One-part epoxy changes from red to clear under UV

Master Bond UV15RCL is a low-viscosity, cationic-type UV-curing system with a special color-changing feature. The red material changes to clear once exposed to UV light, indicating that there is UV light access across the adhesive material. Although this change in color from red to clear does not indicate a full cure, it does confirm that the UV light has reached the polymer. This epoxy is an excellent electrical insulator. UV15RCL adheres well to metals, glass, ceramics, and many plastics, including acrylics and polycarbonates.

Couplings solve misalignments more precisely with targeted center designs

ALS Couplings from Miki Pulley feature a simplistic, three-piece construction and are available in three different types for more precisely handling parallel, angular, or axial misalignment applications. The key feature of this coupling design is its center element. Each of the three models has a center member that has a unique and durable material and shape. Also called a "spider," the center is designed to address and resolve the type of misalignment targeted. Ideal for unidirectional continuous movement or rapid bidirectional motion.

Army tests aluminum foam for blast protection

Aluminum foam is inexpensive to produce, and it can be made into various sizes and shapes, including panels. While it is currently manufactured and shipped from South Korea and Canada, several companies in the United States are interested in expanding production to make aluminum foam.

By Argie Sarantinos, U.S. Army CCDC

Forward Operating Bases are typically surrounded by barbed wire, concrete barriers, gates, watchtowers, and other infrastructures. A new material -- aluminum foam -- may be a possible solution for additional force protection, due to its ability to absorb energy from blasts.

The aluminum foam is added to panels clad with steel that are part of existing structures or bolted together to create larger structures. The panels are also used in jersey-style barriers to protect against truck bombs.

Aluminum foam was recently tested in a lab and at an explosives testing range at Picatinny Arsenal, New Jersey, with funding from the Office of the Under Secretary of Defense - Global Capability Programs Foreign Comparative Testing program. The FCT program provides funding to acquire, test and evaluate mature products from foreign industry that may fill a capability gap or satisfy an urgent need. The aluminum foam is manufactured in South Korea and Canada.

"In products where you need a good amount of strength and stiffness that aluminum provides but not all the weight, using the foam opens up a lot of engineering design space without increasing cost," said Calvin Lim, engineer at Picatinny Arsenal.

Aluminum foam is inexpensive to produce, and it can be made into various sizes and shapes, including panels. While it is currently manufactured and shipped from South Korea and Canada, several companies in the United States are interested in expanding production to make aluminum foam. Creating an affordable supply chain in the U.S. will eliminate difficulties with shipping the product outside the country and create additional jobs in the U.S.

Testing to verify and confirm the manufacturers' claims was conducted at Picatinny Arsenal. Explosives were initiated next to the aluminum foam panels, which were held in place with I-beams.

"These tests showed how the aluminum foam prevents energy from being transmitted to the other side. To fully replicate previous test data, a higher amount of explosives is needed,'' Lim said.

Testing was initially conducted in South Korea; during testing, the panels absorbed the energy from the blast, collapsing the material's cellular structure and preventing any damage from transmitting to the other side. The tests at Picatinny Arsenal, as well as upcoming tests, will determine if aluminum foam will be beneficial for the Army overall, as well as other services.

The FCT program provided funding to purchase additional aluminum foam for Insensitive Munitions testing with XM1128 artillery. This was proposed as a low-cost, easy-to-implement packaging solution to reduce the sensitivity and collateral damage in sympathetic reaction and fragment impact scenarios. This testing has been slated but delayed due to the coronavirus pandemic.

In addition to military uses, aluminum foam is used in a variety of applications including sound mitigation, highway barriers, and storm debris mitigation because of its unique properties.

Because of its versatility, aluminum foam has sparked interest and possible use for military ground vehicles, aircraft, and watercraft due to its low weight, stiffness, and buoyancy. Lighter vessels and vehicles will not only move faster and use less fuel, they will require fewer refueling trips and enable Soldiers to maneuver more easily.

The Army is working with several companies on additional energy and resource savings, including an energy-conscious solution that melts raw scrap aluminum to create aluminum foam. This will reduce steps in the recycling supply chain, which will lead to cost savings.

Future efforts could include using aluminum foam to rapidly manufacture, ship, and erect buildings quickly in key locations. Recent research shows many allied countries and adversarial countries have already been using aluminum foam to protect civilian and defense employees.
