#CMT# #/CMT# The method involves creating a straight arrangement (12) of reinforcing fibers (11), and impregnating the arrangement with a liquid resin composition after degassing the arrangement. The impregnated product is passed to impart the shape of a tape (21) to the product. Surface treatment is applied on an upper face of the tape to obtain a solid skin. The tape is placed on a holder/mandrel (23) that determines the final shape of a composite block. The tape is unidirectionally wound on the holder by superimposing its layers to form a continuous ring on holder, where the layers are less than 15. #CMT# : #/CMT# An independent claim is also included for a device for fabricating a closed geometry composite block. #CMT#USE : #/CMT# Method for fabricating a composite block e.g. continuous ring, with closed geometry based on reinforcing fibers and a crosslinkable resin, that is utilized for fabricating an elastic non-pneumatic tire of a motor vehicle. #CMT#ADVANTAGE : #/CMT# The method permits fabrication of a composite block with high quality in a simple manner, while eliminating a stabilizing chamber and its series of ultraviolet irradiating tubes, thus reducing fabrication cost of the composite block. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic representation of a composite block fabricating device for implementing a fabricating method. 11 : Straight arrangement 12 : Reinforcing fibers 13 : Vacuum chamber 17 : Impregnation composition 21 : Tape 23 : Holder/mandrel #CMT#POLYMERS : #/CMT# The resin composition is a crosslinkable resin e.g. vinyl ester resin such as epoxy vinyl ester resin with a novolac or bisphenol base. The reinforcing fibers are constituted by glass fibers and carbon fibers. |
