Figure 7 montrent que la <strong>qualit\u00e9 de la couture assemblant le mat\u00e9riau<\/strong> a une incidence d\u00e9terminante sur la r\u00e9sistance globale du mat\u00e9riau. La couture cr\u00e9e des <strong>concentrations de contraintes locales<\/strong> provoqu\u00e9es par des entailles \u2013 les trous d\u2019aiguille \u2013 qui r\u00e9duisent la r\u00e9sistance \u00e0 la traction de l\u2019ensemble. La rupture s\u2019est produite au niveau de la zone cousue, et non dans la partie continue du mat\u00e9riau. Cela indique que la couture est le <strong>point le plus vuln\u00e9rable<\/strong> de l\u2019ensemble du parachute.<\/p>\n<p><\/p>\n<p><strong>4.2<\/strong> La diff\u00e9rence entre deux bandes de tissu cousues \u00e0 la sangle porteuse du parachute principal et le mat\u00e9riau ripstop seul est d\u2019environ <strong>50\u00a0N<\/strong>, soit environ <strong>15\u00a0%<\/strong>. Cette diff\u00e9rence r\u00e9sulte des raisons d\u00e9crites dans la conclusion 4.1. Une comparaison similaire ne peut pas \u00eatre faite pour le mat\u00e9riau utilis\u00e9 dans le parachute extracteur, car un <strong>seul essai de traction<\/strong> du mat\u00e9riau seul a \u00e9t\u00e9 r\u00e9alis\u00e9. Toutefois, \u00e0 en juger par l\u2019emplacement de la rupture des \u00e9chantillons cousus \u00e0 la sangle, une relation similaire est probable.<\/p>\n<p><\/p>\n<p><strong>4.3<\/strong> Les mat\u00e9riaux ripstop et leurs coutures pr\u00e9sentent dans les deux cas une <strong>r\u00e9sistance \u00e0 la traction similaire<\/strong>, mais comme indiqu\u00e9 \u00e0 la section 3.A, la <strong>qualit\u00e9 de la couture<\/strong> joue un r\u00f4le important. Le <strong>mat\u00e9riau le plus r\u00e9sistant<\/strong> parmi ceux test\u00e9s est la sangle porteuse, qui est environ <strong>trois fois plus r\u00e9sistante<\/strong> que la liaison \u00ab\u00a0cousue en boucle\u00a0\u00bb.<\/p>\n<p><\/p>\n<hr \/><\/p>\n<p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-48b90bb9 e-flex e-con-boxed e-con e-parent\" data-id=\"48b90bb9\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-4fb5a720 elementor-widget elementor-widget-text-editor\" data-id=\"4fb5a720\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Cet article a \u00e9t\u00e9 rendu possible gr\u00e2ce \u00e0 la collaboration avec le cercle scientifique \u00e9tudiant <strong>PWr in Space<\/strong>, plac\u00e9 sous le patronage de l\u2019<strong>Universit\u00e9 des sciences et technologies de Wroc\u0142aw<\/strong>.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-26d6d0b0 e-grid e-con-boxed e-con e-parent\" data-id=\"26d6d0b0\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-1af1a62e elementor-widget elementor-widget-image\" data-id=\"1af1a62e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"250\" height=\"250\" src=\"https:\/\/www.ripstop.be\/wp-content\/uploads\/2026\/02\/pwr-in-space-small.jpg\" class=\"attachment-large size-large wp-image-34487\" alt=\"\" srcset=\"https:\/\/www.ripstop.be\/wp-content\/uploads\/2026\/02\/pwr-in-space-small.jpg 250w, https:\/\/www.ripstop.be\/wp-content\/uploads\/2026\/02\/pwr-in-space-small-150x150.jpg 150w, https:\/\/www.ripstop.be\/wp-content\/uploads\/2026\/02\/pwr-in-space-small-100x100.jpg 100w\" sizes=\"(max-width: 250px) 100vw, 250px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Tests de r\u00e9sistance Ce document pr\u00e9sente les r\u00e9sultats des tests de r\u00e9sistance r\u00e9alis\u00e9s le 20 mars 2024 sur des mat\u00e9riaux en nylon 40D et sur les coutures utilis\u00e9es dans un parachute principal et un parachute extracteur&#8230; <a class=\"more\" href=\"https:\/\/www.ripstop.be\/fr\/tests-de-resistance-a-la-traction-et-des-coutures-en-nylon\/\"> Lire la suite &rarr;<\/a><\/p>\n","protected":false},"author":444,"featured_media":34985,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_post_was_ever_published":false},"categories":[1038],"tags":[],"class_list":["post-34984","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-non-classifiee"],"acf":[],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 5.0.3 - aioseo.com -->\n\t<meta name=\"robots\" content=\"max-image-preview:large\" \/>\n\t<meta name=\"author\" content=\"Marcin Jerzak\"\/>\n\t<link rel=\"canonical\" href=\"https:\/\/www.ripstop.be\/fr\/tests-de-resistance-a-la-traction-et-des-coutures-en-nylon\/\" \/>\n\t\t<meta name=\"generator\" content=\"All in One SEO (AIOSEO) 5.0.3\" \/>\n\t\t<meta property=\"og:locale\" content=\"fr_FR\" \/>\n\t\t<meta property=\"og:site_name\" content=\"Ripstop.be | Sklep na mi\u0142o\u015bnik\u00f3w projekt\u00f3w DIY.
