Изобретение относитс к способам изготовлени слоистых изделий.The invention relates to methods for the manufacture of layered products.
Известен способ изготовлени силового элемента из стеклопластика, состо щий в выкладке предварительно пропитанных армирующих слоев на цулаге, в отверждении и введении стержней-иголок по толщине стеклопластика . По известному способу введение стержней-иголок осуществл ют после отверждени стеклопластика в просверленные в нем по толщине отверсти , что приводит к неререзыванию нитей армирующих слоев и тем самым к снижению несущей способности силового элемента.A known method of manufacturing a fiberglass strength element, consisting in laying pre-impregnated reinforcing layers on the curb, in curing and inserting the needle-needles through the thickness of the fiberglass. According to a known method, the insertion of the rods-needles is carried out after the fiberglass is cured into the holes drilled in it through the thickness, which leads to the nonreflection of the threads of the reinforcing layers and thereby to a decrease in the carrying capacity of the power element.
Предлагаемый способ не имеет указанного недостатка, он отличаетс тем, это стержнииголки ввод т неред операцией отверждени , а также тем, что стержни-иголки выполнены спаренными в виде П-образной скобы, перемычку между которыми удал ют после операции отверждени .The proposed method does not have this disadvantage, it differs in that these needles are inserted non-destructively by the curing operation and also by the fact that the needle-rods are paired in the form of a U-shaped clevis, the jumper between which is removed after the curing operation.
Способ по сн етс чертежом.The method is explained in the drawing.
Способ изготовлени силового элемента из стеклопластика состоит в выкладке пакета слоев армирующего материала 1 па цулаге 2, в который через перфорированную цулагу 3 вставл ют спаренные перемычкой П-образные стержни-иголки и сверху накладывают цулагу 5, преп тствующую выталкиванию иголки при прессовании. Дл обеснечени прохождени A method of manufacturing a fiberglass force element consists in laying out a stack of layers of reinforcing material 1 on the pallet 2, into which, by means of a jumper, U-shaped rods-needles inserted through a perforated tsulag 3 are inserted and a torsula 5 is put on top, which prevents extrusion of the needles during pressing. To enable passage
иголок на всю толщину материала и исключени возможности искривлени их при приложении давлени под полуфабрикат на цулагу 2 укладывают м гкий разделительный слой 6, например стеклоткань, покрытую целлофаном или прорезиненную ткань. После этого пакет помещают в автоклав дл отверждени под давлением. После прессовани механически обрезают перемычки стержней-иголок 4 и снимают отвержденную деталь , в которую по толщине заформованы металлические иголки.needles over the entire thickness of the material and excluding the possibility of their bending under pressure when a semi-finished product is applied to the pulley 2, a soft separating layer 6 is laid, for example fiberglass, covered with cellophane or rubberized fabric. The bag is then placed in an autoclave for pressure curing. After pressing, the lintels of the pins and needles 4 are mechanically cut and a hardened part is removed, into which the metal needles are molded in thickness.
