Researchers at the Massachusetts Institute of Technology (MIT) have developed a new theory to predict the amount of light transmitted via a material, considering its level of stretch and thickness. Based on this theory, the researchers were able to successfully predict the varying transparency of a rubber-like, transparent polymer as it was stretched and inflated.
The study exhibits a unique method, using ultrasonic waves to accurately position a huge number of tiny reinforcement fibers as part of the 3D printing process. The fibers form a microscopic reinforcement framework to provide the material strength, a focused laser beam is then used to position this microstructure. Finally, the epoxy resin is cured and the object is printed.
Market research suggests that the glass fiber and special chemical fiber sector will grow annually by 6.47% from 2015 to 2020. Hyun-Dai Fiber.Co.Ltd. have been using their expertise and technical know-how to manufacture and supply various fibers - from superfine glass fiber to carbon fiber - in order to meet the demands of its customers.
Hexcel is pleased to have its innovative CFRP technology introduced in the BMW 7 Series where it is used to save weight and reinforce the metal shell of the B-pillar. Hexcel supplies BMW with preforms made of unidirectional carbon prepreg set in various orientations and combined with adhesive. The prepreg is made from Hexcel’s HexPly® M77 resin system that cures in 1.5 minutes at 160°C.
Seashells, lobster claws, and chalk are all composed of calcium carbonate crystals but the first two are tough to break, while the third is soft enough to draw on pathways. This is because the hard materials contain bits of soft biological matter, which provides them with strength.
A new alloy with cold-loving features is reported to be one of the toughest metallic alloys ever, according to a team of Berkeley Lab researchers.
The new fibre composite and light-weight construction trade fair “Experience Composites – powered by JEC” will take place in Augsburg between 21st and 23rd September 2016 for the first time. The creators of the event, Messe Augsburg, the JEC Group and Carbon Composites e.V. are working with great passion, meticulousness and high demands towards creating a trail-blazing event for the growing composites market. The offer has already been greatly welcomed. A range of renowned companies, both domestic and from abroad, have already declared their intention to attend. The event will showcase composites companies and applications in two halls with around 10,000 m2 and will involve strong exhibitors positioned according to application.
The largest composites exhibition in the world relocates in a bigger venue with a new name: JEC World. Taking into account the growing demand of its exhibitors, the event will be able to increase its space in a controlled and monitored Parc Paris Nord Villepinte.
The ARION1 Land Speed bicycle, designed and built by The University of Liverpool Velocipede (ULV) Team, has recently competed in the IHPVA “World Human Power Speed Challenge”, which took place from the 14-19 September 2015. Now in its 16th year, this annual speed trial event attracts engineering teams from all over the world to test their designs and their rider’s endurance on the famous five mile highway road at Battle Mountain, Nevada in the USA.
In the coming year a new event called "Experience Composites - powered by the JEC Group" will be staged in Augsburg from 21 to 23 September 2016 in a Multi-Location-Format.
