Provided herein is a high performance reactive pressure sensitive adhesive (HPR-PSA) formulation which can be compounded and coated on facestock at ambient temperatures. Upon curing by exposing to a high temperature, the HPR-PSA becomes a structural adhesive with superior mechanical performance. This HPR-PSA formulation comprises the unique mixture of the SIS and SB rubber, hydrocarbon and rosin resins tackifiers, and a phenolic derivative curing agent.

A method for producing a component includes a) providing at least two preforms each made of a carbon composite material, b) joining the at least two preforms at least at one respective connecting surface to form a composite, in which a joining compound is introduced between the joining surfaces of the preforms and then cured and the joining compound contains silicon carbide and at least one polymer adhesive, and c) siliconizing the composite to form the component. A component, such as an optical component produced thereby, is also provided.

An adhesive strain sensing pod includes at least one strain sensor, electronics for electrically sensing at least one strain signal from the at least one strain sensor, and a sensor adhesive for adhering the strain sensor to a surface of a structural element. The pod may have a protective case for protecting the strain sensor and the electronics and for transferring at least part of a force, pressing the pod against the surface, to press the strain sensor against the surface. The sensor adhesive may be a liquid adhesive contained in a fragile pouch that ruptures when the pod is forced against the surface, or may be a thermally activated adhesive film that is activated to bond the strain sensor to the surface. A protective film may protect the sensor adhesive prior to installation of the pod and is removed prior to installation of the pod on the surface.
