A honeycomb sandwich panel is produced by (a) mounting a honeycomb core on a lower prepreg laminate skin placed on a forming die, (b) superimposing thereon an upper prepreg laminate skin to cover the honeycomb core, (c) mounting flat plate-shaped elastic jigs on a portion of the resulting assembly where the lower prepreg laminate skin and the upper prepreg laminate skin are overlapping each other, (d) superimposing flat plate-shaped press jigs on the elastic jigs, and (e) heating the assembly under pressure for adhesion forming.

A forming jig used for forming a fiber-reinforced composite structure from a plurality of first fiber-reinforced composite preforms la, 1b, . . . linearly arranged at given intervals and one or more second fiber-reinforced composite preforms 2a, . . . passing through gaps between adjacent two first preforms and intersecting a row of the first preforms 1a, 1b, . . . comprises a combination of (a) elastic jigs 5 engageable with the intersections of the row of the first preforms 1a, 1b, . . . and the second preforms 2a, . . . , and (b) rigid jigs 6, 6′ attachable to the first preforms 1a, 1b, . . . and the second preforms 2a, in portions of these preforms other than the intersections.
摘要:
A method for efficiently producing a stiffened hollow structure from a first skin member, a second skin member and a stiffener each made of a fiber-reinforced composite with reduced steps, the stiffened hollow structure comprising a hollow skin portion and a stiffening portion for strengthening the hollow skin portion from the inside. The method comprises the steps of: (1) disposing the first skin member and the second skin member on the stiffener, an adhesive being provided between the stiffener and each of the first skin member and the second skin member; (2) placing a band on the outer surface of the first skin member and the second skin member; and (3) setting the adhesive while tightening the band and applying a tensile force to the first skin member and the second skin member.

A novel fiber-reinforced composite member having at least one projection is formed by (a) disposing a preform made of a fiber-reinforced composite material on a forming plate; (b) placing a shape-retention means composed of a plurality of soft unit members adjacent to each projection of the preform; (c) completely covering the preform and the shape-retention means with a bagging film having a sealant attached to the periphery; (d) adhering the sealant to the forming plate such that the preform and the shape-retention means are completely sealed by the bagging film; (e) evacuating the inside of the bagging film; and (f) heating the preform under pressure to form a fiber-reinforced composite member.

A bread baking apparatus having a bread container, a mixer for mixing ingredients in the container to form a dough, and an oven for baking the dough, and further having a storage unit for storing a plurality of bread types, bread recipes and bread processing operating times, a display unit for displaying the plurality of bread types, a selection unit for selecting one of the displayed bread types, with the display unit further displaying the recipe of the selected bread type, a control unit for controlling the time of operation of the apparatus, and a start unit for starting the mixing and baking. A method of baking bread utilizing such baking apparatus.
摘要:
A method for bonding a plurality of non-magnetic members includes the steps of (1) mating the non-magnetic members via an uncured adhesive interposed between their surfaces to be bonded; (2) applying pressure to their mated portions between a pressing magnet jig and a pressure-receiving, soft-magnetic jig; and (3) curing the adhesive while applying pressure.
