摘要:
The present invention provides glass fiber strands impregnated with non-abrasive solid particles which provide interstitial spaces of at least 3 micrometers between adjacent fibers within a strand which are useful for reinforcing composites.
摘要:
A hollow carbon microcoil with the coil pitch of substantially zero, and a hollow ceramic microcoil or a hollow ceramic microfiber prepared by subjecting the hollow carbon microcoil to metallization or other treatments. The hollow carbon microcoil with the coil very densely and orderly wound is characterized by being prepared by strictly regulating reaction conditions in the synthesis of carbon in a microcoil form by catalytically activated thermal decomposition of acetylene and allowing a substrate to descend as the fiber grows. A high-temperature reaction/diffusion treatment of the above hollow carbon microcoil as a starting material in a gas containing various metal components, silicon, boron, carbon, nitrogen and/or oxygen atoms at 800 to 1700 DEG C results in the formation of the hollow ceramic microcoil or microfiber wherein carbon has been reacted or substituted with the starting gas component while completely retaining the hollow of the axis of the fiber.
摘要:
The present invention provides glass fiber strands coated and impregnated with greater than 20 weight percent of inorganic particle fillers which are useful for reinforcing composites.
摘要:
The present invention relates to a process for preparing a textile coated with a conducting polymer functionalized with fluorinated chains. It also relates to a polymer-coated textile obtainable by such a process.
摘要:
The present invention provides glass fiber strands coated with non-hydratable, inorganic solid lubricant particles useful for reinforcing composites such as laminated electronic supports.
摘要:
The present invention provides methods for inhibiting abrasive wear of glass fiber strands by providing a layer of inorganic solid lubricant particles to surfaces of the glass fibers in sliding contact with hard surface asperities of solid objects, such as portions of winding, twisting, weaving and knitting devices.
