PRODUCING AN STRONG THREAD PROFILE FOR JOINING COMPOSITES

[Category : - OTHER]
[Viewed 30 times]

An optimized thread profile (140) for joining composite materials is presented. This thread profile (140) maintains a certain material strength when used as part of a composite threaded joint (101). The thread profile (140) comprises a repeating pattern of four components: a crest region (150), a first flank (162), a root region (170) and a second flank (164). The thread profile (140) is symmetrical, that is, the dimensions of the four components do not change throughout the length of the thread profile. The crest (152) has a flat profile and the root (172) has a rounded profile. When a shaft (120) is affixed to a joining shaft (110) using this optimized thread profile (140), the flat profiles of the crest (152) of the shaft (120) and corresponding rounded profiles of the root (172) of the joining shaft (110) create a gap to accommodate a substance such as an adhesive or a lubricant. Similarly, the flat profiles of the crest (152) of the joining shaft (110) and corresponding rounded profiles of the root (172) of the shaft (120) create a gap to accommodate a substance.rnThe thread profile is designed for use in composite fracking tools and other high-load applications. It is engineered to withstand the mechanical stresses encountered during fracturing operations. The geometry allows for the application of adhesives or lubricants, providing adequate clearance for added compounds without affecting structural integrity.
