ASTM D5365-23由美国材料与试验协会 US-ASTM 发布于 2023-07-01。
ASTM D5365-23在国际标准分类中归属于: 23.040.20 塑料管。
1.1 This test method covers a procedure for determining the long-term ring-bending strain (Sb) of “fiberglass” pipe. Both glass-fiber-reinforced thermosetting-resin pipe (RTRP) and glass-fiber-reinforced polymer mortar pipe (RPMP) are “fiberglass” pipes. 1.2 The values stated in inch-pound units are to be regarded as the standard. The SI units given in parentheses are for information only. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. A specific warning statement is given in 9.5. NOTE 1—There is no known ISO equivalent to this standard. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
树脂有着广泛的应用范围,包括涂料、粘合剂、碳纤维增强复合材料、玻璃纤维增强复合材料(当然,聚酯、乙烯基酯以及其它热固性树脂也常用于玻璃纤维增强塑料)。 ...
玻璃钢(FRP)也称作SMC,即纤维强化塑料,一般指用玻璃纤维增强不饱和聚脂、环氧树脂与酚醛树脂基体。以玻璃纤维或其制品作增强材料的增强塑料,称为玻璃纤维增强塑料,或称玻璃钢。原来,玻璃钢不是玻璃不是钢啊!由于所使用的树脂品种不同,因此有聚酯玻璃钢、环氧玻璃钢、酚醛玻璃钢之称。玻璃钢的特点质轻而硬,不导电,机械强度高,回收利用少,耐腐蚀等可以代替钢材制作的各种机器零件、汽车、船舶外壳等。...
(2)增强材料 常用的增强材料有玻璃纤维粉、玻璃纤维和玻璃微珠。为了增加增强材料与树脂的粘接强度,上述增强材料都采用增强偶联剂进行表面处理。 ...
它是以合成树脂为基体材料,玻璃纤维及其制品作为增强材料的复合材料。根据合成树脂的不同,玻璃钢可以分为环氧玻璃钢、酚醛玻璃钢、聚酯玻璃钢。说起来,玻璃纤维制作过程也是一个化腐朽为神奇的过程。它是以废旧玻璃作为原料,经过高温熔制、拉丝、织布等工艺制作而成。原来硬而脆的玻璃制成玻璃纤维后变得高强度、高柔韧性、抗腐蚀性好,但只能承拉,不能承受弯曲、剪切、压应力。...
