A filtration element with a fiber-reinforced shell and a method for fabricating the same. The fabrication method including the steps of: i) coating a multi-strand fiber with a liquid resin, ii) winding the coated fiber about the cylindrical filtration element, and iii) solidifying the resin to form a fiber-reinforced shell. The method is characterized by utilizing a spliced fiber formed by: a) aligning an end of a first multi-strand fiber with an end of a second multi-stand fiber such that the aligned fibers extend along a common axis (X), b) wrapping a layer of a heat-shrinkable film about the outer diameter of the aligned ends of the fibers wherein heat-shrinkable film includes a layer of adhesive that contacts the overlapping strands of the fibers, and c) heating the film so that the film draws inward upon the aligned ends of each fiber and forms an integral bond such that the effective cross-sectional area of a section of fiber.
