[参赛作品]狼狗为何优秀---谈复合材料成型工艺的复合。(让图片说话)
第一回:缠绕怎么和RTM睡在了一起?不错!跟着邓先生开眼界啊! 好帖子,开眼界
老邓,搞快,等你的文字! 对头~
没得文字不参与评奖~ 第二回呢 ? 第二回:拉和挤从来就是一对儿,wound却成了可耻的第三者。
Reinforced-composite tubing and hollow profiles are produced by means of pull-winding, which reportedly minimizes wall thickness and weight while maintaining material stiffness and strength compared with conventional pultrusion technology. The process, which results in products that are 80% lighter than steel and 30% lighter than aluminium, is suited for the fabrication of medical devices where a high stiffness-to-weight ratio and nonmagnetic properties are desirable. A wide range of diameters and wall thicknesses and varied resins and reinforcement materials are available for applications such as resonance imaging tables, prostheses, and x-ray fixtures.
谢楼主分享,这东西刚出来的时候着实把我吓了一跳,当时都没听过pull-winding这词儿,这么多年了也不知道国内做的咋样儿,没了解过。 续第二回:第三者转了正了---“缠拉挤”才是下面图片的意思。不过有一张图用来生产玻璃纤维增强热塑性塑料管很不错的。
