Abstract: The invention is to perform operations from sealing of a honeycomb core with a thermosetting sealing material having an adhesive property to its hardening in one step, prevent a resin from flowing into cells of the honeycomb core during resin impregnating operation, and thereby mold low-cost honeycomb sandwich components by using RTM technique which is adopted in molding solid materials, for instance. Dry fabric sheets are stacked on both sides of a honeycomb core with thermosetting sealing members having an adhesive property placed in between, and the sealing members and the dry fabric sheets are heated at the curing temperature of the sealing members to cause initial hardening of the sealing members and to dry the dry fabric sheets. Then, the dry fabric sheets are impregnated with a thermosetting resin and the resin impregnated into the dry fabric sheets is hardened by hot-pressing an entire assembly thus prepared under specific conditions.

Abstract: A method for preparing carpet by using polyurethane foam to anneal secondary backing to a greige, comprising fibers attached to a primary backing. The polyurethane monomers are mixed just prior to application to the greige primary backing allowing the relatively low viscosity polyurethane to penetrate the fibers of the primary backing to aid in fiber lock. The polyurethane coated greige is then contacted with the secondary backing before complete polymerization to insure sufficient tack to hold the backings together. Sufficient water is applied through application of steam after the polyurethane components are applied to the greige to completely cure the polyurethane without a curing oven.

Abstract: The invention relates to a glass fibre-reinforced plastic-plate which is provided with an anti-slip coating, consisting of resin and sand, as well as a production process of such a plate. The process according to the invention is a continuous one and does not require manual production steps. Initially, for the production a resin is bonded (10) with glass-fibre mats to a glass fibre-reinforced laminate as base material (20) and heated. As is conventional, the plate (20) is covered on both sides with carrier films (11, 12).

In this stage the upper carrier film (11) is pulled-off and a premixed coating compound consisting of resin and sand is applied (18) from above onto the base material (20). Alternative to the application of a premixed coating material, the resin and sand can be applied separately.
