduljeni unutarnji armaturni element (30) smješten unutar baznog dijela (12) ili uz njega; izduljeni izvanjski armaturni element (40) smješten unutar vanjskog kraja (26) rebrenog dijela (20) paralelno unutarnjem armaturnom elementu (30); i izduljeni međudio plastične ispune (23) koji se proteže između unutarnjeg i izvanjskog armaturnog elementa (30, 40). Kada se namota u spiralnu cijev, kompozitni rebreni dio (20) ojačava cijev protiv radijalnih opterećenja na lom. A composite strip 10 windable to form a helical pipe for transporting fluid is disclosed. The composite strip comprises: an elongate plastic strip 11 having a base portion 12, the base portion 12 having an upper side defining an outer face 15; and at least one lengthwise extending composite rib portion 20 upstanding from the outer face 15 of the base portion 12. The rib portion 20 has a distal end 26 remote from the base portion 12. The composite rib portion comprises: an elongate inboard reinforcing member 30 disposed within or adjacent to the base portion 12; an elongate outboard reinforcing member 40 disposed within the distal end 26 of the rib portion 26 parallel to the inboard reinforcing member 30; and an elongate intermediate plastic web portion 23 extending between the inboard and outboard reinforcing members 30, 40. When wound into a helical pipe, the composite rib portion 20 reinforces the pipe against radial crushing loads.
