초록 ▼

The invention provides improvements to a composite member that has a plurality of plies. The improved composite member has (1) an interior ply which functions to dampen or resist sudden forces exerted on the composite member, (2) an intermediate load-carrying ply, and (3) an exterior abrasion-resistant ply. These plies have multiple, often intertwined fiber components disposed or imbedded with a matrix material, preferably Nylon-6 thermoplastic, to inhibit sharp edges during breakage. One or more of the plies typically has “bi-axial”or “tri-axially”braided fiber geometries wherein one or more fibers are helically wound about the circumference of the member. The helically oriented fibers are oriented at a selectively variable angle which influences the overall bending strength of the composite material. In one aspect, the angles of the fiber components and other factors are used to maintain substantially uniform cross-sectional area over the length of the tubular member while simultaneously varying the bending stiffness. A composite member constructed according to the invention resists sudden or impact forces and has high, selectively variable bending strength, high impact resistance, and safe failure modes.

대표청구항 ▼

In an axially extending composite member having a plurality of plies and having primary bending stiffness along a longitudinal axis, the improvement comprising A) at least one interior ply structured with a matrix material and with a first fiber component clockwise helically oriented and bi-axially braided with a second fiber component counter-clockwise helically oriented for providing a first fraction of the bending stiffness of said composite member and for providing impact resistance, B) at least one intermediate ply structured with i) said matrix material, ii) an axially extending third fiber component having a first helical orientation relative to said longitudinal axis, iii) a fourth helically oriented fiber component interwoven with said axially extending third fiber component and oriented clockwise relative to said first helical orientation, and iv) a fifth helically oriented fiber component interwoven with said axially extending third fiber component and oriented counter-clockwise to said first helical orientation, said intermediate ply being exterior to said interior ply and providing a second fraction of the bending stiffness and providing primary load-carrying strength of the member, and C) at least one exterior ply exterior to said intermediate ply said exterior ply structured with said matrix material and with a sixth fiber component clockwise helically oriented and bi-axially braided with a seventh fiber component counter-clockwise helically oriented for providing a third fraction of the bending stiffness and for providing abrasion resistance, wherein said second fraction is greater than either of said first and third fractions.
