Toho Tenax Europe has been developing Tenax Net Shape Preform technology and their latest developments enhance new possibilities for thermoset matrix composites with the combination of aligned fibres and random oriented material.
According to Toho Tenax, the patented process combines continuous and random carbon fibres allowing more flexibility for part designs tailored to optimal stiffness & stress requirements. They say that while the aligned fibres can take up high stresses, random fibres can achieve curved shapes as well as complex three-dimensional geometries which also allow high productivity. This development allows an optimisation of weight and cost of for thermoset matrix composites components.
A preform of a generic automotive A-pillar with the combination of aligned and random carbon fibre is being shown for the first time at JEC Europe this week.
Toho Tenax say their Net Shape Preforms are storable at room temperature and have the shape and contour of the final part. They are injected with thermoset resin to complete the final composite component. They say that manufacturing of composite components at reduced costs is reached in a lean process chain. This newly developed technology avoids high carbon fibre waste which is inherent with existing carbon fibre manufacturing technologies.
Composite products, based on polyurethane technologies from global chemical company Huntsman, are taking centre stage at a design exhibition at the Design Museum Gent, Belgium.
The Brazilian composite sector expects to close 2018 with a turnover of US$ 685 million, a high of 3.8% compared to the previous year.
Brazilian company Tecniplas has supplied two composite elution columns to mining company Leagold.
