Composite laminate structures are produced using partially cured parts. Partial curing of the parts is achieved by applying a catalyst to regions of the parts that are to be fully cured. These regions cure at a lower-than-normal temperature while remaining regions of the part remain uncured, allowing them to be co-bonded or co-cured to other structures.

An induction board for use in a roof system. The induction board includes a base and an adhesive covering the base or a portion of the base. Metal wire which may in the form of a metal wire mesh, is coated with the adhesive and disposed over the base. The metal wire may be used as a susceptor in an induction heating process. The roof system also includes a roof deck on top of which the induction board is secured and a membrane over the induction board. The adhesive activates with the addition of heat created during the induction heating process to adhere all or part of the membrane with the induction board.

The disclosure relates to a component device, in particular for a primary supporting component of an aircraft, the component device having a first component element, a second component element, a bonding providing a connection between the first component element and the second component element, and a detector device having at least one interior space sensor device configured to measure a change in a pressure and/or a concentration of a gas surrounding the interior space sensor device. The first component element, the second component element, and the bonding confine an interior space. The interior space sensor device is arranged in the interior space.

A composition comprises a cyanoacrylate polymer and a protected amine. A method comprises: providing a shaped model comprising a cyanoacrylate polymer; preparing an investment having a cavity that corresponds to the shaped model; and heating the shaped model to sufficient temperature that the cyanoacrylate polymer depolymerizes and volatilizes. A hardenable material may be cast in the investment to provide a replica of the shaped model. A curable composition comprises: a cyanoacrylate monomer; a free-radical photoinitiator; and a protected amine, wherein the curable composition is free of compounds that initiate anionic polymerization of the cyanoacrylate monomer at ambient temperature. A method of curing the curable composition is also disclosed.

The present disclosure relates to a nontoxic poly(ethyl cyanoacrylate) (PECA) plastic. The PECA-based plastic is sourced from non-petroleum feedstocks and can be thermally and/or mechanically converted back to the ethyl cyanoacrylate monomer in a closed-loop recycling system with high monomer recovery. The disclosure also provides for methods of making the PECA plastics and methods of recycling the PECA plastics.
