Definitions

  • Our invention relates to a production method developed in order to increase the strength of the planar plate products such as lower structural components and transport pallets made of composite material dough and SMC or BMC.
  • products that are especially determined in TS 1478 EN 124 standard, steel casting, lamellar graphite cast iron, spheroidal graphite cast iron, malleable casting heavy metals and alloys of light metals, alloys of cast and composite material dough (SMC) is made of unsaturated polyester resin and glass fiber. While preparing the raw material, a variety of glass fiber mesh is used for reinforcing purpose. Existing products are manufactured in large volumes (thick sections) to provide the standard, hence weight and economic disadvantages occurs.
  • the mentioned products are better in respect of volume, weight and economically it is ensured to produce high resistant products against tensile strength, tensile modulus, bending under load, impact resistance, durability losing and especially the vertical impact loads specified in the standards, even on thin sections.
  • the raw material supported by different winding methods is produced in the desired properties by applying pre-strain during the production and using glass fiber which is generated from composite material dough (SMC-BMC) and all kinds of polymers as raw material.

  • Carcass structures (1) can be planar, cylindrical or prismatic depending on the product shape and can be made of wood, meta!, plastic, etc. as the material type. If there is a risk of slipping during winding the glass fibers (3) on carcass structure (1), fiber slots (5) are open on the carcass structure (1).
  • the carcass structure (1) which the winding process was completed is supported by SMC, BMC dough or by a different but compatible filling materia! to complete the overall volume of the product and then the process is completed by pressing at high temperature under pressure.
  • the hardened product can have superior strength values according to known methods.
  • products having desired strength values under control can be produced by using the properties such as number of windings, winding angle, resin absorbing property of the fiber (3), winding of the fiber (3) under variable tension, resin properties and properties of the material which the windings are made of.
  • winding axis (2) is applied in the range-of 1-360 degrees and at least one ea.
  • the winding process on the carcass construction (1) can be made with specially manufactured fiber winding machines (4) or manually.
  • the sample product is produced by winding three windings in four different axes by an angle of 30 degrees on a metal ring carcass construction (1) by the fiber winding machine (4) under fixed tension, low-speed winding and prepared using resin mixture having slow-hardening property, pressing for 30 minutes at 145 °C under 350 bar pressure.

Abstract

L'invention concerne un procédé de production qui a été mis au point pour accroître la résistance de produits plats en plaques, tels que des éléments structuraux inférieurs et des palettes de transport, fabriqués en pâte composite, en SMC (composite à mouler en feuille) ou en BMC (composite à mouler en vrac). La présente invention permet d'éliminer totalement les problèmes des procédés existants et de produire des produits sûrs et économiques conformes aux normes, en renforçant en cours de fabrication des éléments structuraux inférieurs tels que regards de visite, grilles, couvercles, etc., et répondant aux critères techniques exigés par les normes de ces produits. Le procédé selon l'invention consiste à réaliser d'abord une structure de carcasse (1) selon la forme du produit à fabriquer, puis à enrouler des fibres de verre (3) sur cette structure de carcasse (1) selon les axes d'enroulement (2) déterminés à l'aide d'une machine à enrouler de fibres (4).
