Pultrudering er den eneste sande kontinuerte produktionsteknik til støbning af forstærket plast.
Processen er karakteriseret ved ringe indsats af manuelt arbejde og højeffektiv forarbejdning af råmaterialer
til profiler til attraktiv pris og konsistent kvalitet.
Pultrusion is the only true continuous production technique for molding reinforced plastics.
The process is characterized by low manual labor and highly efficient processing of raw materials
into profiles at attractive prices and consistent quality.
Pullwinding er en viderudvikling af pultruderingsprocessen.
Hos Plasit ApS har vi anvendt denne proces gennem mange år og derigennem opnået stor erfaring.
Processen gør det muligt at forsyne profilet med armering, som ligger i tværgående retning i forhold til længdeaksen.
Dette øger profilets styrke meget, idet den kraft som holder profilet sammen på tværs, nu ikke kun
skal fremkomme som styrken af den limfuge der er mellem armeringstrådene, men tillige forstærkes af den tværgående armering.
Dette er specielt en stor fordel i tyndvæggede emner.
Pullwinding is a further development of the pultrusion process.
At Plasit ApS, we have used this process for many years and have gained a lot of experience in this process.
The process makes it possible to provide the profile with reinforcement that is transverse to the longitudinal axis.
This greatly increases the strength of the profile, as the force that holds the profile together transversely now not only
has to appear as the strength of the adhesive joint between the reinforcement wires, but is also reinforced by the transverse reinforcement.
This is especially a great advantage in thin-walled items.
Alle fibre som kan modstå procesbetingelserne (temperatur, træk) er egnede som pultruderings-råmaterialer.
Det er muligt at blande fibertyper (hybrid) og opnå specielle egenskaber.
All fibers that can withstand the process conditions (temperature, tensile strength) are suitable as pultrusion raw materials.
It is possible to mix fiber types (hybrid) and achieve special properties.
Fiberglass is often used.
Glass is an effective electrical and thermal insulator and can withstand breakage without permanent deformation.
Glass-based composites can also be colored.
Fiberglass is used in many applications such as boatbuilding, automotive, and construction.
It is robust, durable, and easy to shape, making it popular in various industries.
Its low weight and high strength make fiberglass an ideal choice, especially where high-performance materials are required.
Its resistance to corrosion makes it suitable for outdoor projects and maritime applications.
Aramid fibers, known as Kevlar, have high tensile strength.
Plastic-to-Kevlar adhesion is problematic, resulting in poor compressive and flexural strength.
Kevlar is effective at damping vibrations, but absorbs more water than fiberglass and carbon fiber.
It has a low coefficient of thermal expansion and dimensional stability.
Kevlar is also known for its high impact strength and toughness, however, its yellow color can create challenges with dyeing.
Surface treatment with paint is an option.
Carbon fiber offers a high degree of stiffness, strength, and light weight.
It is electrically conductive, has a negative thermal expansion coefficient, acts as an effective heat conductor, and allows the penetration of X-rays.
Due to its black color, it is not possible to dye carbon fiber, but the surface can be painted to customize its appearance.
Carbon fiber is used in a wide range of applications such as aerospace, motorsport, sports equipment, and construction.
Its extreme strength and lightweight properties make it popular in the design of light and strong structures.
Carbon fiber composites are also used in ships, cars, and bicycles to reduce weight and improve performance.
The continued development of carbon fiber technology opens up exciting opportunities in manufacturing and engineering.
Der findes fire hovedgrupper af anvendelige plasttyper til pultrusion; Polyester, vinylester, epoxy og phenol.
Valg af plasttype er afgørende for de endelige egenskaber hos kompositten.
Polyester anvendes til applikationer uden specielle krav. Vinylester giver gode mekaniske egenskaber og god kemisk bestandighed.
Epoxy anvendes hvor meget gode statiske/dynamiske egenskaber ønskes (god vedhæftning til fibrene).
There are four main groups of usable plastic types for pultrusion; Polyester, vinyl ester, epoxy and phenol.
The choice of plastic type is crucial for the final properties of the composite.
Polyester is used for applications without special requirements. Vinyl ester provides good mechanical properties and good chemical resistance.
Epoxy is used where very good static/dynamic properties are desired (good adhesion to the fibers).
The material is primarily made of polyester.
There are several varieties of polyester to choose from depending on the properties the final product needs to have.
Not all polyester types are suitable for pultrusion, but there are a number of standard polyesters on the market that work well for the purpose.
Polyester can be roughly divided into two main categories: ortho- and isopolyester.
Isopolyester can have better properties than orthopolyester, such as tensile strength, chemical resistance and weather resistance.
Isopolyesters are often preferred for pultrusion and have good chemical and mechanical properties, especially against acids.
Stærk kemisk resistens over for syrer, alkalier og diverse opløsningsmidler, sammen med holdbarhed under alle vejrforhold og korrosionsbestandighed, er kendetegnende for vinylester.
Dens imponerende mekaniske egenskaber gør den velegnet til brug sammen med kulfibre.
Vinylester er en alsidig polymer kendt for sin fremragende modstandsdygtighed over for kemikalier og vejrforhold. Denne egenskab, kombineret med styrken og holdbarheden, gør den til et ideelt valg i mange industrielle anvendelser.
Vinylester har vundet popularitet inden for produktion af kompositmaterialer, hvor den bruges til at forstærke strukturer og komponenter med kulfibre for at opnå letvægtsdesign med høj styrke.
Med sin brede anvendelighed og pålidelighed er vinylester en pålidelig løsning, der imødekommer behovene i forskellige sektorer, herunder byggeri, transport, vindenergi, marineindustrien og meget mere. Denne alsidige polymer fortsætter med at vise sit værd som en pålidelig og effektiv komponent i materialer, der kræver overlegen modstandsdygtighed og holdbarhed.
Strong chemical resistance to acids, alkalis and various solvents, along with all-weather durability and corrosion resistance, are the hallmarks of vinyl ester.
Its impressive mechanical properties make it well-suited for use with carbon fibers.
Vinyl ester is a versatile polymer known for its excellent resistance to chemicals and weathering. This property, combined with its strength and durability, makes it an ideal choice in many industrial applications.
Vinyl ester has gained popularity in the production of composite materials, where it is used to reinforce structures and components with carbon fibers to achieve lightweight, high-strength designs.
With its wide applicability and reliability, vinyl ester is a reliable solution that meets the needs of various sectors, including construction, transportation, wind energy, the marine industry and more. This versatile polymer continues to prove its worth as a reliable and effective component in materials that require superior resistance and durability.
Normalt har epoxy en lav krympning under hærdningen, hvilket resulterer i gode mekaniske egenskaber og har generelt gode kemiske egenskaber, afhængigt af hærdningssystemet.
Ved korrekt anvendelse og hærdning kan produktet opnå optimal ydeevne og holdbarhed.
Det er vigtigt at sikre korrekt blanding af materialer og passende hærdnings-betingelser for at opnå ønskede egenskaber og lang levetid, derfor er vi meget bevidste om at produktionen kræver tid og omhyggelighed, for at vores produkter opretholder en god kvalitet.
Normally, epoxy has a low shrinkage during curing, which results in good mechanical properties. Generally, it has good chemical properties, depending on the curing system.
When used and cured correctly, the product can achieve optimal performance and durability.
It is important to ensure correct mixing of materials and appropriate curing conditions to achieve desired properties and long life, therefore we are very aware that production requires time and care in order for our products to maintain good quality.
Phenol is ideal for fire risk due to minimal smoke development. Retains strength up to 200° C.
Used in industry for heat-resistant processes such as plastic and pharmaceutical production.
