With a U-shaped cross-section that stretches in the longitudinal direction and a covered layer (3) that surrounds and partially or completely covers the core. And the hollow seal (11) is coherent to the outer surface (4) of the fuselage, which has been characterized by the fact that the mantle (3) is made of a thermosetting compound. A thermoplastic elastomer with at least 350% elongation at break from the initial pull as determined by the corresponding value. With the Japanese industrial standard JIS K6251 and the conversion in 100% modulus at most 40% where the change in 100% modulus = [(100% modulus at 23 ° C - modulus 100% at 80 ° C) / 100% modulus at 23 ° C] x 100 and 100% modulus is the tensile stress at 100% elongation as determined in accordance with JIS K6251 and the A hollow seal (11) made from a thermoplastic elastomer compound with a minimum tensile elongation of 250% as determined in accordance with JIS K6251 and The compaction set is 35% or less, as determined at 25% compressive strength 70 ° C, 200 hours. The body part (1) and the hollow crystal (11), where the body (1) consists of a core (2) made of resin. With a U-shaped cross-section that stretches in the longitudinal direction and a covered layer (3) that surrounds and partially or completely covers the core. And the hollow seal (11) is coherent to the outer surface (4) of the fuselage, which has been characterized by the fact that the mantle (3) is made of a thermosetting compound. A thermoplastic elastomer with at least 350% elongation at break, as determined by the standard. Japan Industry (JIS) K6251 and at most 40% modulus replacement at 100% modulus = ((100% modulus at 23 ํ - modulus) 100% modulus at 80 ํ) / 100% modulus at 23 ํ x 100 and 100% modulus is the stress at 100% elongation as determined by IIS K6251 and the hollow seal (11 ) Made up of a mixture of thermoplastic elastomers With at least 250% tensile elongation as determined from JIS K6251 and compaction set of 35% or less, as determined at 25% compression force 70 ํ. 200 hours
