Abstract: A non-woven mat useful for a wide variety of purposes, including forming reinforced resin products, is produced in a manner having different specific uses of, and advantages over, conventional chopped strand mats and conventional glass tissue. The mat is preferably made by the foam process (but may be made by the liquid process), and at speeds well in excess of 60 m./min., and has a substantially uniform construction even when low density (e.g. 100 g/m or less). At least 20 % (preferably at least 85 %) of the fibers are in fiber bundles with between 5-450 fibers/bundle. The fibers (typically at least 85 %) have a length between 5-100 mm, preferably 7-50 mm, substantially the same as the length of the fiber bundle they are in. The fibers are preferably held in the bundles by substantially non-water soluble sizing, such as epoxy resin or PVOH. The fibers in the bundles typically have diameters of approximately 7-500 microns, preferably about 7-35 microns. The bundles may comprise at least 10 % reinforcing fibers, such as glass, aramid or acrylic.
Abstract translation: 用于各种目的的无纺布垫，包括形成增强树脂产品，以与常规短切纤维毡和常规玻璃纸组织不同的特定用途和优点的方式生产。 垫优选通过泡沫方法制造（但可以通过液体方法制成），并且速度优于60m /分钟，并且即使当低密度（例如100g / m 2）时也具有基本均匀的结构 <2>以下）。 至少20％（优选至少85％）的纤维是纤维束，其中5-450纤维/束。 纤维（通常为至少85％）的长度为5-100mm，优选为7-50mm，基本上与其所处的纤维束的长度相同。纤维优选通过基本上不变的纤维束保持在束中， 水溶性上浆，如环氧树脂或PVOH。 束中的纤维通常具有约7-500微米的直径，优选约7-35微米。 束可以包括至少10％的增强纤维，例如玻璃，芳族聚酰胺或丙烯酸。

Abstract: The present invention relates to a method and apparatus for foam forming, wherein fibrous foam suspension is introduced from the head box (78, 178) of a production machine to the web forming section thereof. At least one solid material is mixed into the foam in the head box (78, 178). The method and th e apparatus of the invention are particularly suitable for manufacturing vario us web-like products of cellulose, glass fibre, aramide, sisal, or other corresponding fibre material.
