Abstract: A method for improving the impact resistance of a fiber-composite part includes positioning fibers within an expected impact region of the part, wherein at least a portion of most of the positioned fibers is oriented to be within about 45 degrees of parallel to an impact vector of an impact that occurs at the impact region. At least some of the fibers in the impact region should have relatively high impact resistance, such as glass fiber or aramid fiber, and the matrix in the impact region should have relatively high impact resistance.

Abstract: A fiber component has at least three fiber rods which each have fibers extending continuously in the axial direction of the fiber rods, wherein at least two of the three fiber rods each form a support rod and at least one of the three fiber rods forms a connecting rod. The support rods are arranged substantially parallel in the axial direction thereof and spaced from each other. The connecting rod connects the support rods to each other. The connecting rod forms a node point with the support rod in question at each of the connecting points between the connecting rod and the support rods.

Abstract: A tie rod suitable for use with known concrete forming systems is constructed from a non-metal fiber, such as fiberglass, that is wound about a pair of opposed thimble elements. The resultant tie rod is as strong as a metal tie rod without the drawbacks of conventional metal tie rods. Each of the thimble elements has a main body having a channel formed in an outer surface of the main body, and the fiberglass fiber is disposed within the channel when wound thereabout.

Abstract: A stiffened part formed from at least two members of thermoset composite material including at least one body of a first structure and optionally a second structure. A manufacturing method includes: forming a fibre preform and impregnating each body of the first structure with thermosetting resin or forming a pre-impregnated fibre preform to obtain a body formed from uncured thermosetting composite material supported by a mandrel; optionally partially or fully polymerising at least one body supported by a mandrel; optionally, providing the second structure formed from uncured, partially uncured or fully uncured thermosetting composite material; optionally, depositing a layer of uncured thermosetting adhesive on an area where a fully cured member makes contact with another member of the part; joining the members, each member being juxtaposed with; or stacked upon, at least one other member; fully curing the assembly by heat treatment; removing the mandrel from each fully cured body.

Abstract: The invention provides a method for preparing a fiber-reinforced part based on cyanate ester or a cyanate ester/epoxy blend, comprising the steps of (i) providing a liquid mixture comprising (a) from 15 to 99.9 wt. % of at least one di- or polyfunctional cyanate ester, (b) from 0 to 84.9 wt. % of at least one di- or polyfunctional epoxy resin, and (c) from 0.1 to 25 wt. % of a metal-free catalyst; (ii) providing a fiber structure (iii) placing said fiber structure in a mold or in a substrate, (iv) impregnating said fiber structure with said liquid mixture, (v) curing said liquid mixture by applying a temperature of 30 to 300° C. Using the method of the invention it is possible to produce in a short cycle time, using composite manufacturing processes such as resin transfer molding and infusing technology, fiber reinforced composite parts based on a cyanate ester or cyanate ester/epoxy resin formulation. The fiber-reinforced parts obtainable by the above method are also an object of the invention.
