HOLLOW PART, PARTICULARLY TUBE COMPOSED OF LONG FIBER-REINFORCED PLASTIC AND MANUFACTURE OF SAID HOLLOW PART

摘要

PURPOSE: To obtain a hollow component, in particular a tube, of a long fiber reinforced plastic by having a force induction element integrated on one end, its jacket comprising a part of the hollow component itself and surrounding a tie end as well as a core. CONSTITUTION: A hollow component 1 includes a force induction element 2 forming an integral part thereof. It is made of a polyester resin with glass fiber reinforcements embedded. Its jacket 3 consisting of a laminate is formed as a radial enlargement 4 of the hollow component and tapers towards its free end 5 into a narrow section 6. The length of the radial enlargement 4 including its narrow portions 7 and 8 is approximately equal to 1.0 times the internal diameter of the hollow component 1. The radial enlargement 4 further has the diameter of the hollow component 1 increased on average to about 1.3 times that of the hollow component 1. The jacket 3 of the enlargement 4 is in the polygonal form of a hexagon. It encloses an expansion element 9 made of aluminum which is acted upon by a clamping member 10. The clamping member 10 merges into a tie rod 11 which is anchored in a foundation.
