Abstract
A support beam for a long functional unit, specifically in a paper and/or coating machine, including a long hollow body having a round or polygonal cross section and manufactured from a fiber reinforced material which was produced in a winding process, whereby the invention provides that the fiber reinforced material is one having a modulus of elasticity of >100 Gpa, and a heat expansion of ≦2×10−6 1/° K in its longitudinal direction, as well as a fiber orientation whereby a first fiber content of 70% to 90% is approximately parallel to the longitudinal direction and a remaining second fiber content is aligned in the circumferential direction.
Claims4
A support beam for use in one of a paper machine and coating machine, said support beam comprising:
- a hollow body with a longitudinal direction, a circumferential direction and one of a round and a polygonal cross-section, aid support beam being made of a fiber reinforced material with a plurality of first fibers and a plurality of second fibers, said fiber reinforced material having a modulus of elasticity of greater than 100 Gpa, and a thermal expansion coefficient of not greater than 2×10−6 1/° K in its longitudinal direction, between approximately 70% to 90% of said first fibers being aligned substantial y parallel to said support beam longitudinal direction, said plurality of second fibers being substantially aligned to said circumferential direction of said hollow body.
