Composite structures for submarines require high strength and high fracture toughness to survive underwater shock blasts. These structures have historically been built using rubber-toughened epoxy pre-impregnated (pre-pregs) reinforcements. However, experience has shown that pre-pregs can be difficult to work with, especially for thick section parts, and require expensive, size-limited, autoclav ...

The successful Phase I effort to incorporate POSS into BMI resin resulted in substantial Tg and HDT improvements while reducing the cure temperature. The proposed Phase II effort will optimize the formulaiton while characterizing the full scope and range of enhancement in filament wound composite structures.

Hybrid Plastics proposes to develop a low cost, and versatile method for shielding commercial, military, and stacked microelectronics against the deleterious effects of space radiation. The technical approach utilizes metallized nanoscopic polyhedral oligomeric silsesquioxanes as conformal coatings or potting agents. Such coatings would permit spacecraft designers to use commercial ICs in applicat ...

A thick SiC epitaxy process was demonstrated by SemiSouth in Phase I, as the growth (or deposition) rate was boosted from 5 um/h to 20 um/h, and thickness uniformity was kept to 5% or below. In the Phase 2 effort, it is proposed that the processes be developed for production by re-designing and optimizing the reactor susceptor in a research reactor to minimize cost and risk. Specifically, the su ...

ABSTRACT: Several new high-power, long range radar systems are under development for near-term upgrades or fielding by MDA, Navy, and Marine Corps, which will use High Voltage GaAs or new WBG Semiconductors (SiC, GaN) in the transmitter/receiver. These systems will require compact, efficient, temperature tolerant power supplies and converters typically requiring a 600 V class of power devices. ...

"This SBIR Phase II Proposal seeks to develop the physics-basedfault tolerant technology for sensor networks shown to befeasible in the SBIR Phase I study in response to topic N01-080, "Fault Location in an Intelligent Open Sensor Network." Theproposed approach considers that for Conditional-BasedMaintenance purposes an entire ship can be classified as ahierarchy of subsystems, which conceptually ...

Hybrid Plastics proposes to develop a low cost, and versatile method for shielding commercial and military solar cells from damage against proton and electron radiation. The technical approach utilizes metallized nanoscopic polyhedral oligomeric silsesquioxanes as conformal coatings on coverglass and on solar cell surfaces. Such coatings would permit spacecraft designers to increase duty cycles wh ...

The goal of this proposal is to study the feasibility SiC rectifiers in high-voltage, high total current applications. Specifically, the Schottky barrier diode (SBD), JBS diode (JBS), and PiN diode device structures will be studied with strengths andweaknesses of each approach examined based on the system application needs and SiC material maturity. The insertion of SiC into high total current s ...

"The proposed SBIR program offers a unique opportunity to use design and fabrication technology developed in recent government and industry funded programs to design a low-cost, high-performance, light-weight, low-noise propeller for Small UAV's. Global Aircraft Corp.(GAC) has the technology to design and manufacture composite propellers with scimitar shaped blades that flex to change pitch. Th ...

"Mississippi Polymer Technologies, Inc. (MPT), in cooperation with Atlantic Research Corporation, proposes to develop ultra-high performance Parmaxr Self-Reinforcing Polymers (SRPs) for ramjet combustor applications. Parmaxr SRPs, which offer strengthscomparable to mild steels and specific strengths comparable to titanium alloys, are thermoplastic polyparaphenylenes with superior ablative propert ...
