This proposal describes an effort to implement the aypex braiding process. work to be conducted includes weave design, fabrication demonstration, impregnation and test and evaluation.

The clean air act requires that certain exhaust emissions standards be met by heavy duty trucks and busses (class 8 vehicles) powered by diesel engines. the limits set for 1998 can only be met thru the use of exhaust treatment devices. a novel woven ceramic yarn filter capable of high temperature… More

A new textile process has been developed by Techniweave that employs multidirectional weaving in the fabrication of integrally woven, net shaped, complex components. The process has been demostrated manually and has been shown through design of equipment to be feasible for an automated system. The… More

A unique textile process has been developed by Techniweave that employs multi-directional weaving. The process has been adapted to the fabrication of complex confirgurations that are potentially applicable as composite fittings in several areas within future aircraft designs. Lockheed Aircraft… More

Today, the majority of sandwich structures on aircraft involve a honeycomb and/or foam core with adhesive bonded face sheets. But, there are problems associated with conventionally cored composites. Honeycomb cored composites are expensive and vulnerable to a variety of environmental threats and… More

The latest generation of three dimensionally reinforced carbon/epoxy composites have demonstrated the ability to carry significantly higher ultimate loads than conventional laminated composites in structural configurations such as T-sections. The failure modes of these composites are complex… More
