A dry, fibrous tape for use in an automated placement process such as ATL or AFP and a preform produced therefrom. The preform is configured for resin infusion. The tape contains a layer of unidirectional fibers, at least one nonwoven veil bonded to one side of the fiber layer, and at least binding materials present within the tape. The preform produced from laying down such tape exhibits a low-bulk property that is close to the final thickness of the cured fiber-reinforced resin article and no further consolidation or compaction is required.
一种用于 ATL 或 AFP 等自动贴片工艺的干纤维胶带,以及用其生产的预成型件。预型件用于树脂灌注。胶带包含一层单向纤维、至少一层粘合在纤维层一侧的无纺面纱,以及胶带内至少存在的粘合材料。铺设这种胶带生产出的预型件具有低堆积特性,接近固化纤维增强树脂制品的最终厚度,无需进一步加固或压实。
