A group of scientists from the Skoltech Center for Design, Manufacturing and Materials (CDMM) and University of Salerno (Italy) focused on improving pultrusion process productivity by optimizing pulling speed and structural parameters. They discovered and analyzed the interconnection between pulling speed of pultrusion and severity of manufactured induced shape distortions, matrix cracking and delaminations, mechanical characteristics. The research results are recently published in the journal Composite Structures.


In recent years, fiber reinforced polymers (FRPs) have garnered considerable interest from the engineering community, resulting in the widespread adoption of composite structures. Among the many current composite manufacturing processes, pultrusion is the most efficient, combining high production rates with low material waste.

It is well known that the construction market is highly competitive. Therefore, every manufacturer is seeking for the possibility to increase productivity while still maintaining optimum structural characteristics of the produced elements.

Battelle Awarded $46.3 Million Contract to Support Manufacturing of Materials for Extreme Hypersonic Environments

Battelle has won a potential seven-year, $46.3 million contract to help the Department of Defense support the manufacture of thermal protection materials that can withstand extreme hypersonic environments.

The Manufacturing of Carbon/Carbon Composites for Hypersonic Applications (MOC3HA) initiative seeks to rapidly mature and integrate manufacturing innovations that will accelerate the production of carbon/carbon composites.

The Air Force Research Laboratory received five bids for the Indefinite Delivery/Indefinite Quantity (ID/IQ) contract and will obligate $6.3 million in fiscal 2020 research, development, test and evaluation funds at the time of award.

“Battelle made a strategic decision a little over a year ago to re-examine the basic process used for creating critical high-temperature carbon materials that are used in hypersonic vehicle shells and structures,” said Andy Kirby, Research Lead for Space and Hypersonics. “Currently it’s a very expensive, time-consuming process that doesn’t lend itself to the scalability needed to meet the increasing demand for

Nano Dimension Announces Sale of Two DragonFly LDM Systems for Additive Manufacturing of Electronics

Sunrise, Florida, Nov. 05, 2020 (GLOBE NEWSWIRE) — Nano Dimension Ltd. (Nasdaq: NNDM), a leading Additively Manufactured Electronics (AME)/PE (Printed Electronics) provider, today announced that it has sold additional two DragonFly LDM systems for additive manufacturing of electronics. The systems were purchased by an Australian defense contractor and by an Asia-Pacific research center.

In a statement to the Company’s shareholders, Yoav Stern, CEO and President of Nano Dimension commented: “While these two new customers represent our main target markets during the COVID-19 era – defense contractors and research centers, the significance justifying noticing these transactions is that they may be the early birds of recovery, at least for the APAC marketplace. One of the transactions was delayed from Q1/2020. We have also noticed that the APAC geography is showing indications of recovery faster than other regions. We believe that the United States is still in

Manufacturing Is A Career, Not A Job

If you think manufacturing is a low-skilled, low-paid industry, think again.

Has manufacturing missed out on an entire generation of skilled workers?

In Connecticut, manufacturing is a major player in the economy—bringing 161,000 jobs, $14.9 billion in wages and $123 million in corporate income tax to the state. It’s too big to fail, but the state’s manufacturing training structures have atrophied.

Around 1980, high school machining and other manufacturing programs started falling by the wayside as parents and educators increasingly embraced a “college for all” mindset. With no students seeking those critical skills, schools reoriented their resources elsewhere.

This all began to turn around in 2010, when the state realized the pressing need to invest in manufacturing training. In Connecticut alone, the manufacturing sector needs to fill 6,000–8,000 positions every year just to keep up with attrition. Thirty-five percent of the state’s manufacturing workforce is 55 years old or
