A woven or nonwoven web, or film (e. g. polyimide) or foil is coated with a homogeneous cured composition comprising a liquid mixture of thermosettable resin(s) such as a polyepoxide and curative(s) such as aromatic polyamines and particles of an amorphous thermoplastic polymer such as a polyetherimide. The particles have an average diameter of from 0. 5-50 micrometers, a surface area of at least 1. 0 m. sup. 2 /g, a dissolution temperature of at least 50. degree. C. , and are insoluble in the thermosettable resin at temperatures of up to 15. degree. C. below the dissolution temperature but are completely dissolved at a temperature of at least 20. degree. C. below the cure temperature of the resin.

A thermosettable resin composition having a viscosity that decreases during processing temperatures and increases as the temperature is raised to curing temperatures is provided The composition comprises thermosettable resins and thermoplastic particles that are insoluble in the thermosettable resins at processing temperatures but soluble in the thermosettable resins at curing temperatures. Prepregs prepared from the thermosettable resin composition are also provided.

A thermosettable resin composition is prepared by admixing a liquid mixture of thermosettable resins such as a polyepoxide and amorphous thermoplastic polymer particles such as a polyetherimide to form a homogeneous cured resin composition. The particles have an average diameter of from 0. 5-50 micrometers, a surface area of at least 1. 0 m. sup. 2 /g, a dissolution temperature of at least 50. degree. C. , and are essentially insoluble in the thermosettable resin at temperatures of up to 15. degree. C. below the dissolution temperature but are completely dissolved at a temperature of at least 20. degree. C. below the cure temperature of the resin.

An air filter includes filter media, a sensor, and circuitry coupled to the sensor, the circuitry configured to receive data from the sensor representative of the condition of the filter media and wirelessly transmit such data. The data may be received by a device with a display to use the information to present an indication of the filter media condition to a user.

An expandable air filter device. The air filter device includes first and second air filter units and an expansion joint. The air filter units each include a filter media assembly and an outer frame assembly. The filter media assembly defines a perimeter. The outer frame assembly is arranged around the perimeter. The expansion joint is connected to and extends between the outer frame assembly of the first air filter unit and the outer frame assembly of the second air filter unit. In some embodiments, the expansion joint is expandable from a collapsed state to an expanded state. A gap between the first and second air filter units is greater in the expanded state than in the collapsed state, with the expansion joint spanning the gap, serving to impede flow of un-filtered air through the gap during use.
